A method and apparatus for anchoring of pacing leads

摘要

A pacemaker lead ( 18 ) is implanted by using a two anchor system. One anchor ( 916 ) to first secure the position of an introducer ( 14 ) through which the pacemaker lead will be implanted, and a second anchor ( 20 ) used for implanting the distal tip of the pacemaker lead ( 18 ). Examples of the anchors included various types of mechanical anchors or mechanical anchor combinations such as a suction anchor, a barbed needle, or a needle and balloon combination. The anchors can be used in the pericardial space in the heart by disposing an elongate instrument into the venous system of the heart; puncturing the venous system at a predetermined position; disposing the elongate instrument into the pericardial space at a predetermined location in the pericardial space; and implanting a pacemaker lead at the predetermined position.
