Parasympathetic pacing therapy during and following a medical procedure, clinical trauma or pathology
View Patent ↗A treatment method is provided, including identifying a subject as one who is selected to undergo an interventional medical procedure, and, in response to the identifying, reducing a likelihood of a potential adverse effect of the procedure by applying an electrical current to a parasympathetic site of the subject selected from the group consisting of: a vagus nerve of the subject, an epicardial fat pad of the subject, a pulmonary vein of the subject, a carotid artery of the subject, a carotid sinus of the subject, a coronary sinus of the subject, a vena cava vein of the subject, a jugular vein of the subject, a right ventricle of the subject, a parasympathetic ganglion of the subject, and a parasympathetic nerve of the subject.
1. A treatment method, comprising:
identifying a subject as one who is selected to undergo an interventional medical procedure; and
in response to the identifying, reducing a likelihood of a potential adverse effect of the procedure, wherein the potential adverse effect is postoperative atrial fibrillation, by applying an electrical current to a parasympathetic site of the subject selected from the group consisting of: a vagus nerve of the subject, an epicardial fat pad of the subject, a pulmonary vein of the subject, a carotid artery of the subject, a carotid sinus of the subject, a coronary sinus of the subject, a vena cava vein of the subject, a jugular vein of the subject, a right ventricle of the subject, a parasympathetic ganglion of the subject, and a parasympathetic nerve of the subject,
wherein applying the current comprises commencing applying the current after the subject concludes undergoing the procedure.
2. The method according to claim 1 , wherein the postoperative atrial fibrillation includes an immune-mediated response to the procedure, and wherein applying the current comprises configuring the current to reduce the likelihood of the immune-mediated response.
3. The method according to claim 1 , wherein applying the current comprises commencing applying the current within the first 7 days after the subject concludes undergoing the procedure.
4. The method according to claim 1 , wherein the interventional procedure includes a heart procedure, and wherein identifying the subject comprises identifying the subject as one who is selected to undergo the heart procedure.
5. The method according to claim 4 , wherein applying the current comprises configuring the current to reduce mechanical stress of the heart.
6. The method according to claim 4 , wherein applying the current comprises configuring the current to reduce a heart rate of the subject.
7. The method according to claim 4 , wherein applying the current comprises configuring the current to improve coronary blood flow of the subject.
8. The method according to claim 4 , wherein the heart procedure includes coronary bypass surgery, and wherein identifying the subject comprises identifying the subject as one who is selected to undergo the coronary bypass surgery.
9. The method according to claim 8 , wherein applying the current comprises configuring the current to reduce a likelihood of graft failure.
10. The method according to claim 8 , wherein applying the current comprises configuring the current to reduce a likelihood of a reduction of peripheral blood flow.
11. The method according to claim 4 , wherein the heart procedure includes carotid endarterectomy, and wherein identifying the subject comprises identifying the subject as one who is selected to undergo the carotid endarterectomy.
12. The method according to claim 11 , wherein applying the current comprises configuring the current to reduce a likelihood of restenosis.
13. The method according to claim 1 , wherein the interventional procedure includes a surgical procedure, and wherein identifying the subject comprises identifying the subject as one who is selected to undergo the surgical procedure.
14. The method according to claim 13 , wherein the surgical procedure includes a surgical heart procedure, and wherein identifying the subject comprises identifying the subject as one who is selected to undergo the surgical heart procedure.
15. The method according to claim 13 , wherein the interventional procedure includes an abdominal surgical procedure, and wherein identifying the subject comprises identifying the subject as one who is selected to undergo the abdominal surgical procedure.
16. The method according to claim 15 , wherein applying the current comprises configuring the current to reduce a likelihood of a complication selected from the group consisting of: stenosis of gastrointestinal (GI) tract segments involved in the surgical procedure, GI stasis, and flare of inflammatory disease.
17. The method according to claim 13 , wherein the interventional procedure includes transplantation of tissue selected from the group consisting of: an organ and cells, and wherein identifying the subject comprises identifying the subject as one who is selected to undergo the transplantation of the selected tissue.
18. The method according to claim 13 , wherein the interventional procedure includes implantation of an implantable medical device, and wherein identifying the subject comprises identifying the subject as one who is selected to undergo the implantation of the device.
19. The method according to claim 13 , wherein the interventional procedure includes a heart transplantation procedure, and wherein identifying the subject comprises identifying the subject as one who is selected to undergo the heart transplantation procedure.
20. The method according to claim 19 , wherein applying the current comprises concluding application of the current at least 2 weeks after the heart transplantation procedure.
21. The method according to claim 13 , wherein the surgical procedure includes a cardiac procedure selected from the group consisting of: a valve replacement procedure, and a valvoplasty procedure, and wherein identifying the subject comprises identifying the subject as one who is selected to undergo the selected cardiac procedure.
22. The method according to claim 13 , wherein the surgical procedure includes a percutaneous transluminal coronary angioplasty (PTCA) procedure, and wherein identifying the subject comprises identifying the subject as one who is selected to undergo the PTCA procedure.
23. The method according to claim 22 , wherein the potential adverse effect includes restenosis, and wherein reducing the likelihood comprises reducing the likelihood of the restenosis.
