Abstract
Abstract A medical device for interposition between a first flow path and at least one second flow path is provided. The device includes a first surface facing toward the opening of at least one second flow path; and a second surface facing away from the opening of at least one second flow path. When the device is in the operative position, it extends less than the complete circumference of the first flow path and substantially covers the opening of at least one second flow path. The device contains one or more surface features to facilitate chronic implantation. The device further has one or more characteristic porosities. Different configurations are indicated depending on the pathophysiology being treated and dictate the characteristic porosity of the device. In some, cases blood is prevented from reaching the second flow path and in other cases, particulates traveling within the blood are prevented from reaching the second flow path. Methods of preventing emboli or blood flow into the second flow path are also provided. Methods and devices for delivery are also provided.
