1. An atherectomy system for coring, ingesting and removing an obstruction from within a patient'"'"'s vessel, comprising in combination:
- a flexible guide-wire insertable into the vessel,a flexible rotary catheter, rotatably disposed and insertable into the vessel over said flexible guide-wire, having at its distal end a rotary coring means for making a circular cut in an obstruction located in front of it, and coupling means at its proximal end, and,a continuous passage, for ingesting the cored obstruction material, defined between said flexible rotary catheter and said flexible guide-wire, where the relative motion between said flexible rotary catheter and said flexible guide-wire assists in moving said ingested obstruction material proximally in said continuous passage.

Abstract
An atherectomy system for coring, ingesting and removing an obstruction from within a patient'"'"'s vessel, comprising a flexible guide-wire insertable into the vessel, a flexible rotary catheter being rotatably disposed and insertable into the vessel over the flexible guide-wire, having a rotary coring device at its distal end for making a ciruclar cut in an obstruction located in front of the rotary coring device, relative motion between the inner-wall and the flexible guide-wire mechanically enabling the ingested obstruction material into the catheter.

24. A process for removing an obstruction from an vessel with an atherectomy system, comprising the following steps:
-
inserting into a vessel, into an obstruction, a flexible guide-wire, advancing over the flexible guide-wire a rotary coring means located at a distal end of an atherectomy catheter, advancing and rotating the rotary coring means to the obstruction and coring the obstruction, mechanically assisting in moving the cored material proximally in a continuous passage defined between the atherectomy catheter and the flexible guide-wire, removing the atherectomy system containing the obstruction material out of the vessel. - View Dependent Claims (25)
