Abstract:
1. An apparatus for occluding a blood vessel lumen, said apparatus for use with an insertion device, said apparatus comprising: an integral occluding body realized from an elastomeric polymer, said integral occluding body consisting essentially of a blunt distal tip, a frusto-conical portion extending proximally from said distal tip, a disc-shaped portion extending proximally from said frusto-conical portion, and a proximal portion extending proximally from said disc-shaped portion, the diameter of the disc-shaped portion being larger than the diameter of the frusto-conical portion and adapted to be larger than the diameter of the blood vessel lumen in its natural state, the diameter of the proximal portion being smaller that the diameter of the disc-shaped portion; wherein, when the occluding body is inserted by the insertion device axially into the blood vessel lumen, the wall of the lumen of the blood vessel expands and grasps the disc-shaped portion thereof such that the occluding body blocks blood flow through the blood vessel lumen; and wherein at least said proximal portion defines a pilot hole for receiving the insertion device and said proximal portion defines means for receiving retraction means for removal of the occluding body from the blood vessel lumen.
