Methods and apparatus for direct coronary revascularization

摘要

Described herein are methods and apparatus relating to a conduit placed in the heart wall between the left ventricle and the coronary artery. More particularly, the methods and apparatus accomplish one or more of the following goals, namely: (1) to accurately engage and align a conduit with the coronary artery; (2) to deliver a conduit into position in the heart wall; (3) to increase net forward flow through an opening or conduit from the left ventricle to the coronary artery; (4) to increase long term patency of a conduit between the left ventricle and coronary artery; (5) to accommodate wall thickness changes of the heart; and (6) to prevent migration of the conduit.
