Method and system for nerve stimulation prior to and during a medical procedure
First Claim
1. A method for controllably stopping or slowing a heart intermittently during a medical procedure, comprising:
- providing a controllable nerve stimulator capable of automatically stopping stimulation of a vagal nerve, the nerve stimulator comprising a nerve stimulation electrode;
positioning the nerve stimulation electrode in a position suitable for stimulating a vagal nerve to stop or slow the heart;
controllably starting stimulation of the vagal nerve;
automatically stopping stimulation of the vagal nerve;
continuing to start and stop stimulation of the vagal nerve in order to stop or slow the heart intermittently during the medical procedure.

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. Systems and devices for performing the medical procedure are also provided.
