Abstract
An enhanced cross stream mechanical thrombectomy catheter having a distal end with outflow and inflow orifices at one side for producing concentrated cross stream jet flow for selective and concentrated thrombus ablation during thrombectomy procedures. A multidirectional fluid jet emanator positioned within the distal catheter lumen comprises high velocity fluid jets which produce jet flow that is directed toward distal and proximal ends of the catheter. Jet flow directed toward the proximal end provides a region of low pressure near an inflow orifice which acts to pull thrombotic particulate from the vasculature. The invention provides for suitable distancing of high powered ablation or suction forces from the near walls of the vasculature. Cross stream flow emanating from one side of the catheter distal end urges the opposing non-orificed side of the catheter distal end toward and against the vascular wall to inhibit contact of the inflow orifice with the vascular wall.
