Abstract: A catheter for diagnosing or treating the vessels found within a body or body space includes a center strut that is bonded, preferably thermally, along its longitudinal axis with the thermoplastic tubular member within which it is housed. The tubular member preferably has three layers: an inner layer, a braided layer and an outer layer. The composite catheter is made using a process in which two half-cylinder shaped mandrels are placed on each side of the center strut while the strut is heated in order to cause the thermal bonding. The bonded center strut provides in-plane deflection and improved transfer of torque to the tip of the catheter.

Abstract: A catheter for ablating tissue is provided. The catheter comprises an elongated generally-tubular catheter body having proximal and distal ends and at least one lumen extending therethrough. A non-retractable ablation assembly is attached to the distal end of the catheter body. The ablation assembly comprises proximal and distal non-conductive tubings, each having a lumen extending therethrough and a generally tubular electrode mounted between the proximal and distal non-conductive tubings. The tubular electrode is formed of a material having shape-memory and has at least one irrigation port through which fluid can pass from the inside to the outside of the electrode. The ablation assembly further comprises a non-conductive protective tubing extending generally parallel to and along the outside of the tubular electrode. The protective tubing has proximal and distal ends extending into the proximal and distal non-conductive tubings, respectively. The catheter further comprises at least one of an electrode lead wire and a temperature sensor wire, and preferably both, extending through the non-conductive protective tubing and catheter body, the electrode lead wire having a distal end mounted to a ring electrode mounted on the distal non-conductive tubing, and the temperature sensor wire having a distal end mounted on or under the distal non-conductive tubing. The catheter also comprises an infusion tube extending through the catheter body and having a distal end in fluid communication with the proximal end of the tubular electrode.

Abstract: A catheter adapted for mapping near a tubular region of a heart, has an elongated tubular catheter body having proximal and distal ends, an intermediate section distal of the catheter body, and a mapping assembly at the distal end of the intermediate section. The electrode-carrying mapping assembly has a generally circular main segment with a support member having shape-memory, and a generally linear proximal segment which has greater flexibility than either the intermediate section or the generally circular main segment. The generally circular main segment is adapted to releasably anchor itself in the tubular region and to map circumferentially around the tubular region and the generally linear segment is adapted to contact generally along its length heart wall tissue near an ostium of the tubular region. In another embodiment of the present invention, the mapping assembly extends from the distal end of the catheter body, where the generally linear proximal segment of the mapping assembly has greater flexibility than either the catheter body or the generally circular main segment.
