摘要： A catheter which includes a cutting element (4B) having one or more raised (26B) elements is provided. The cutting element has a cup- shaped surface at the distal end that may be smooth and continuous except for the raised elements. The raised elements have a curved surface (30B) that is adapted to redirect cut particles of material when said curved surface is rotated so that a fluid vortex directing said cut particles towards one or more of the axis of rotation of the cutting element, the catheter axis, or a particle collection chamber is created. In further aspects of the invention, a cutting element oscillates in a direction roughly parallel to the axis of rotation of the cutting element.

摘要： A catheter having a tubular body and a rotatable shaft disposed within a lumen of the tubular body. A cutting element is coupled to the rotatable shaft, the cutting element having a cutting edge, the cutting element and rotatable shaft being longitudinally moveable within the tubular body between a stored position in which the cutting element is positioned distal of a side opening and a cutting position in which the cutting element is contained within the lumen of the tubular body and longitudinally aligned with the side opening. The cutting element is configured to extend through the side opening and to cut material from the wall of a vessel at a treatment site as the catheter is pulled proximally through the treatment site. The catheter may optionally have a rotating distal tip with an abrasive surface. The catheter includes a collection chamber positioned proximally of the cutting window.

摘要： The present invention provides an atherectomy catheter which has a cutting element that is able to cut both soft tissue and hard tissue, and methods of cutting material from a blood vessel lumen using a rotating cutting element. The cutting element has a sharp cutting edge that surrounds a cup-shaped surface and at least one surface of abrasive material. The cup-shaped surface directs the cut material into a tissue chamber. The cutting edge and the cup-shaped surface together are well suited to cut and remove relatively soft tissue from the blood vessel. The abrasive material surface in combination with the cutting element is well suited to abrade and remove hard material from the blood vessel.
