    摘要： A miniature cross stream thrombectomy catheter useful in small blood vessel thrombectomy procedures. An annulus near the distal end of the miniature cross stream thrombectomy catheter is formed between a hypo-tube and a proximally directed bore of a concentrically aligned flow director whereby jet orifices in the hypo-tube communicate with the annulus to direct jet flows of saline or other fluid around and about the annulus and to be directed proximally from the annulus to pass through one or more outflow orifices and thence to pass through one or more inflow orifices thereby creating an ablation flow therebetween which loosens and carries away thrombotic materials from the walls of a blood vessel.

    摘要： A single operator exchange fluid jet thrombectomy method employing a single operator exchange fluid jet thrombectomy device having an outer catheter assembly and separable and exchangeable components in the form of an inner catheter assembly allowing functioning as a rheolytic thrombectomy catheter or as a crossflow thrombectomy catheter. The outer catheter assembly is common to any mode of usage and includes a guide catheter having a lumen through which a guidewire and the greater portion of a hypo-tube carrying a jet emanator and a flow director are passed and advanced. In the method, thrombus is dislodged, entrained, and broken into pieces by fluid jets and evacuated through the lumen of the guide catheter.

Embodiments include an outer catheter assembly common to any mode of usage having a guide catheter having a lumen through which a guidewire and the greater portion of a hypo-tube carrying a flow director are passed and advanced. For use as a rheolytic thrombectomy catheter, thrombus is dislodged, entrained, and broken into pieces by jets and evacuated through the lumen of the guide catheter. For use as a crossflow thrombectomy catheter, a flow director having outflow and inflow orifices is provided.

    摘要： A direct stream hydrodynamic catheter system is provided for the removal of thrombus, lesions and the like including provisions for the infusion of drugs, lysing fluids and the like into a blood vessel. Physician controlled high powered direct fluid jet streams emanate from a fluid jet emanator in the form of robust radially directed fluid jet streams to impinge upon and ablate difficult and strong thrombus or lesions within a blood vessel. Effluent aspiration is controlled by an exhaust regulator in the form of a roller pump, but effluent removal can be assistingly influenced by the fluid pressure associated with the radially directed fluid jet streams.
