Abstract

An electro-stimulation device includes a pair of electrodes for connection to at least one location in the body that affects or regulates the heartbeat. The electro-stimulation device both electrically arrests the heartbeat and stimulates the heartbeat. A pair of electrodes are provided for connection to at least one location in the body that affects or regulates the heartbeat. The pair of electrodes may be connected to an intravenous catheter for transvenous stimulation of the appropriate nerve. In another aspect, the invention is directed to a method for arresting the beat of a heart in a living body comprising the steps of connecting the pair of electrodes to at least one location in the body that affects or regulates the heartbeat and supplying an electrical current to the electrodes of sufficient amplitude and duration to arrest the heartbeat.

Claims

1. A method for stimulating a phrenic nerve within a patient during a medical procedure, comprising:

advancing an array of electrodes through an organ to a point adjacent a phrenic nerve;

selectively employing electrodes within the array to direct electrical energy supplied to the electrodes to the phrenic nerve;

sensing a temperature change within the patient resulting from inspiration of outside air; and

supplying an electrical energy from a power supply to the selectively employed electrodes, wherein the electrical energy has a sufficient amplitude and duration to stimulate the phrenic nerve and thereby control the patient'"'"'s breathing during the medical procedure, wherein the medical procedure is a diagnostic procedure.

2. A method for stimulating a phrenic nerve within a patient during a medical procedure, comprising:

advancing an array of electrodes through an organ to a point adjacent a phrenic nerve;

selectively employing electrodes within the array to direct electrical energy supplied to the electrodes to the phrenic nerve;

supplying an electrical energy from a power supply to the selectively employed electrodes; and

synchronizing the supply of electrical energy to the selectively employed electrodes to a sensed temperature change wherein the electrical energy has a sufficient amplitude and duration to stimulate the phrenic nerve and thereby control the patient'"'"'s breathing during the medical procedure, wherein the organ is a blood vessel.

3. The method of claim 2 wherein the medical procedure is a therapeutic procedure.

4. The method of claim 2 wherein the medical procedure is a minimally-invasive surgical procedure.

5. The method of claim 2 wherein the medical procedure is an open-heart surgical procedure.

6. The method of claim 2 wherein the medical procedure is a coronary artery bypass graft procedure.

7. The method of claim 2 wherein the medical procedure is an endoscopic surgical procedure.

8. The method of claim 2 wherein the medical procedure is a minithorascopic surgical procedure.

9. The method of claim 2 further comprising a transvenous lead carrying the array of electrodes.

10. The method of claim 2 further comprising a switch for selectively employing electrodes within the array.

11. The method of claim 2 wherein the power supply is a pulse generator.

12. A method for stimulating a hypoglossal nerve within a patient, comprising:

advancing an array of electrodes through an organ to a point adjacent a hypoglossal nerve;

selectively employing electrodes within the array to direct electrical energy supplied to the electrodes to the hypoglossal nerve;

detecting an inspiratory phase of a respiration cycle of the patient; and

supplying an electrical energy from a power supply to the selectively employed electrodes, wherein the electrical energy has a sufficient amplitude and duration to stimulate the hypoglossal nerve, wherein the organ is a blood vessel.

13. The method of claim 12 further comprising a transvenous lead carrying the array of electrodes.

14. The method of claim 12 further comprising a switch for selectively employing electrodes within the array.

15. The method of claim 12 wherein the power supply is a pulse generator.

16. The method of claim 12 further comprising the step of synchronizing the supply of electrical energy to the selectively employed electrodes to the detected inspiratory phase of the respiration cycle.
