Classification: CPC A  H | IPC A  H

Claim 0:
1. A method of treating tissue, the method comprising:
applying a plurality of electrical pulses having an amplitude of greater than 0.1 kV to a proximal end of a catheter inserted into a body of a subject through a first conductive layer formed from a first plurality of braided or woven filaments extending at least partially down a length of the catheter and through a second conductive layer extending coaxial to the first conductive layer; and
delivering the plurality of electrical pulses to the body of the subject from a first electrode at a distal end region of the catheter in electrical communication with the first conductive layer and a second electrode at the distal end region of the catheter in electrical communication with the second conductive layer,
wherein the first and second conductive layers are configured to prevent electromagnetic interference (EMI) arising from the first and second conductive layers at high voltages and rapid pulse rates.
