Patent ID: 8906057

Claim:
A device to treat an aneurysm comprising: at least one core member including a distal end, that is inserted into the aneurysm; and at least one longitudinal flexible member, wherein the longitudinal flexible member is attached to the core member, wherein the longitudinal flexible member is wound with multiple complete rotations around the at least one core member within the aneurysm, wherein the device is in a first state prior to insertion of the core member into the aneurysm wherein the longitudinal flexible member is wound a first number of complete rotations around the core member and this first number can be zero, wherein the device is in a second state after insertion of the core member into the aneurysm wherein the longitudinal flexible member is wound a second number of complete rotations around the core member and this second number is greater than the first number, and wherein accumulation of the at least one longitudinal flexible member within the aneurysm reduces blood flow into the aneurysm; and a guide loop that guides the longitudinal flexible member as the longitudinal flexible member winds around the core member and that encircles the core member, including the distal end of the core member, in a plane which is substantially parallel to the rotational axis of the core member while the longitudinal flexible member winds around the core member.
