Abstract:

A multimode occlusion and stenosis treatment apparatus comprises an elongated member having a distal region, and an enclosure secured to the distal region of the elongated member, the enclosure comprising a flow restoring segment, an open segment distal of the flow restoring segment, and a capture segment distal the open segment. In use, a catheter is inserted into a selected blood vessel until a distal end of the catheter is distal of an occlusive or stenotic lesion in the blood vessel. The multimode occlusion and stenosis treatment apparatus is inserted into the catheter, the flow restoring segment is aligned with the lesion, and the catheter is withdrawn relative to the apparatus until a distal end of the catheter is proximal of the flow restoring segment to thereby allow the flow restoring segment to expand radially and compress the lesion against an inner surface of the blood vessel.
