Abstract: A cutting balloon catheter including a balloon mounted on a distal portion of a catheter shaft. The balloon includes a cutting member mounted on an exterior surface of the balloon which includes one or more features for providing the cutting member with enhanced flexibility for navigating tortuous anatomy and more closely conforms to the expansion characteristics of the balloon to which the cutting member is mounted.

Abstract: A medical device assembly for incising a stenosis in a blood vessel which includes an incising device, a tubular sheath, and a catheter having an inflatable balloon mounted thereon. The incising device includes a self-expanding scaffold having a plurality of cutting elements projecting radially outward therefrom, and an elongate member extending proximally from the self-expanding scaffold to be manipulated by a user. The self-expanding scaffold is positionable in the lumen of the sheath in a contracted configuration and deployed out of the lumen of the sheath to permit the self-expanding scaffold to expand to an expanded configuration. The inflatable balloon of the catheter is configured to be advanced distally into an interior of the self-expanding scaffold through a proximal opening of the self-expanding scaffold, and inflation of the inflatable balloon urges the cutting elements radially outward to incise a stenosis.
