Patent ID: 8007429

Claim:
An apparatus for occluding a fluid conveying vessel in a body, comprising: an occlusive member having proximate and distal ends, the occlusive member including a conduit region proximately disposed toward the proximate end and a pliable region proximately disposed toward the distal end, the occlusive member being actuatable to an occluding position and actuatable to a non-occluding position where an occlusive force is respectively transmitted to and released from the occlusive member, and where the pliable region is configured to at least partially encircle the vessel and is configured to exert an occluding pressure on the vessel, when the occlusive force is transmitted through the conduit region; and a control mechanism connected to the conduit region of the occlusive member, the control mechanism is configured to actuate the occlusive member into the occluding position and actuate the occlusive member into the non-occluding position, wherein the occlusive member comprises an inner extrusion covered by an outer extrusion, the inner and outer extrusions being porous, where the outer extrusion is less porous than the inner extrusion.
