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
Description:
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.
