Abstract
A cardiac lead system is provided. The lead is placed epicardially through the transverse pericardial sinus with integrated curvatures to prevent the lead from slipping out of the transverse pericardial sinus. Interaction with multiple chambers of the heart is facilitated in a single lead, without anchors that embed into the heart wall. Multiple electrodes can be grouped over each targeted heart area to ensure adequate electrical contact.
Claims22
An elongate lead device sized and shaped to pass through a transverse pericardial sinus of a heart, comprising:
- a lead body, including:
- a longitudinal axis;
- a proximal-most end and an opposing distal end;
- a first longitudinal side edge boundary and a second longitudinal side edge boundary;
- a first zone having one or more first zone electrodes providing a first electrical energy within the transverse pericardial sinus in a deployed state;
- and
- a positioning element including one or more curvatures provided intermediate the first zone and the distal end, closer to the distal end than the first zone, wherein the positioning element is contiguous with the lead body from a beginning to an end of the one or more curvatures and is free of any electrodes, such that the leady body is free of any electrodes intermediate the positioning element and the distal end and intermediate the one or more first zone electrodes and the distal end, and wherein the one or more curvatures extend out transverse from the longitudinal axis beyond at least one of the first or second longitudinal side edge boundaries.
A heart treatment system, comprising:
- an elongate lead device sized and shaped to pass through a transverse pericardial sinus of the heart and including a longitudinal axis, a first longitudinal side edge length, a second longitudinal side edge length, a proximal-most end, a distal end opposite the proximal-most end, a first zone, and a positioning element, wherein:
- the first zone includes one or more first zone electrodes providing a first electrical energy,
- the one or more curvatures extend out transverse from the longitudinal axis beyond at least the first or the second longitudinal side edge lengths,
- the positioning element includes one or more curvatures, is contiguous with the elongate lead device, and is free of any electrodes from a beginning to an end of the one or more curvatures, and
- the elongate lead device is free of any electrodes intermediate the one or more first zone electrodes and the distal end.
