Aneurysm treatment device and method of use

An apparatus for treating vascular aneurysms, comprising:

• an occlusive support device comprising a longitudinal axis having first end portion and a second end portion;
• a rounded end cover member forming a longitudinal sidewall at said first end portion of said occlusive support device, wherein said end cover member has an end cover diameter and said end cover is generally perpendicular to said longitudinal axis of said support device, wherein said end cover has an extension along said longitudinal axis of said device that is less than two times said end cover diameter and wherein said end cover member has openings and said end cover member comprises a reactive material that is configured to hydrate upon delivery of the device and to reduce the size of said openings;
• and
• an anchoring member at said second end portion;
• elongated members connecting the first end portion to the second end portion, said elongated members having a length selected to span across a blood vessel adjacent to a targeted aneurysm to connect the anchoring member to the end cover member while minimizing resistance to blood flow through the adjacent blood vessel.

An apparatus for treating vascular aneurysms, comprising:

• an occlusive support device comprising one or more support members forming a first end portion and a second end portion and defining a lumen therethrough;
• and
• a rounded mesh end cover member at said first end portion of said occlusive support device, said mesh end cover member comprised of at least one of said one or more support members, said rounded mesh end cover member forming a longitudinal sidewall;
• wherein said end cover member has openings and said end cover member comprises a reactive material that is configured to hydrate upon delivery of the device and to reduce the size of said openings;
• and
• an anchoring member at said second end portion;
• elongated members connecting the first end portion to the second end portion, said elongated members having a length selected to span across a blood vessel adjacent to a targeted aneurysm to connect the anchoring member to the end cover while minimizing resistance to blood flow through the adjacent blood vessel.
