Abstract

A system of performing a medical procedure, such as surgery, is provided. The system comprises a compression member for compressing a body portion and a means for controlling the compression. Methods and devices for performing the medical procedure are also provided.

Claims

1. A system for controlling blood flow to a target area during a medical procedure comprising:

at least one compression member to cover a body portion comprising at least one limb, the compression member including a vessel harvesting opening, wherein the vessel harvesting opening is positioned on the compression member so that a blood vessel of a limb may be harvested through the vessel harvesting opening;

a means to sense intermittent cardiac asystole; and

a control unit to activate compression of the compression member, wherein the control unit activates compression of the compression member in response to intermittent cardiac asystole.

2. The system of claim 1 wherein the blood vessel is a saphenous vein.

3. A system for controlling blood flow during a medical procedure comprising:

at least one compression member to cover at least one limb portion, the compression member including a plurality of body limb openings;

a means to sense intermittent cardiac asystole; and

a control unit to activate compression of the compression member, wherein the control unit activates compression of the compression member in response to intermittent cardiac asystole.

4. The system of claim 3 wherein the compression member covers a limb of a patient selected from the group consisting of an arm and a leg.

5. The system of claim 3 wherein the medical procedure is selected from the group consisting of:

a surgical procedure, a non-surgical procedure, a fluoroscopic procedure, a cardiac procedure, a vascular procedure, a neurosurgical procedure, an electrophysiological procedure, a diagnostic procedure, a therapeutic procedure, an ablation procedure, an endovascular procedure, a liver procedure, a spleen procedure, a pulmonary procedure, an aneurysm repair, an imaging procedure, a CAT scan procedure, a MRI procedure, a pharmacological therapy, a drug delivery procedure, a biological delivery procedure, a genetic therapy, a cellular therapy, a cancer therapy, a radiation therapy, a transplantation procedure, a coronary angioplasty procedure, a stent delivery procedure, an atherectomy procedure, a procedure that requires precise control of cardiac motion, a procedure that requires precise control of bleeding, a non-invasive procedure, a minimally invasive procedure, an invasive procedure, a port-access procedure, an endoscopic procedure, a sternotomy procedure, a thoracotomy procedure and a robotic procedure.

6. The system of claim 3 further comprising a cardiac stimulator to adjust the beating of the heart.

7. The system of claim 3 further comprising a nerve stimulator to adjust the beating of the heart.

8. A compression system for controlling blood flow during a medical procedure, comprising:

at least one compression member to cover at least one limb, the compression member including a plurality of limb openings;

a control unit coupled to the compression member to activate compression of the compression member, wherein the control unit activates compression of the compression member intermittently during the medical procedure; and

a nerve stimulator in communication with the control unit, wherein the nerve stimulator stimulates a vagal nerve intermittently to adjust the beating of a heart, wherein the control unit activates compression of the compression member in response to vagal nerve stimulation.

9. The system of claim 8 wherein the compression member further comprises a vessel harvesting opening.

10. The system of claim 8 wherein the compression member covers a limb of a patient selected from the group consisting of an arm and a leg.

11. The system of claim 8 wherein the medical procedure is selected from the group consisting of:

a surgical procedure, a non-surgical procedure, a fluoroscopic procedure, a cardiac procedure, a vascular procedure, a neurosurgical procedure, an electrophysiological procedure, a diagnostic procedure, a therapeutic procedure, an ablation procedure, an endovascular procedure, a liver procedure, a spleen procedure, a pulmonary procedure, an aneurysm repair, an imaging procedure, a CAT scan procedure, a MRI procedure, a pharmacological therapy, a drug delivery procedure, a biological delivery procedure, a genetic therapy, a cellular therapy, a cancer therapy, a radiation therapy, a transplantation procedure, a coronary angioplasty procedure, a stent delivery procedure, an atherectomy procedure, a procedure that requires precise control of cardiac motion, a procedure that requires precise control of bleeding, a non-invasive procedure, a minimally invasive procedure, an invasive procedure, a port-access procedure, an endoscopic procedure, a sternotomy procedure, a thoracotomy procedure and a robotic procedure.

12. The system of claim 8 wherein the nerve stimulator stimulates the vagal nerve to stop beating of the heart.

13. The system of claim 8 wherein the nerve stimulator comprises at least one electrode.
