Method and system for nerve stimulation and cardiac sensing prior to and during a medical procedure
First Claim
1. A method of performing a medical procedure, comprising:
- providing a first electrode for supplying electrical current;
positioning the first electrode adjacent a vagal nerve;
providing a second electrode for supplying electrical current;
positioning the second electrode adjacent a phrenic nerve;
supplying electrical current to the first electrode to stimulate the vagal nerve to control heart rate; and
supplying electrical current to the second electrode to stimulate the phrenic nerve to control breathing, wherein the supplying of electrical current to the first and second electrodes is coordinated.

Abstract
A method of performing a medical procedure, such as surgery, is provided. A nerve is stimulated in order to adjust the beating of the heart to a first condition, such as a stopped or slowed condition. The medical procedure is performed on the heart or another organ. The stimulation of the nerve is stopped in order to adjust the beating of the heart to a second condition, such as a beating condition. The heart itself may also be stimulated to a beating condition, such as by pacing. The stimulation of the nerve may be continued in order to allow the medical procedure to be continued. A sensor to sense a characteristic of a fluid or tissue, such as an impending contraction, may be also used during the medical procedure. Systems and devices for performing the medical procedure are also provided.
