Biomodex’ Evias Solution Studied to Rehearse Endovascular Treatment of Complex Unruptured Intracranial Aneurysms


December 17, 2020—Biomodex, a digital health company offering a three-dimensional (3D)–printed solution for patient-specific rehearsal and physician training, announced that findings for the company’s Evias endovascular intracranial aneurysm system solution were presented at SFNR 2020, the 47th Congress of the French Society of Neuroradiology (SFNR) held as a virtual event on December 16-17.

The clinical study was composed of 20 patients with complex unruptured intracranial aneurysms enrolled at CHU Rennes, France. Anthony Le Bras, MD, and Francois Eugene, MD, who are interventional neuroradiologists at CHU Rennes, presented the findings at SFNR. Full results of the study are expected to be published in 2021.

According to the company, the results validate the benefits of using patient-specific 3D models to simulate interventions in advance to help physicians choose the optimal device and approach for each patient and reduce operating times.

Biomodex uses imaging scans, such as CTA and/or 3D rotational angiography, to visualize the inside of blood vessels and organs and create 3D-printed precise models of each individual patients’ unruptured aneurysm. Unlike silicone models, Biomodex models are created using biomechanical responsive advanced materials that simulate the characteristics and haptic feedback of the individual’s anatomy, noted the company.

“Biomodex’s enhanced 3D-printed solution gave us unique insights ahead of the actual procedures,” commented Dr. Le Bras in the company’s press release. “Using the models for preprocedural rehearsals allowed us to know in advance if an approach was going to work and, if not, helped us to determine which medical device would be more effective. This not only boosted physician confidence but also reduced operating times and enabled us to decrease risk of complication during the real procedure.”

Dr. Eugene added, “The biomechanics and haptic feedback are key parts of Biomodex’s technology. The patient-specific models are realistic and can effectively reproduce hard areas inside the bone and soft areas inside the arteries, including the frictions and resistance of slope during procedures. We could also prepare the shapes and sizes of catheters needed.

“Our study shows by metrology’s measurements that the 3D models reliably reproduced intracranial aneurysm features. We believe Biomodex could become the model of care for complex cases and physician training in the future, and eventually be used for other procedures, such as stroke.”
