Abstract
An apparatus for incising a stenosis within a vascular conduit of a patient includes an inflatable balloon attached to an elongated catheter that defines a longitudinal axis. The distal end of the balloon includes a tapered section and at least one incising blade is attached to the tapered section. Each incising blade is oriented on the tapered section with the proximal end of the blade radially distanced from the longitudinal axis at a distance rand the distal end of the incising blade radially distanced from the longitudinal axis at a distance r. After the balloon has been inflated, each incising blade is oriented with r>rto position the incising blades at an angle relative to the axis. This cooperation of structure allows the incising blades to cut an incision into a stenosis during axial advancement of the inflated balloon.
