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.
Claims19
Apparatus for treating occlusions and stenoses in body cavities, comprising an elongated flexible hollow catheter having a proximal end and a distal end provided with an internal anvil;
- an elongated flexible probe received in said catheter and having a proximal end and a distal end including a hammer adjacent said internal anvil;
- and means for imparting to said probe movements to cause said hammer to repeatedly strike against the anvil, including alternating reciprocatory movements into and completely out of contact with the anvil, and to thereby drive the distal end of the catheter deeper into the body cavity into which the distal end of the catheter is inserted.
