Abstract: A helical antenna structure for use in an electrosurgical instrument. The helical antenna structure is connectable to inner and outer conductors of a coaxial transmission line, and can act as both a radiating antenna or applicator structure, and also in a mode where an electric field is generated between its electrodes. In this way, the helical antenna structure may be used both for argon plasma coagulation, and deep tissue coagulation, as well as providing means for delivering a fluid, e.g. a therapeutic fluid such as adrenaline. This may be achieved through the use of helically arranged electrodes and a channel for gas to flow. This device is also used to deliver adrenaline and RF/microwave energy.

Abstract: 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.
