New variable porosity flow diverter (VPOD) stent design for treatment of cerebrovascular aneurysms

Annu Int Conf IEEE Eng Med Biol Soc. 2011:2011:1105-8. doi: 10.1109/IEMBS.2011.6090258.

Abstract

Using flow diverting Stents for intracranial aneurysm repair has been an area of recent active research. While current commercial flow diverting stents rely on a dense mesh of braided coils for flow diversion, our group has been developing a method to selectively occlude the aneurysm neck, without endangering nearby perforator vessels. In this paper, we present a new method of fabricating the low porosity patch, a key element of such asymmetric vascular stents (AVS).
