Claims12
A device for obstructing blood flow into an aneurysm affecting a blood vessel having an inner wall, said device comprising:
- a flow occluding device having an insertion configuration and a deployed configuration;
- wherein the insertion configuration comprises a substantially straight single length of wire;
- and
- wherein the deployed configuration comprises two hoops adapted to substantially circumscribe the inner wall of the blood vessel and a flow disrupting structure connected between the two hoops.
A device for obstructing blood flow into an aneurysm affecting a blood vessel having an inner wall, said device comprising:
- a flow occluding device having an insertion configuration and a deployed configuration;
- wherein the insertion configuration comprises a substantially straight length of doubled wire bent and its midpoint;
- and
- wherein the deployed configuration comprises two hoops adapted to contact the inner wall of the blood vessel and a flow disrupting structure attached to the two hoops.
A system for inserting and deploying a device for obstructing blood flow into an aneurysm affecting a blood vessel having an inner wall, said system comprising:
- a flow occluding device having an insertion configuration and a deployed configuration and an insertion device;
- the flow occluding device having an insertion configuration and a deployed configuration, wherein the insertion configuration comprises a substantially straight length of wire and the deployed configuration comprises two hoops adapted to substantially circumscribe the inner wall of the blood vessel and a flow disrupting structure connected between the two hoops;
- and
- the insertion device comprising a catheter having a lumen at its distal end, the catheter being sized and dimensioned to allow insertion of the catheter into the body to the site of the aneurysm, said lumen having an internal diameter sufficient to house the flow disrupting device in the insertion configuration.
