| description | PROBLEM TO BE SOLVED: To provide a catheter and system for removing a cross current thrombus from a blood vessel or other lumina in the body by breaking the thrombus or other materials. SOLUTION: A high speed jet of saline solution ejected from a circular loop- shaped jet generator (46) or other jet generator located at the distal end (38) of a catheter accompanies fluid into a flow-in opening (34) and generates a cross current jet (82) eddying in the direction of ejection through a flow-out opening (30) with the backing pressure created by the flow resistance of the fluid. By applying he vertical force and resistance of the fluid to a thrombotic deposit or a focus lesion (78) in a blood vessel (76) or in other lumina in the body, the thrombotic deposit or focus lesion is broken to pieces and particles of the thrombus are accompanied into the flow-in opening (34). The particles of the thrombus soaked and softened in the high speed jet either pass through a discharge lumen or recycle by way of a flow-out opening (32). |
