摘要： The ablation catheter is comprised of a guiding catheter and an inner catheter. The guiding catheter is comprised of a shaft section which is attached to an articulating section at its distal end and a first handle at its proximal end. The inner catheter is comprised of an elongated central shaft, an electrode assembly attached to the distal end of the central shaft, and a second handle attached to the proximal end of the central shaft. The electrode assembly is comprised of a flexible plastic catheter tube having an outer surface, a porous tip electrode, and at least one linear electrode carried on the outer surface of the catheter tube. The electrode assembly is articulated to better align the electrode assembly to the generally arcuate shape of the inner chambers of the heart.

摘要： A method of and an apparatus for performing electrophysiological mapping of myocardial tissue. An electrode at a distal portion of a sensing catheter electrically contacts the tissue permitting the catheter to conduct a sensed signal to analysis and display equipment. The electrode is formed of a biocompatible metal. This basic structure is coated with a material with micro texturizes the electrode surface to increase the effective surface area without significantly increasing the electrode footprint.
