Abstract

An electrophysiology catheter for use with a steerable introducer sheath includes a flexible catheter body having a proximal end and a distal end and at least one hollow elongate tip electrode disposed at the distal end of the catheter body. The hollow elongate tip electrode includes a sidewall having at least one elongate gap that provides flexibility allowing the tip electrode to bend relative to a longitudinal axis of the catheter body. The catheter body is an independent, non-steerable structure, and can be moved via movement of the steerable introducer through which it is introduced into a patient.
