Problems solved by technology

The "count and cut" process employed during assembly to unwind and expose the correct wire along the body of the tube for welding to the electrode or thermocouple has become increasingly labor intensive during the production step. more time consuming
Also, if one electrode or one thermocouple connection fails during the final electrical inspection at the factory, if that failure cannot be reworked, then the entire catheter / probe will be considered scrap

Embodiment Construction

[0035] The present systems and methods can replace complex braided wire arrangements with flexible circuit arrangements in catheters and other medical devices. Medical devices built according to these methods are relatively simple to manufacture. Substantial reductions in production time and costs.

[0036] The methods described here can be applied in different medical procedures. For example, the method can be used to treat cardiac arrhythmias such as atrial fibrillation (AF) and ventricular tachycardia (VT). Methods of minimally invasive or intracardiac access may be performed using the probe / catheter described in this application. The electrodes used in the method can also be used to sense electrical activity from the heart, and the proximal connection of the probe / catheter can be attached to a programmed mapping system. Furthermore, these methods could be used in tissue desiccation and ablation procedures, for example, in oncology to selectively heat and destroy cance...

Abstract

Provided is a probe for use in medical procedures which includes a longitudinal member, a flexible sheath, and a flexible circuit. The longitudinal member includes at least one electrode and at least one thermocouple disposed thereon. The flexible sheath is coupled to and at least partially surrounding the longitudinal member. The flexible circuit is coupled to the sheath and also to the at least one electrode and the at least one thermocouple. The flexible circuit is configured to provide power to the at least one electrode and a return path to the at least one thermocouple.

Description

[0001] Cross References to Related Applications [0002] This application is a continuation-in-part of Serial No. 11 / 268,941 filed on November 8, 2005, filed on June 2, 2009. 11 / 268,941 claims priority to US Provisional Application Serial No. 60 / 625,859, filed November 8, 2004, and the contents of these applications are hereby incorporated by reference in their entirety. technical field [0003] This invention relates to catheters and other medical probes, and more particularly to the use of flexible circuits in such devices. Background technique [0004] Some catheters or surgical stylet tubes use a braided set of insulated copper wires that are interwoven in a complex cross-hatched design and run the length of the catheter or stylet. The braided tubing also serves as a conductor for conducting radiofrequency (RF) current to electrodes that ablate human tissue while sensing electrophysiological signals that travel along the same path to a monitoring system. [0005] An ...
