Abstract
A medical instrument which is insertable into a vascular system to incise a stent embedded within a stenosis is provided herein and includes a multi-luminal catheter with a distal expandable balloon mounted with a reciprocating cutting member. The cutting member is selectively activated by an external reciprocating mechanism which is transmitted through the catheter to the cutting member mounted on the balloon's surface. The cutting member is designed to have the characteristics necessary to cut the metallic struts of a stent. In operation, the device is placed within the stenosis having an embedded stent and the expandable balloon is inflated. Preferably, the cutting member will be facing the myocardium. Then reciprocating motion is activated and the cutting member proceeds to sever the struts of the stent and make an incision in the stenosis. It is anticipated that more than one cutting member may be mounted on the balloon's surface.
