Abstract: PROBLEM TO BE SOLVED: To provide a method to make a high resolution three-dimensional map relating to electric activity on the inner face of the cardiac chamber. SOLUTION: This mapping system to map electric activity of the heart of a patient is equipped with an electrode set 19 separated from the cardiac wall 18 and electrode sets 24, 26 in contact with the cardiac wall 18. Voltage measurement values from those electrodes are used for generating a three-dimensional map and a two-dimensional map of electric activity of the heart. COPYRIGHT: (C)2004,JPO&NCIPI

Abstract: A mapping catheter assembly including a flexible lead body and a deformable lead body. A lumen is provided to accept a reference catheter which includes a distal tip electrode assembly. In use an array of electrode sites are deformed into a spherical shape after the assembly is placed in a heart chamber. The reference electrode assembly is advanced into contact with the heart wall to provide calibration information for the array.

Abstract: A method of representing the geometry of at least a portion of a human heart chamber includes positioning a catheter in a heart chamber. The position of the catheter in the heart chamber is determined. The catheter is re-positioned and the position is re-determined a plurality of times to determine the geometry of at least a portion of the heart chamber. A three-dimensional, anatomical representation of at least a portion of the heart chamber is then created.
