Consolidated atherectomy and thrombectomy catheter

An atherectomy system comprising:

• a catheter body extending from a proximal catheter portion to a distal catheter portion, the catheter body including an aspiration lumen extending from the distal catheter portion to the proximal catheter portion;
• an atherectomy assembly coupled with the distal catheter portion, the atherectomy assembly includes:
• a rotatable cutter, and
• a drive shaft coupled with the rotatable cutter and extending to the proximal catheter portion;
• a shaft sleeve extending through the aspiration lumen and surrounding the drive shaft, the draft shaft is rotatable relative to the shaft sleeve, and the shaft sleeve isolates the drive shaft from the aspiration lumen;
• a jet body positioned within the aspiration lumen near the catheter distal portion, the jet body includes at least one jet orifice directed proximally through the aspiration lumen;
• and
• an inflow orifice extending through the catheter body and in communication with the aspiration lumen, the inflow orifice is adjacent to and downstream from the jet body.

A method for identifying and removing one or more of plaques or thrombus from a vessel comprising:

• delivering a catheter including an atherectomy system coupled with a thrombectomy system to a location within the vessel including one or more of plaque or thrombus along a vessel wall;
• conducting a thrombectomy procedure with the thrombectomy system including:
• delivering a cyclical flow of infusion fluid through outflow and inflow orifices along a catheter body at the location and hydrodynamically removing thrombus, and
• entraining the removed thrombus in the cyclical flow and delivering the thrombus along an aspiration lumen of the catheter body;
• examining the location and determining the location of a plaque along the vessel wall after thrombus is removed, the thrombectomy procedure clarifying the location for examination;
• and
• conducting an atherectomy procedure with the atherectomy system at the clarified location including:
• rotatably cutting the plaque with a rotatable cutter, the rotatable cutter coupled with the catheter body, and
• delivering the cut plaque into the aspiration lumen with the cyclical flow of infusion fluid through the outflow and inflow orifices.
