Map and ablate closed-loop cooled ablation catheter

摘要

A system for performing mapping and ablation functions includes a catheter sized and shaped for vascular access. The catheter includes an elongate body extending between a proximal end and a distal end. A tip section positioned at the distal end of the catheter body and includes a proximal portion and a distal portion. One or more electrode structures are formed on an exterior surface of the tip section. The one or more electrode structures each includes a mapping electrode at the distal portion of the tip section and a contact pad electrically coupled to the mapping electrode.

1. A system comprising:
a catheter sized and shaped for vascular access and including an elongate body extending between a proximal end and a distal end; a tip section including an ablation electrode configured to deliver radio frequency (RF) energy for an RF ablation procedure and positioned at the distal end of the body, the tip section including a proximal portion and a distal portion; and one or more electrode structures on an exterior surface of the ablation electrode, the one or more electrode structures each including a mapping electrode at the distal portion of the tip section and a contact pad electrically coupled to the mapping electrode.
