Abstract
Pacemakers and pacemaker delivery systems and methods are disclosed which use a modified cylindrical pacemaker body having a flat side which includes the anode/cathode and spikes to anchor the pacemaker in place within the pericardium.
Claims31
A pacemaker device, comprising:
- a cylindrical shell having a first end and a second end, and an elongated flattened side which extends from the first end to the second end;
- and
- a flat electrode surface positioned on the flattened side, and functioning as a cathode to the pacemaker device.
A pacemaker delivery assembly, comprising:
- an elongated cannula;
- an insertion tool positionable within the cannula and having a holder portion;
- and
- a pacemaker positionable within the cannula, adapted to engage with the holder portion of the insertion tool, and comprising:
- a cylindrical shell having a first end and a second end, and an elongated flattened side which extends from the first end to the second end.
2 more elements
A method of inserting a pacemaker, comprising:
- threading a string around a pulley on one end of the pacemaker;
- mounting the pacemaker on a first end of an insertion tool;
- reversibly attaching both ends of the string to a second end of the insertion tool;
- and
- inserting the insertion tool and pacemaker within a cannula to deliver to a target location on an epicardial surface.
