  • an inflatable balloon, said inflatable balloon defining an axis, having an external surface and being insertable into the vasculature of a patient for movement therein between a deflated configuration and an inflated configuration;

    a resilient base member mounted on said external surface of said balloon, said base member being substantially compliant with said external surface of said balloon during movement therewith; and

    a plurality of blade segments attached to said base member, with a portion of each said blade segment being juxtaposed with a portion of at least one other said blade segment and being axially off-set therefrom to allow relative movement therebetween during a movement of said balloon from said deflated configuration into said inflated configuration to embed at least one of said plurality of blade segments into the stenosis while said external surface of said balloon conforms with the stenosis and the vasculature of the patient.
