This invention can be embodied in a device for occluding a cerebral aneurysm comprising a series of proximally-and-distally-connected coil loops. This invention can further comprise a stretchable mesh which spans the interiors of these loops. These loops (and the stretchable mesh) overlap to create a coil-and-mesh mass within the aneurysm sac which occludes the aneurysm.
1. A device to occlude an aneurysm comprising: a longitudinal lumen that is configured to be inserted into a blood vessel, wherein this blood vessel is the parent vessel from which an aneurysm has formed;a first flexible longitudinal embolic member that is configured to travel through the longitudin
1. A device to occlude an aneurysm comprising: a longitudinal lumen that is configured to be inserted into a blood vessel, wherein this blood vessel is the parent vessel from which an aneurysm has formed;a first flexible longitudinal embolic member that is configured to travel through the longitudinal lumen and be inserted into the aneurysm sac;a second flexible longitudinal embolic member that is configured to travel through the longitudinal lumen and be inserted into the aneurysm sac; wherein the longitudinal axes of the first and second embolic members are substantially parallel as these embolic members travel through the longitudinal lumen;a stretchable mesh which spans between the first flexible longitudinal embolic member and the second flexible longitudinal embolic member; anda plurality of connections which connect the first and second embolic members at a plurality of locations along the lengths of the embolic members; wherein segments of the first and second embolic members that are not connected by the connections move away from each other after they exit the longitudinal lumen, thereby forming loops within the aneurysm sac; wherein part of the perimeter of a loop is comprised of a segment of the first flexible longitudinal embolic member and part of the perimeter of a loop is comprised of a segment of the second flexible longitudinal embolic member; wherein a loop has a contiguous 360-degree perimeter; wherein the stretchable mesh fills at least 50% of the interior of the loop; wherein these loops are connected by the connections; wherein accumulation of these loops within the aneurysm sac substantially occludes the aneurysm; and wherein the most distal connections are spaced to form loops which are configured to span the circumference of the aneurysm sac but successive contiguous loops become smaller to fill the central space of the aneurysm sac. 2. The device in claim 1 wherein the longitudinal lumen is a catheter. 3. The device in claim 1 wherein the flexible longitudinal embolic members are coils. 4. The device in claim 1 wherein the stretchable mesh is an elastic mesh. 5. The device in claim 1 wherein the stretchable mesh is impermeable to blood flow. 6. The device in claim 1 wherein the stretchable mesh resists blood flow. 7. The device in claim 1 wherein the stretchable mesh fills the entire interior of a loop.
