ABSTRACT:
Apparatus for eliminating or reducing occlusions or stenoses in veins and other body cavities has an elongated catheter with an ellipsoidal distal end having an internal anvil cooperating with a reciprocable hammer at the distal end of a flexible probe to drive the distal end of the catheter into an occlusion or into a stenoses. The proximal end of the probe is connected to the output element of a reciprocating unit which can be combined with a device for rotating the probe and/or the catheter. The distal end of the probe can be provided with an extension which projects beyond the hammer and beyond the distal end of the catheter to act upon a stenosis or upon an occlusion ahead of the distal end of the catheter.
