Publication number: 20200237378Abstract: A novel shape memory polymer (SMP)-based device for surgical treatment of an intracorporeal defect (e.g., a void or anomaly) such as an intracranial aneurysm or fistula. In at least one non-limiting embodiment, the SMP device is a 3D-printed SMP material sized to specifically fit and thus occlude an intracranial aneurysm (ICA). The SMP device may be delivered to the intracorporeal defect via a catheter having a heating mechanism wherein the SMP device is raised above its glass transition temperature as it is deployed, causing the SMP device to return to its permanent shape after it is deployed into the intracorporeal defect. SMP device delivery systems that include the SMP devices, as well as methods of making and using the devices and systems, are also disclosed.Type: ApplicationFiled: January 24, 2020Publication date: July 30, 2020Inventors: Yingtao Liu, Chung-Hao Lee, Bradley Bohnstedt, Robert Kunkel
