Abstract
A catheter shaft includes an elongate body extending from a proximal end to a distal end and including a proximal portion and a deflectable distal portion. The distal portion is selectively deflectable in at least one direction by actuation of a shaft actuator assembly. The elongate body defines at least one lumen extending from the proximal end to the distal end. The catheter shaft also includes a loop actuation wire extending through the at least one lumen and being operable to selectively adjust a diameter of an electrode loop assembly coupled at the distal end of the elongate body. The catheter shaft further includes a first coil wound around the loop actuation wire along the proximal portion of the elongate body and a second coil wound around the loop actuation wire along the distal portion of the elongate body. The second coil has a more flexible construction than the first coil.
