Abstract
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.
