Patent ID: 8715312

Claim:
A method of treating a vascular aneurysm, comprising: providing an implant having an occlusive member at a first end portion and an anchoring member at a second end portion connected to the occlusive member with wire struts wherein said occlusive member comprises a mesh and has a porous state and a non-porous state and is provided with reactive material that coats at least a portion of the mesh and said reactive material swells in the presence of blood causing said occlusive member to achieve said non-porous state so as to inhibit blood flow into a vascular aneurysm; advancing a delivery device associated with said implant to said vascular aneurysm; positioning the implant in the blood vessel so that the occlusive member is proximate a neck of said vascular aneurysm and permitting the reactive material to swell in the presence of the blood so as to reduce the flow of blood into the vascular aneurysm; deploying the anchoring member in a blood vessel so that said anchoring member anchors the implant in the blood vessel without occluding flow through the blood vessel; and disassociating said delivery device from said implant and withdrawing said delivery device from the vascular aneurysm.
