1. A cutting dilation balloon comprising:
- a balloon body having an outer surface;
at least one ultrasonic microscalpel operatively disposed relative to the outer surface of the body, at least a portion of the at least one microscalpel including a coating comprising a thin-film transducer; and
a source of power, the at least one microscalpel being operatively disposed relative to the source of power so as to be controllably activatable, the power source being a source of ultrasonic energy and providing oscillatory, thermal, RF, electric energy, or a combination of these, to the at least one microscalpel, the at least one microscalpel being ultrasonically activatable by the provision of the thin film transducer.

Abstract
The present invention provides a catheter balloon, and balloon catheter incorporating the catheter balloon, useful in medical dilation procedures. The catheter balloon includes at least one microscalpel operatively disposed on an outer surface thereof. The microscalpel may advantageously be operatively disposed relative to a power source so as to be controllably activatable. Also provided are methods of making the inventive balloon and/or catheter as well as methods of using the inventive catheter in a dilation/incising treatment.

12. A cutting balloon catheter comprising:
-
an elongated catheter shaft having a proximal end, a distal end, and an inflation lumen extending through at least a section thereof; a cutting dilation balloon comprising a balloon body having an outer surface and an interior in fluid communication with the inflation lumen; at least one ultrasonic microscalpel operatively disposed relative to the out surface of the body, at least a portion of the at least one microscalpel including a coating comprising a thin-film transducer; and a source of power, the at least one microscalpel being operatively disposed relative to the source of power so as to be controllably activatable, the power source being a source of ultrasonic energy and providing oscillatory, thermal, RF, electric energy, or a combination of these, to the at least one microscalpel, the at least one microscalpel being ultrasonically activatable by the provision of the thin film transducer. - View Dependent Claims (13)

14. A method for incising a stenosis comprising the steps of:
-
providing a balloon catheter, comprising; an elongated catheter shaft having an inflation lumen extending through at least a portion thereof; a balloon having an interior, an outer surface, and at least one ultrasonic microscalpel operatively disposed on the outer surface, wherein the interior of the balloon is in fluid communication with the inflation lumen, at least a portion of the at least one ultrasonic microscalpel including a coating comprising a thin-film transducer, a source of power, the at least one microscalpel being operatively disposed relative to the source of power so as to be controllably activatable, the power source being a source of ultrasonic energy and providing oscillatory, thermal, RF, electric enemy, or a combination of these, to the at least one microscalpel, the at least one microscalpel being ultrasonically activatable by the provision of the thin film transducer; inserting the balloon catheter into the bodily lumen and directing the balloon to the site to be dilated; and inflating the balloon so that at least one microscalpel at least partially incises the stenosis. - View Dependent Claims (15, 16)
