ROTATING OCCLUSION TREATMENT SYSTEM

摘要

An occlusion treatment device for the treatment of a body lumen that is at least partially blocked by an occlusion. The occlusion treatment device includes a catheter and a debriding mechanism that is configured and dimensioned for axial movement through the catheter and is extendable beyond a distal end of the catheter. The debriding mechanism includes a head assembly with a debriding tip having an outer surface with at least one aperture formed therein, wherein at least one of the apertures is complemented by a corresponding debriding member that extends outwardly from the outer surface of the debriding tip and directs debris from the occlusion through the at least one aperture to facilitate removal of the debris from the lumen. The debriding mechanism is rotatable to effect debriding of the occlusion.
