System And Method For A Catheter Impedance Seeking Device

Patent Number: US 2010/0130854 Al

Date Filed: May 27, 2010

Country Filed In: USA

Product Application: MOSFET Catheter

A tissue-contact seeking method and apparatus is described that enhances catheter position detection and control systems in making and maintaining continuous tissue contact in a highly dynamic frame, such as under the rigors of cardiac motion. Tissue-seeking logical routines use a tissue contact sensing system to advance a catheter to relatively continuous tissue contact, or detect obstacles, in cooperation with the catheter position detection and control systems. Additional logical routines are capable of optimizing the contact direc­tion of the catheter tip by controlling the rotation angle and chamber position of the introducer.

Field of Use: The MOSFET Catheter was designed to be used in conjunction with the Catheter Guidance Control and Imaging (CGCI) system to provide physicians the ability to guide a catheter through a patient's body using a robotically controlled magnetic guidance system. The catheter greatly improved upon eliminating the issues regarding signal to noise ratio making the MOSFET Catheter much better at being able to generate high-fidelity mapping and imaging. Initial applications for the technology were for the field of Electrophysiology and specifically for the ablation of the heart to treat patients with AFib.
