Method And Apparatus For Creating A High Resolution Map Of The Electrical And Mechanical Properties Of The Heart
Patent Number: WO 2009/134605 A2
Date Filed: November 5, 2009
Country Filed In: WIPO
Product Application: CGCI
Description:
A system method that tracks one or more points on the surface of a cardiac tissue throughout a cardiac cycle and collects various types of data points which are then subsequently used to generate a corresponding model of the tissue and display the model as a 3D color-coded image is described. In one embodiment, the system determines the position and orientation of a distal tip of a catheter, manipulates the catheter tip so as to maintain constant contact between the tip and a region of cardiac tissue using the impedance method, acquires positional and electrical data of the tip-tissue configuration through an entire heartbeat cycle, repeats the measurements as many times as needed in different tissue regions, and forms a 3D color-coded map displaying various mechanical and electrical properties of the heart using the acquired data.
Field of Use: The Catheter Guidance Control and Imaging (CGCI) system was created to provide physicians the ability to guide a catheter through a patient's body using a robotically-controlled magnetic guidance system. Such a system provides the physician unprecedented accuracy in being able to navigate within the dynamic environment of the patient, create a detailed 3-D mapping, and perform a variety of catheter-based operations with precision control and an ability to return to target at the push of a button. Initial applications for the technology were for the field of Electrophysiology and specifically for the ablation of the heart to treat patients with AFib.
