Patent number: 11786302Abstract: A device and method is disclosed for creating a lesion in adventitia tissue of a renal artery and/or a region of tissue surrounding the adventitia tissue while protecting intima and media tissue of the renal artery from injury. A catheter carrying a microwave antenna is positioned within the renal artery. Cooling fluid is circulated around the microwave antenna in thermal contact with the intima of the renal artery. Power is supplied to the microwave antenna to cause microwave energy to be emitted omnidirectionally from the microwave antenna. The power supplied to the microwave antenna and the cooling fluid circulated around the microwave antenna are controlled to cause the adventitia tissue and/or the region of tissue surrounding the adventitia tissue to be heated to a temperature sufficient to cause thermal damage while the intima and media tissue are maintained at a temperature where thermal damage does not occur.Type: GrantFiled: October 5, 2018Date of Patent: October 17, 2023Assignee: Denervx LLCInventor: Eric N.
