METHOD FOR ACCESSING THE CORONARY MICROCIRCULATION AND PERICARDIAL SPACE

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.
