Abstract: A blood vessel access closure device includes an inner blood vessel wall support member and an outer blood vessel wall support member. The closure device also includes a deployment member and an electrode. The deployment member is configured to draw the inner and outer blood vessel wall support members towards each other when the inner and outer blood vessel wall members are deployed on opposite sides of a blood vessel wall during closure of a hole in the blood vessel wall. The electrode is configured to be attached to the deployment member and configured to be used to measure impedance.

Abstract: The present invention is directed to a method and apparatus for removing thrombus and plaque from a coronary artery which is at least partially occluded due to deposits of plaque and thrombus on the inner wall of the artery. More particularly, the invention provides a treatment method and apparatus for the same, wherein a balloon catheter and coronary thrombectomy catheter are inserted into an at least partially occluded coronary artery. The coronary thrombectomy catheter with the balloon catheter are placed upstream from the occluded area. A balloon at the distal end of the balloon catheter is inflated, expanding the distal end of the coronary thrombectomy catheter. The balloon is then deflated, the distal tip of the guide catheter retaining its expanded shape. The balloon is deflated and extended beyond the occluded portion of the artery.
