摘要： A catheter configured to guide and support a balloon catheter for use in and around a pulmonary vein and its ostium, has an elongated shaft and a distal assembly, the elongated shaft including a proximal portion with a first flexibility and a distal portion including a second flexibility greater than the first flexibility, the distal assembly including an elbow portion and a generally circular portion generally transverse to the longitudinal axis, the generally circular portion including a third flexibility greater than the second flexibility. Single axis location sensors and sensing ring electrodes are carried on the generally circular portion.

摘要： Medical apparatus includes a flexible insertion shaft, which is adapted for insertion into a body of a patient. A resilient end section is fixed to the distal end of the insertion shaft and is formed so as to assume, when unconstrained, an arcuate shape. One or more electrodes are disposed at respective locations along the end section. A first lumen runs from the insertion shaft through the end section so as to convey an irrigation fluid to exit the end section through perforations of the electrodes. A second lumen runs through the insertion shaft to a distal opening and is configured to permit a guide wire to pass through the second lumen from the proximal end of the insertion shaft to exit distally through the distal opening, while conveying the irrigation fluid from the proximal end through the distal opening together with the guide wire.

摘要： A catheter is provided with improved position and/or location sensing with the use of single axis sensors that are mounted directly along a length or portion of the catheter whose position/location is of interest. The magnetic based, single axis sensors are provided on a single axis sensor (SAS) assembly, which can be linear or nonlinear as needed. A catheter of the present invention thus includes a catheter body and a distal member of a particular 2D or 3D configuration that is provided by a support member on which at least one, if not at least three single axis sensors, are mounted serially along a length of the support member. In one embodiment, the magnetic-based sensor assembly including at least one coil member that is wrapped on the support member, wherein the coil member is connected via a joint region to a respective cable member adapted to transmit a signal providing location information from the coil member to a mapping and localization system. The joint region advantageously provides strain relief adaptations to the at least one coil member and the respective cable member from detaching.
