Abstract:
1. An atherectomy and thrombectomy 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 thrombectomy assembly coupled with the distal catheter portion, the thrombectomy assembly is operable in atherectomy and thrombectomy configurations, the thrombectomy assembly includes: in the thrombectomy configuration a cyclical flow is generated by the jet body through the outflow and inflow orifices to hydrodynamically abrade thrombus, the cyclical flow entrains thrombus and delivers thrombus into the aspiration lumen; and in the atherectomy configuration the rotatable cutter cuts plaque into plaque particulate, and the cyclical flow entrains the plaque particulate and delivers the plaque particulate into the aspiration lumen.
