Flow diverter for interrupting and bypassing blood flow into aneurysm of cerebral vessels in e.g. brain during aneurysm treatment, has stents, where diverter is designed so that diverter includes size and shape covering only aneurysm region

摘要

The diverter (4) has stents with high mesh density and different porosities of surface. The diverter is designed such that the diverter does not comprise rotational symmetry and includes a size and a shape covering only a region of an aneurysm (2). A metal ring (5) is attached at the diverter as a support of the diverter. A position sensor is attached at a metal meshwork of the diverter and/or the ring. The position sensor indicates three space coordinates and two azimuth angles. A symmetrical axis of the position sensor is not aligned parallel to a longitudinal axis flow of the diverter.
