BIOMODEX LAACS technology takes a new step forward in cardiovascular surgery


Technology from BIOMODEX, a provider of 3D printed anatomical models, was used in the simulation of a complete cardiovascular procedure to simulate left atrial appendage occlusion (LAAO) – a surgery that aims to prevent the formation of blood clots in patients with atrial fibrillation.

Doctors at the Montreal Heart Institute in Montreal repeated the LAAO procedure for the first time in North America using a BIOMODEX biorealistic haptic simulator that contains a 3D printed replica of the patient’s heart.

The successful simulation validated the company’s technology for its ability to reduce surgical errors and improve procedural outcomes.

“The repetition of a specific case was very helpful, especially one in which we used innovative technologies such as the new Abbott Steerable Delivery Sheath for the Amplatzer Amulet obturator and the VersaCross Baylis transeptal system,” said Dr. Reda Ibrahim, interventional cardiologist at the Montreal Heart Institute.

“This realistic simulation allowed us to maximize the success and safety of the procedures. “

BIOMODEX 3D printed heart models

BIOMODEX was founded in 2014 and 3D prints replicas of patient anatomy directly derived from patient-specific medical images such as MRIs and CT scans. 3D printed models mimic the haptic feedback, texture and feel of real human anatomies, helping surgeons validate their medical devices and repeat surgical procedures.

In 2019, the company opened a new U.S. headquarters in Quincy, Massachusetts, containing a 3D printing lab from which the company could manufacture its anatomical replicas for the medical sector. From there, BIOMODEX aimed to distribute the 3D printed anatomical replicas to various physicians, health systems, researchers and medical device manufacturers across North America.

Earlier this year, BIOMODEX launched a new 3D printed training system for the transseptal puncture procedure, which provides a direct route to the left atrium through the in-ear septum that separates the left atrium from the left atrium. right atrium. By emulating the feel, geometry, and haptic feedback of actual heart tissue, the model allows cardiologists to exercise in a more realistic environment and receive more specialized training.

Cardiovascular catheter therapy has helped expand treatment options for patients with structural heart disease. Biomodex has successfully commercialized several products for cardiac neurovascular and structural applications and is rapidly expanding its product portfolio.

The company’s LAACS technology was used to simulate a LAAO procedure for the first time using a biorealistic haptic simulator from BIOMODEX. The breakthrough was achieved by Ibrahim, electrophysiologist Dr Blandine Mondesert and cardiac surgeon Dr Walid Ben Ali, who used a 3D printed replica of the patient’s heart. This replica is part of a new simulator that provides realistic catheter navigation, haptic feedback, transesophageal ultrasound and fluoroscopic imaging.

Based on the patient’s CTA images, BIOMODEX 3D printed a heart anatomy from advanced materials that simulate the biomechanical characteristics and haptic feedback of the heart. LAACS technology reproduces the blood flow and viscosity of the organ and is also compatible with ultrasound. In addition to building surgeon confidence, the repetition aims to help reduce operating times and decrease the risk of complications during surgery.

“The repetition of these new approaches using a patient-specific anatomical model aims to better prepare physicians and potentially improve patient outcomes,” said Ziad Rouag, President and CEO of BIOMODEX. “It was an honor to support Dr Ibrahim and his team. “

The rehearsal and live patient procedure were performed and recorded at the Montreal Heart Institute, before Ibrahim and his team presented their case live at the TVT Structural Heart Summit in Miami, Fla. On July 22. .

Anatomical models printed in 3D

The production of realistic and accurate representations of human body morphology is vital in teaching anatomical knowledge, and as such, 3D printing of such models for educational purposes continues to improve.

Over the past year, the Stratasys OEM 3D printer has provided a software update for its J750 Digital Anatomy 3D printer to better reproduce porous bone structures, fibrous tissue and ligaments, and the medical device manufacturer 3D LifePrints has achieved ISO certification for the quality assurance procedures behind its 3D printed surgical guides and anatomical models.

Elsewhere, US researchers have evaluated the accuracy of 3D printed medical models produced on a Formlabs Form 3B 3D printer that is widely used in medical facilities for dental, surgical and educational applications. More recently, the University of Florence used a 3DUJ-553 3D printer from Mimaki, a manufacturer of large format inkjet printers and cutters, to produce 3D printed anatomical models with a degree of color fidelity. never achieved before.
