Abstract

Devices, systems, and methods for treating a heart of a patient may make use of structures which limit a size of a chamber of the heart, such as by deploying a tensile member to bring a wall of the heart toward (optionally into contact with) a septum of the heart. The implant may include an electrode or other structure for applying pacing signals to one or both ventricles of the heart, for defibrillating the heart, for sensing beating of the heart or the like. A wireless telemetry and control system may allowing the implant to treat congestive heart failure, monitor the results of the treatment, and apply appropriate electrical stimulation.

Claims

1. An implant for treating a heart, the heart having a first chamber bordered by a septum and a wall, the heart having a second chamber separated from the first chamber by the septum, the implant comprising:

a first anchor coupleable to the septum;

a second anchor coupleable to the wall so that the second anchor contacts an epicardial tissue of the wall;

a tensile member coupleable to the first anchor and the second anchor so as to engage the septum and the wall such that the wall contacts the septum and is secured relative thereto;

a pacing electrode, defibrillating electrode, and/or sensing surface coupled with the second anchor to apply signals to the epicardial surface tissue of the wall; and

a signal transmission conductor near at least one of the anchors and coupled to the surface to allow heart signal transmission between the implant and a tissue of the heart.

2. The system of claim 1, wherein the surface comprises a pacing and/or beat sensing electrode surface, and further comprising insulation for isolating pacing and/or beat sensing signals from adjacent heart tissue.

3. The system of claim 2, further comprising a conductor extending along at least a portion of the tensile member, the insulation disposed at least in part between the tensile member and conductor.

4. The system of claim 1, further comprising an electrode surface along the second anchor such that the electrode surface contacts the epicardial surface of the wall.

5. The system of claim 4, further comprising a defibrillator signal source coupled with the electrode surface.

6. The system of claim 1, further comprising a heartbeat sensing lead, wherein a conductor included in the lead and the lead having a length sufficient to extend from adjacent one of the anchors to a contractile tissue when the implant is deployed, and further comprising a heartbeat monitoring signal processor coupled with the surface.

7. The system of claim 1, further comprising a first pacing lead, wherein a conductor included in the first lead and the first lead having a length sufficient to extend from adjacent one of the anchors to a contractile tissue when the implant is deployed, and further comprising:

a second pacing lead; and

a biventricular pacing signal source coupled with the first and second leads.

8. The system of claim 7, wherein the implant has a sensing mode and another mode, the implant in the sensing mode configured for transmitting output signals indicating beating of the heart to the processor, the implant in the other mode configured for pacing the heart or defibrillating the heart.

9. The system of claims 1, further comprising a signal source and/or signal processor wirelessly coupled with the electrode surface.
