ROBOTIC ABLATION CATHETER

摘要

Assemblies, systems, and methods related to remotely-steerable ablation procedures are described. A necked-down ablation catheter may be coupled within a working lumen of a robotically-steerable sheath configured to be driveably coupled to an electromechanical instrument driver. The ablation catheter may be an irrigated ablation catheter having an irrigation fluid reservoir at its distal tip. The outer diameter of the distal portion of the ablation catheter is generally larger than that of the more proximal aspects due, in part, to the fact that the proximal aspects are designed to fit through a relatively low-profile steerable sheath.

主权项

1. A method of assembling an integrated robotic ablation catheter comprising a robotic sheath and a necked down ablation catheter, the method comprising:
inserting a proximal end of a necked-down ablation catheter into a distal end of a working lumen of a robotic sheath, wherein the necked-down ablation catheter comprises a distal ablation tip having an outer diameter that is larger than a diameter of the working lumen; advancing the proximal end of the necked-down ablation catheter through the working lumen; and attaching a proximal end coupler to the necked-down ablation catheter.
