Abstract
A device for incising tissue to a pre-selected incision depth within a body conduit of a patient includes an elongated balloon catheter and at least one elongated straight blade that is mounted on the balloon. To control the incision depth, each blade has a blunt section formed with a non-incising surface and a cutting edge positioned distally to the blunt section. A proximal portion of the blade is attached to a proximal balloon section, and in operation, the balloon/blade combination is advanced into the body conduit and positioned distal to the target tissue/stenosis. The balloon is then inflated. With this inflation, the blade is inclined relative to the axis of the catheter with an increasing distance between the blade and the axis in a distal direction. The device is then withdrawn, proximally, to incise the tissue/stenosis.
