The Chamberlain Group has contributed innovative tools for medical learning to TSDA Boot Camp each year for the past 10 years. The course provides an experiential foundation and crucial hands-on practice in basic CT surgery operating skills – valuable experience for surgical residents and faculty alike . While Boot Camp 2018 was cancelled due to a hurricane, this year’s event engaged 60 cardiothoracic surgery residents. The result? Aspiring surgeons are now better prepared to enter the operating room at their home programs.
The Heart Cases and Pocket Vessel Anastomosis Trainers used at TSDA Boot Camp were developed by The Chamberlain Group in collaboration with Dr. James I. Fann, MD. A pioneer in the field of immersive and simulation learning and TSDA Boot Camp Program Director, Dr. Fann approached us with the premise that limited exposure and visualization, compounded by technical complexity, had adversely affected resident training in mitral valve surgery. With this in mind he envisioned a heart trainer that was anatomically accurate and compact enough for travel. The Chamberlain Group delivered Heart Case, a portable, safe, and cost-effective training platform for repeat and deliberate practice. Heart Case: Case Study
In the years since its inception we continue to evolve this product line:
- New Heart Case accessories for MIS and other procedures
- Customized Heart Cases and aortic roots for valve implantation training
- Economical pocket sized task trainers for practice anywhere – Pocket Vessel Anastomosis Trainer and replaceable vessels
TSDA Boot Camp 2019 was held September 12th -15th at the William & Ida Friday Center, Chapel Hill, NC

Thank you for the honor of representing the Commonwealth and the region as your exporter of the year honoree. We were delighted to be nominated and to have been chosen for recognition.
I’ve been thinking about exporting – and it strikes me that it’s very much like another international endeavor – travel. When we decide to take our product to an international market, we encounter many of the same things we do when we travel internationally – different languages, different cultures, new customs, new expectations. It’s a little odd at first, and sometimes a little intimidating, but if we are fortunate, both in travel and exporting, these are eye opening moments that expand our world and our world view. They broaden us. They broaden our employees. They broaden our businesses. They give us the opportunity to bring what we have to offer to a new market that may not have known what we produce was available or even possible.
And as with all good travel, a great guide helps. So I would like to thank Sue Mongue of the MSBDC and Ann Pieroway and her colleagues of the Massachusetts Exporting Center for their steady and steadfast guidance of The Chamberlain Group on our adventure into the unknown. Ann, your support has been unwavering and most deeply appreciated.

Sugical Sam launch
Surgical Sam, The World’s First Infant Surgical Team Trainer
► Full Brochure …
We are happy to announce the arrival of the newest addition to The Chamberlain Group family. Surgical Sam, the world’s first beating heart, breathing and bleeding, high fidelity team trainer for pediatric surgery is now available for purchase.
Engage your entire OR team in multiple “Skin to Skin” procedures using Sam’s interchangeable anatomical modules and replaceable organs.
Surgical Sam was co-developed by The Chamberlain Group and Boston Children’s Hospital Simulator Program (SIMPeds)
under the direction of Peter Weinstock, MD, PhD, with Francis Fynn-Thompson, MD, and David Mooney MD, MPH.
The Chamberlain Group is pleased to announce the birth of Surgical Sam – the world’s first fully operable infant surgical team trainer.Surgical Sam Pediatric Surgery team trainer configured for cardiothoracic procedures.
Developed with Boston Children’s Hospital Simulator Progam (SIMPeds) as the centerpiece of their team-training initiatives in pediatric cardiothoracic and general surgery, Surgical Sam is the world’s first beating heart, breathing and bleeding high fidelity team trainer for pediatric surgery. Surgical Sam ‘moves the needle’ on pediatric surgical team training by allowing important steps of surgery to really happen – allowing OR teams to fully immerse in simulations to optimize performance, safety and outcomes for children.
Surgical Sam is built on a “chassis” with interchangeable thoracic and abdominal anatomy. A cannulatable beating heart with replaceable right atrium and aorta is the centerpiece of the cardiothoracic module; the belly component includes a complete GI tract and liver capsule bleed. Both anatomies plug into the baby chassis, including intubation-compatible lungs, radial pulses, and hemodynamic flow to the cavities. The beating heart for the CT procedures can be fed by and synchronized with the output of a patient monitor for enhanced physiologic realism. Emergent resternotomy and redo laparotomy scenarios, developed by the faculty at Boston Children’s Hospital, have been repeatedly performed with each module by full OR teams as part of a multi-year program under the guidance of the BCH Simulator Program director and principal investigator, Peter Weinstock, MD, PhD.
Dr. Weinstock and his colleagues, Francis Fynn-Thompson, MD and David Mooney, MD, MPH, first approached The Chamberlain Group about the project, having learned of the company’s extensive experience in development of custom anatomy for surgical procedures. Unlike patient mannequins that present simulated physiology without the opportunity for extensive operative interaction, Boston Children’s was seeking a deeply immersive experience for the full OR team. Together BCH and Chamberlain, led by company president and design director Eric Chamberlain, collaborated to bring Surgical Sam to life, addressing the heretofore unmet need of high-fidelity team training that engages the entire OR, including surgery, in the care of the smallest of patients.
Surgical Sam premiered at the 6th International Pediatric Simulation Society Symposia and Workshops (IPSSW) meeting in Vienna, Austria in April, 2014.

FOR IMMEDIATE RELEASE
CHAMBERLAIN GROUP SURGICAL TRAINING MODEL FACILITATES NEW TREATMENT FOR CHRONIC RHINOSINUSITIS
Eliminates Need for Cadavers and Accelerates Physician Training
Great Barrington, Mass., (March 17, 2009) – The Chamberlain Group, maker of anatomically accurate surgical training models, is improving how ENT physicians are trained using their new Maxillary Clinical Sinus Trainer. This innovative technology was recently designed for Minnesota-based Entellus Medical to train ENT surgeons on their new FinESS™ Sinus Treatment, a less-invasive treatment that breaks the cycle of chronic sinusitis with immediate relief and lasting results.
Tom Ressemann, CEO of Entellus Medical, said that the Maxillary Clinical Sinus Trainer has dramatically improved efficiencies in time and cost and in how Entellus trains physicians. “Before we had the Trainers, we had to fly physicians in for a training session to work on cadavers, which is a logistic and expensive challenge. The Trainer now allows Entellus to bring the training to physicians, which is much more convenient for these busy surgeons; and it saves time and money.”
CRS affects over 35 million people in the U.S. resulting in 500,000 conventional sinus surgeries a year. FinESS Sinus Treatment is recommended for patients whose symptoms persist or return despite the use of antibiotics and steroids and who do not need, want or can’t have extensive sinus surgery. FinESS does not require the removal of delicate bone or sinus tissue resulting in less bleeding and pain for the patient, and shortens recovery time to hours instead of days.
The treatment is performed with direct access to the affected sinus through a tiny entry point under the upper lip, known as the canine fossa. An endoscope is placed in the sinus pathway and a balloon is fed through the pathway to the treatment site and expanded. Clinical study results published in the American Journal of Rhinology prove the effectiveness of FinESS in keeping treated sinuses open with statistically significant quality of life improvements.
Trainer has Portable Life-like Patient Head and Neck
The Chamberlain Group Maxillary Clinical Sinus Trainer features a life-like patient head and neck with key anatomical landmarks such as the maxillary ostium, the uncinate process, the ethmoid bulla, the nasal septum, and the turbinates. The Trainer’s sinus structure is derived from actual patient CT data which is then replicated as a three-dimensional model. The maxillary sinus anatomy differs slightly on each side of the Trainer so that the trainee is not limited to just one anatomical situation.
Dick Cassidy, Vice President of Sales for Entellus Medical, said ”physicians using the new Chamberlain synthetic head report it is realistic and comparable to the sinus anatomy in a human or cadaver specimen. For Entellus, the Trainer has allowed us to deliver best-in-class training to our customers in a more cost-effective and timely manner, as compared with cadaver training. The Trainer also allows us to bring the FinESS training to the physicians, making it easier for them to be trained during a busy day of treating patients. This new easy training approach is consistent with our easy to learn and easy to perform procedure.”

CHAMBERLAIN GROUP ANNOUNCES TWO NEW ROBOTIC SURGERY TRAINING DEVICES
Reflects Robust Growth of Client Intuitive Surgical’s da Vinci© System; Creating Breakthrough Training Methods as Robotic Surgery Increases
Great Barrington, MA, November 6, 2008 – The Chamberlain Group, producers of anatomically accurate surgical trainers, today announced two new robotic surgery training devices: a comprehensive Uterine Robotic Surgery Trainer and the next generation of its Robotic System Skills Kit, a modular tool for practicing basic skills in robotic surgery.
According to Lisa Chamberlain, The Chamberlain Group’s co-founder, the Uterine Trainer is a lifelike, full-scale model of the human uterus and vaginal canal. It is composed of Chamberlain’s proprietary polymer that looks and feels like living tissue, has appropriate elasticity and can be cut and sutured.
Physicians using the new Uterine Trainer may practice robotic skills used in myomectomy (removal of uterine fibroid tumors), hysterectomy (removal of the uterus) and sacrocolpopexy (correcting vaginal vault prolapse). Ms. Chamberlain pointed out that following a practice myomectomy using the trainer, the physician may perform a colpotomy (separating the uterus from the vagina) which is a skill performed during a hysterectomy. The remaining vaginal canal may then be affixed to mesh and a sacrocolpopexy performed by attaching the mesh to the available sacral tissue.
The Uterine Trainer has a replaceable uterus which permits unlimited practice. Ms. Chamberlain noted that while the trainer is primarily designed for robotic skill training, it may also be utilized for any abdominal approach training including laparoscopy.
Trainers Developed for Intuitive Surgical’s da Vinci© Surgical System
According to Ms. Chamberlain, both the Uterine Trainer and the Robotic System Skills Kit were developed in direct response to the company’s client, Intuitive Surgical, Inc. (Nasdaq:ISRG), a recognized pioneer and leader in robotic surgery, for training on their da Vinci© Surgical System. Industry analysts estimate that over 1,000 da Vinci Systems will be installed in hospitals worldwide by the end of 2008 and that demand is expected to increase.
In robotic surgery physicians use computer-assisted surgical instrumentation yielding greater precision, dexterity and control, the sum of which enables enhanced patient safety, reduced blood loss, less post-operative pain and discomfort, less risk of infection, shorter hospital stay, faster recovery and less scarring . da Vinci© Prostatectomy is the #1 choice for treatment of localized prostate cancer* in the United States and medical experts predict that it will soon become the standard of care for hysterectomy. Growth of hysterectomy procedures using the da Vinci© Surgical System is forecast at 150% per year.
Intuitive Surgical’s da Vinci© Surgical System provides surgeons with the ability to control instruments with the damping of natural tremors in the surgeon’s hand, the ability to safely manipulate very delicate tissues and a three-dimensional, magnified view of the surgical field all through minimally invasive ports in the body.
Intuitive Surgical’s da Vinci Surgical Systems are used by many physicians within urology, gynecology, cardiothoracic surgery, and general surgery . Medical analysts estimate that approximately 600,000 hysterectomies are performed annually in the US alone.
Robotic System Skills Kit Trains On Surgical Skills
The Robotic System Skills Kit is comprised of four different components, each designed to help surgeons practice a specific skill utilizing the da Vinci Surgical System.
The Chamberlain kit includes a Manipulation Skills Set, designed to practice dexterity in handling robotic surgical instruments and manipulating small structures; a Dissection Skills Pod to practice skills by moving through superficial tissue layers to expose deeper vessels; a Suturing Skills Pod designed to practice skills by closure of linear defects; and a Transection Skills Model that enhances skills by carefully cutting within very narrow, defined boundaries.
Chamberlain’s Broad Range of Surgical and Procedure Models
The Chamberlain Group designs and builds models for a broad range of surgical and interventional procedures including cardiothoracic, general and gastrointestinal, reproductive and urological and vascular applications. In addition to Intuitive, Chamberlain provides custom surgical and training models to over 150 medical device manufacturers and hospitals and offers over 500 products it has created and markets.
Ms. Chamberlain pointed out there is a growing demand for better training methods across all types of surgical and interventional procedures and that major hospitals are building surgical simulation laboratories. Highly accurate, mimetic tissue anatomical trainers provide a more realistic and cost-effective alternative to traditional training in the operating room, with animals, or with cadavers, thus reducing patient risk and health care costs.
In addition to training surgeons on robotic skills, the materials are also used to train novice resident surgeons learning basic skills.

BAYSTATE MEDICAL CENTER AND THE CHAMBERLAIN GROUP
RECEIVE STATE GRANT TO DEVELOP SURGICAL TRAINING KIT
John Adams Innovation Institute awards $150k for artificial-tissue project
Springfield, MA (October 28, 2008) – The John Adams Innovation Institute today announced a $150,000 grant to Baystate Medical Center and The Chamberlain Group to support development of a new surgical training system, bolstering the nationally recognized hospital’s position as a leader in medical simulation training. Combining proven simulation training techniques with the use of non-biological replicas of human organs, the project will establish a new standard in surgical simulation training, equipping young surgeons with a level and sophistication of skill previously unattainable.
The project, the Tactility Learning System, is a collaboration comprising medical leaders and surgical experts from Baystate Medical Center and The Chamberlain Group, a western Massachusetts-based company that produces anatomically correct, tissue-responsive medical models. The effort will leverage state-of-the-art simulation technology to open up new market opportunities in the biotech field, while at the same time helping to keep rising healthcare costs in check by helping surgeons operate at a higher skill level–and thus reducing the rate of costly medical errors.
“For a very long time, the standard model of surgical training has been ‘watch one, do one, teach one.’ This system is so realistic that that model is going to change,” said Richard B. Wait, MD, PhD., Chairman of Surgery at Baystate Health. “Now it’s going to be ‘watch one—then practice a dozen—then do one and teach one.’ We’re going to have young surgeons coming to their first procedure better trained and more capable than ever before.”
“In addition to improving health outcomes for the citizens of Massachusetts, Baystate Medical Center is once again demonstrating that robust innovation activity and top medical science and expertise is thriving across the Commonwealth,” said State Sen. Stephen J. Buoniconti, D-Springfield, a longtime supporter of the hospital in its role as an academic and economic center for western Massachusetts.
“To think the first time I visited the Chamberlain Group in Great Barrington I thought I was in a Hollywood Special Effects Studio, but I soon learned that they are on the cutting edge of the most innovative medical technology training, not only in the state but in the country,” said State Rep. William “Smitty” Pignatelli, D-Lenox, a member of the Committee on Higher Education. “Collaborations like these with our fine institutions of higher learning and leaders in the health care industry help reinforce our interest in the life sciences.”
The new system will promote the expansion of Baystate’s role as a national center for simulation training in graduate and continuing medical education, attracting top-tier faculty to the hospital—the western campus of Tufts University School of Medicine—and increasing employment opportunities for specialists in the medical device, plastics, and precision-machining sectors. Investments like this one are also helping the Pioneer Valley become a center of life sciences activity.
“The engine that drives our Commonwealth’s knowledge economy is fueled by innovation and the institutional collaborations that come from it. This surgical training enterprise can catalyze the partnerships necessary for important downstream economic benefits to the region and beyond,” said Pat Larkin, Director of the John Adams Innovation Institute. The Innovation Institute is a division of the Massachusetts Technology Collaborative, the state’s economic development agency for the innovation economy.
The project’s immediate work is the development, production, and validation of a surgical training kit for open bowel surgery, advancing the simulation training curriculum of area academic institutes, and establishing competitive advantages for Baystate’s Simulation Center and Goldberg Surgical Skills Lab and the businesses associated with the training system. The kit will include ultrarealistic artificial bowel tissue, surgical tools and multimedia instructional materials. Eventually, simulated tissue and training materials for other types of surgeries will be available.
“We see the Open Bowel Trainer as the first in what we expect will be an expanding line of products designed for resident training, combining our mimetic tissue with curriculum developed by Baystate faculty,” said Eric Chamberlain, president of The Chamberlain Group. “This potent combination of didactics and hands-on anatomy will address a multitude of surgical education needs, making it possible for centers across the U.S. and worldwide to benefit from the advances we are making collectively.”
“The most important outcome of Baystate Medical Center’s notable leadership in simulation training is improving patient outcomes and the overall quality of our care through innovation in education,” said Dr. Neal Seymour, Chief of General Surgery at Baystate Medical Center and Medical Director of the Baystate Simulation Center and Goldberg Surgical Skills Lab. “But the fact that collaborations like ours with The Chamberlain Group and the John Adams Innovation Institute are leading to new economic opportunity in western Massachusetts, is truly expanding the definition of caring for a community.”
The John Adams Innovation Institute, the economic development division of the Massachusetts Technology Collaborative, is entrusted with management of two public purpose funds. The funds make targeted, strategic investments to strengthen industry clusters, support the research enterprise, and grow the Massachusetts Innovation Economy.
