ABSTRACT:
A device for incising and dilating a stenosis in a vessel of a patient includes a dilator housing and a plurality of blades which can be selectively extended from the housing. Specifically, the housing is formed to surround a chamber and the chamber contains an inflatable balloon. The plurality of blades are mounted on the inflatable balloon and pass through slits in the housing. The housing is attached to a placement catheter which includes a lumen for inflating and deflating the balloon. In the operation of the device, the balloon is selectively inflated within the chamber to move the device between a retracted and an expanded configuration. In the retracted configuration, the balloon is deflated and the blades are withdrawn into the housing and the housing is used as a dilator. In the expanded configuration, the balloon is inflated and the blades are extended through the slits in the housing and the device is used as an incisor.
