Vascular device for aneurysm treatment and providing blood flow into a perforator vessel

摘要

A vascular device includes a body having a first, collapsed configuration and a second, expanded configuration. The body includes a plurality of heat-set strands that are braided such that when the body is in the second configuration, the strands form a plurality of pores and one or more apertures between the strands. The apertures are generally disposed at a longitudinal center region of the body. When the body is in the second configuration, the pores at proximal and distal portions of the body are generally uniform in size and smaller in size than the apertures. The pores and the apertures are substantially the same size when the body is in the first configuration.
