Endovascular thin film devices and methods for treating and preventing stroke
First Claim
1. A fenestrated thin-film material having a selected film thickness in the range between about 0.5 to 150 microns, and characterized by (i) a martensitic state, (ii) an austenitic state in which the material assumes a preformed, expanded shape, and (iii) a thin-film transition temperature at which the expanse undergoes a transition from its martensitic state to its austenitic state,

Abstract
Devices for excluding aneurysms and treating atherosclerotic disease, for intra-aneurysmal occlusion; and devices for preventing distal emboli. The devices are generally pliable and collapsible thin film devices which can be delivered via a microcatheter into the desired location where they are deployed and undergo either a shape memory phase transformation or in situ polymerization to assume the stable configuration of a permanent endoluminal prosthesis. Prior to being caused to assume their final shape, the devices remain soft, collapsible and pliable to ensure atraumatic delivery through the vascular system. Upon reaching the endoluminal defect in the vessel, the device is extruded from the microcatheter. Devices are also provided for retrieving clots.
