CATHETER WITH IMPROVED IRRIGATED TIP ELECTRODE HAVING TWO-PIECE CONSTRUCTION, AND METHOD OF MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a catheter.SOLUTION: A catheter has a two-piece tip electrode with a shell and a support structure that are secured to each other by multiple redundant mechanisms in order to reduce the risk of tip detachment during a procedure. The tip electrode includes at least two different welds attaching the shell to the support structure to provide a dual failure mode. One weld includes a seam weld, and another weld includes a penetration weld.
