Abstract:
The invention includes a vaso-occlusive device comprising at least one substantially linear strand of a vaso-occlusive member wound into a stable, three-dimensional relaxed configuration comprising a plurality of non-overlapping loops, wherein said relaxed configuration self-forms upon release from a restraining member. The relaxed configuration of the vaso-occlusive device may fill a body cavity or, for example, approximate the shape of sphere. The vaso-occlusive devices described herein can include any number of non-overlapping loops, for example in certain embodiments the device will have between about 6 and 20 loops while in other embodiments the device will have between about 6 and 12 loops. The vaso-occlusive devices described herein can be comprised of a metal, for example, platinum, palladium, rhodium, gold, tungsten and alloys thereof. The vaso-occlusive devices described herein may comprise a stainless steel or super-elastic metal alloy or nitinol.
Any of the devices described herein further may include additional filamentary material attached to the vaso-occlusive member, and a deployment tip attached to at least one of the two ends of the vaso-occlusive member. The deployment tip can be, for example, mechanically detachable or electrolytically detachable.
