RELEASABLE GUIDE AND METHOD FOR ENDOSCOPIC CARDIAC LEAD PLACEMENT

摘要

Apparatus and surgical methods establish temporary suction attachment to a target site on the surface of a bodily organ for enhancing accurate placement of a surgical instrument maintained in alignment with the suction attachment. A suction port on the distal end of a supporting cannula provides suction attachment to facilitate accurate positioning of a needle for injection penetration of tissue at the target site of for anchoring a cardiac electrode on the moving surface of a beating heart. Force applied via the suction attachment to the surface of the heart selectively distorts the surface of the myocardium for angularly orienting and accurately positioning a surgical instrument or cardiac electrode thereon.
