Patent ID: 8500788

Claim:
A system, for treating a patient's vessel, comprising: a catheter; an elongate body at least partially within the catheter and having a proximal portion with a proximal end, a distal portion with a distal end, and a lumen extending between the proximal end and the distal end; a stent, residing entirely within the elongate body in a compressed stent configuration and configured to be advanced relative to the elongate body, the stent having a distal section and a proximal section, the stent being configured to change between the compressed stent configuration and an expanded stent configuration; and at least one cutting member mounted directly to an outer surface of the catheter and being configured to increase a cross-sectional dimension of a lumen of the vessel in a stenotic region of the vessel, by dislodging plaque material in the stenotic region by moving rotationally relative to the stent, while the distal section remains engaged with, and rotationally fixed relative to, a wall of the vessel; wherein the distal section of the stent is configured to engage the wall and to change from a compressed distal configuration to an expanded distal configuration when advanced distal to the distal end of the elongate body; wherein the proximal section of the stent is configured to engage the wall and to change from a compressed proximal configuration to an expanded proximal configuration by advancing the stent relative to the elongate body; wherein, while the expanded distal section of the stent is engaged at the vessel wall, while the proximal section of the stent is retained by the elongate body, and while the at least one cutting member dislodges the plaque material, the distal section captures debris dislodged from the stenotic region by the at least one cutting member.
