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.
Claims48
A method of performing a coronary bypass procedure, comprising:
- stimulating a nerve using endotracheal stimulation to adjust beating of a heart to a first condition;
- performing a first anastomosis of the coronary bypass procedure when the beating of the heart has been adjusted to the first condition;
- reducing stimulation of the nerve to adjust beating of the heart to a second condition;
- stimulating the nerve a subsequent time in order to re-adjust beating of the heart to the first condition;
- and
- performing a second anastomosis of the coronary bypass procedure when the beating of the heart has been re-adjusted to the first condition.
A system for performing a medical procedures comprising:
- a nerve stimulator to inhibit beating of a heart;
- a cardiac stimulator to stimulate beating of the heart;
- means for coordinated regulation of output from the nerve stimulator and output from the cardiac stimulator;
- and
- drug delivery means for delivering at least one drug during the medical procedure.
A method of performing a medical procedure, comprising:
- providing a stent device;
- stimulating a nerve to adjust beating of a heart to a first condition;
- delivering the stent device to the heart when the beating of the heart has been adjusted to the first condition;
- and
- reducing stimulation of the nerve to adjust beating of the heart to a second condition.
A method of performing a coronary bypass procedure, comprising:
- stimulating a nerve using endoesophageal stimulation to adjust beating of a heart to a first condition;
- performing a first anastomosis of the coronary bypass procedure when the beating of the heart has been adjusted to the first condition;
- reducing stimulation of the nerve to adjust beating of the heart to a second condition;
- stimulating the nerve a subsequent time in order to re-adjust beating of the heart to the first condition;
- and
- performing a second anastomosis of the coronary bypass procedure when the beating of the heart has been re-adjusted to the first condition.
