Abstract
Devices and methods can be used for artificial cardiac pacing and/or resynchronization. For example, this document provides improved electrodes for stimulating and sensing electrical activity of the heart, and provides pacing and resynchronization systems incorporating such electrodes. While the devices and methods provided herein are described primarily in the context of pacing, it should be understood that resynchronization can additionally or alternatively be performed in an analogous manner, and that the scope of this disclosure includes such subject matter.
Claims20
A cardiac pacing device comprising:
- a first flange portion;
- a second flange portion;
- a central portion extending between and connecting the first flange portion and the second flange portion;
- and
- one or more pacing electrodes exposed on an inward-facing surface of the first flange portion that faces the second flange portion.
A method of treating a human heart, wherein the method comprises implanting a pacing device in the heart, wherein the pacing device comprises:
- a first flange portion;
- a second flange portion;
- a central portion extending between and connecting the first flange portion and the second flange portion;
- and
- one or more pacing electrodes exposed on an inward-facing surface of the first flange portion that faces the second flange portion,
- wherein the first flange portion is disposed in a first heart chamber, the second flange portion is disposed in a second heart chamber that differs from the first heart chamber, and the central portion is disposed in a septal wall separating the first heart chamber from the second heart chamber.
A method of treating a human heart, wherein the method comprises implanting a pacing device in the heart, wherein the pacing device comprises:
- a first flange portion;
- a second flange portion;
- a central portion extending between and connecting the first flange portion and the second flange portion;
- and
- one or more pacing electrodes exposed on an inward-facing surface of the first flange portion that faces the second flange portion,
- wherein the first flange portion is disposed in a first heart chamber, the second flange portion is disposed in a pericardial cavity, and the central portion is disposed in a myocardium separating the first heart chamber from the pericardial cavity.
A method of treating a human heart, wherein the method comprises implanting a pacing device in the heart, wherein the pacing device comprises:
- a first flange portion;
- a second flange portion;
- a central portion extending between and connecting the first flange portion and the second flange portion;
- and
- one or more pacing electrodes exposed on an inward-facing surface of the first flange portion that faces the second flange portion,
- wherein the first flange portion is disposed in an atrial appendage of the heart, the second flange portion is disposed in a ventricular outflow tract of the heart, and the central portion is disposed in a myocardium separating the appendage from the outflow tract.
