Claim Text:
1. An occlusion treatment device configured and dimensioned for treatment of a lumen at least partially blocked by an occlusion, the occlusion treatment device comprising: a catheter including a body portion having proximal and distal ends; at least one expandable element secured to the body portion of the catheter, the at least one expandable element being expandable within the lumen to define a radial dimension; and a material removal element configured to extend distally from the distal end of the body portion and including a flexible debriding member having a free distal end configured and dimensioned to contact the occlusion, wherein a maximum exposed distal portion of the material removal element defines a length less than the radial dimension in order to restrict contact between the flexible debriding member and an inner wall of the lumen, and being in communication with an energy source to facilitate selective energizing of the flexible debriding member, the catheter being dimensioned to be axially movable through the lumen, and rotatable within the lumen, such that the material removal element selectively imparts at least one of a non-mechanical energy and a mechanical energy to the occlusion to effect debriding of the occlusion.
