<p><P>PROBLEM TO BE SOLVED: To provide a method and apparatus for removing emboli from within the carotid arteries during interventional procedures that reduce the risk that emboli are carried into the cerebral vasculature. <P>SOLUTION: The method and apparatus 30 are provided for removing emboli during an angioplasty, stenting, or surgical procedure comprising a catheter 31 having an occlusion element 32, an aspiration lumen, and a blood outlet port in communication with the lumen, a guide wire 35 having a balloon 36, a venous return catheter with a blood inlet port, and tubing that couples the blood outlet port to the blood inlet port. A blood filter, a flow sensor, a flow control valve, and/or a pump may also be included in-line with the tubing to better facilitate filtering of emboli from blood reperfused into the patient and to better monitor and control the quantity of flow reversal. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
