摘要： A catheter having a proximal portion and a distal portion terminating in a distal tip, is provided with a spring assembly contained within its distal tip portion for providing a bias against side to side deflection of said distal tip. The assembly preferably includes a central wire having a first diameter, which central wire extends from the proximal portion of the catheter to the distal portion, and a plurality of wires secured to the central wire adjacent the distal end thereof. Each of the wires is stranded together, preferably twisted helically, around the central wire and preferably has a second diameter substantially smaller than the first diameter. Alternatively, the stranded wires can be attached along and parallel to the larger diameter wire, and the latter wire is of a substantially greater length than the stranded wires.

摘要： A catheter has an electrode tip assembly that is bendable at the selection of the user in two different directions. The electrode tip assembly assumes different asymmetric predetermined curve configurations when bent in the two directions and is manipulated by means of steering wires adjustably connected tangentially to the lateral edges of a rotatable cam located in the catheter handle.

摘要： Ablation systems comprise a support body, an energy transmitting element supported by the support body and an insulating member covering a portion of the support body and energy transmitting member. Ablation energy is transmitted from an uncovered, exposed portion of the energy transmitting element. The insulating member may be a distal portion of an introducer sheath. An open segment may be provided in the distal portion to expose a portion of the energy transmitting element. When used in cardiac ablation therapy, for example, the insulating member decreases the amount of ablation energy dissipated in the blood circulating through the heart and thermally insulates the energy transmitting member and the tissue at the ablation site, enabling better control of the ablation process. An inflatable balloon or an expandable web may be provided coupled to the distal portion of the sheath behind the open segment to provide further insulation of the energy transmitting element and of the tissue around the ablation site. In another embodiment, ablation catheters incorporate an insulating member such as the inflatable balloon, expandable web or a cover. Methods of ablating tissue are also disclosed.

摘要： Systems and methods for reducing the number of temperature measurement wires in multiple temperature sensor ablation systems are described. In a preferred embodiment, temperature sensors capable of measuring the temperature of body tissue and transmitting the temperature data digitally are incorporated in a catheter or probe ablation system that also includes electrodes in operative contact with the sensors. The sensors are connected in parallel to a common electrical bus, thereby allowing the system to operate using a reduced number of electrical paths as compared to conventional ablation systems. The present invention is also directed to ablation systems that incorporate analog sensors rather than digital sensors. In this embodiment, the system utilizes digital switching, filtering circuits, or oscillators to reduce the number of wires required to operate the sensors.
