In Vitro Patient-Tailored Cerebral Arterial Model for Surgical Simulation

摘要

An in vitro soft membranous model of individual human cerebral artery reproduced with circumferential soft structure for intravascular neurosurgical simulation, preclinical testing, and testing of medical devices, is presented. This anatomical model is constructed with CT or MRI information. Its human-like constitution realizes simulating intravascular neurosurgery accompanied by realistic surgical feel and visco-elastic structural deformation. In this report we also present a novel technique for analyzing stress distribution the presented patient-tailored cerebral arterial model by means of photoelastic effect.
