Rotating occlusion treatment system

An occlusion treatment system comprising:

• a fluid suction and supply device;
• a catheter including a body portion having proximal and distal ends;
• and
• a debriding mechanism configured and dimensioned for axial movement through the catheter such that the debriding mechanism is extendable beyond the distal end of the body portion of the catheter, the debriding mechanism including a rotatable torque sleeve, and a head assembly operatively connected to the torque sleeve such that rotation of the torque sleeve causes corresponding rotation of the head assembly, the head assembly including a debriding tip having an outer surface with at least one aperture formed therein, the debriding mechanism being in fluid communication with the fluid suction and supply device such that debris created during debriding of the occlusion is aspirated from the lumen through the torque sleeve.

A method of treating a lumen at least partially blocked by an occlusion, the method comprising the steps of:

• positioning a catheter within the lumen;
• advancing a debriding mechanism through the catheter such that a debriding tip of the debriding mechanism is positioned adjacent the occlusion;
• effecting rotation of the debriding tip, whereby a debriding member on an outer surface of the debriding tip debrider the occlusion, and directs debris from the occlusion through a corresponding aperture in the outer surface of the debriding tip;
• and
• aspirating the debris through the debriding mechanism to remove the debris from the lumen.
