Advancing Endovascular Treatment: Personalized Device Design through Topology Optimization

 

“Computer simulation comparing blood flow through a cerebral aneurysm before and after placement of a patient-specific implant, showing reduced flow within the aneurysm after treatment.”Associate Professor Shikui Chen along with Dr. Chander Sandasvian (PI, SBU Hospital) and Professor David Gu (CS Department) were awarded an OVPR Seed Grant for their project "Advancing Endocascular Treatment: Personalized Device Design through Toplogy Optimization." This project aims to improve endovascular treatments for vascular diseases like brain aneurysms, aortic aneurysms, and cardiac valve replacements.

Current treatments face limitations due to the non-optimal fit of medical devices to patient anatomy, leading to complications like recanalization, endoleaks, and paravalvular leaks. The project proposes using advanced computational tools, “Patient-specific cerebral aneurysm model and the progressive development of a porous implant through topology-optimization iterations.”particularly Topology Optimization (TO) and computational conformal mapping, to design personalized, patient-matched devices (PMDs).

These tools will help simulate deployable structures that conform accurately to individual patients' vascular anatomy, thereby enhancing treatment efficacy and reducing complications. The project's goal, supported by an OVPR seed grant, includes two main aims: generating patient-specific device designs and enabling effective transcatheter deployment using TO and conformal mapping.
