Kit for non-invasive electrophysiology procedures and method of its use

摘要

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.

主权项

1. An electrophysiology catheter for use with a steerable introducer sheath comprising:
a flexible catheter body having a proximal end and a distal end; at least two hollow elongate tip electrodes disposed at the distal end of the catheter body, the first and second hollow elongate tip electrodes each comprising a sidewall having at least one elongate gap to provide flexibility in the sidewall for bending movement of the at least two hollow elongate tip electrodes relative to a longitudinal axis of the catheter body, wherein each of the hollow elongate tip electrodes comprises an inner lumen that includes discrete lateral ports; and an electrically nonconductive segment separating the first and second hollow elongate tip electrodes, wherein the catheter body comprises an independent non-steerable structure.
