Abstract

An aneurysm patch apparatus (10) for treating an aneurysm (30) formed in a vessel includes a vessel interface side (16) and an opposing non-interface side (18). A patch (14) is formed of a sufficiently flexible material to provide a patch stowed state when the patch is delivered through the vessel and a patch deployed state when the patch is at least partially positioned over the mouth of the aneurysm. The interface side of the patch is configured to form an adherence between the patch and an area of a vessel wall adjacent to the aneurysm mouth (28). The adherence (22) maintains a fixed position of the patch relative to the aneurysm mouth and can be achieved by use of vacuum, barbs, hooks, graspers, pinchers or the like. The patch delivery catheter (12) includes a first lumen (32) coupled to a low pressure source for collapsing the aneurysm, and a second lumen (36) for consequently applying adhesive to provide contact between patch and vessel wall.
