Patent ID: 8545530

Claim:
An implantable aneurysm closure device adjustable from a delivery arrangement in which the device has a generally small diameter configuration to a deployed arrangement in which the device has a larger diameter configuration, the implantable aneurysm closure device comprising: a tapered closure structure having a generally truncated conical configuration, wherein the closure structure comprises an open distal end and is configured to contact at least a portion of an internal wall of an aneurysm when the device is in the deployed arrangement; a closure membrane having a first major surface and a second major surface opposite the first surface, wherein the first surface is coupled with a base of the tapered closure structure, and wherein the closure membrane is sized to substantially cover an opening of the aneurysm when the device is in the deployed arrangement; and an anchoring structure comprising at least two positioning members extending away from the closure membrane and biased toward the tapered closure structure, and wherein, in the deployed arrangement, the at least two positioning members are configured to reside outside the aneurysm and extend generally beyond a periphery of the closure membrane.
