摘要： An ablation system includes an ablation source, an ablation probe having an ablation element coupled to a power terminal of the generator, and a ground probe coupled to a return terminal of the generator, the ground probe configured to be inserted within a body during use. One of the ablation probe and the ground probe is configured for being intravascularly introduced to an interior of an organ, and another of the ablation probe and the ground probe is configured for being extravascularly placed in contact with an exterior of the organ. A method of ablating tissue having a thickness includes placing one of an ablative element and a ground element in a first location adjacent the tissue, placing another of the ablative element and the ground element in a second location adjacent the tissue, and delivering ablation energy through the thickness of the tissue between the ablative and ground elements.

摘要： A medical probe includes an elongate member having a proximal end and a distal end, an ablative element mounted to the distal end of the elongate member, and a cage assembly mounted to the distal end of the elongate member, the cage assembly at least partially covers the ablative element. A method of treating tissue in a body includes inserting an ablative element in the body, placing the ablative element adjacent the tissue, and maintaining a distance between the ablative element and the tissue using a protective catheter element that circumscribes at least a portion of the ablative element.

摘要： An electrode assembly adapted to transmit electrical energy for ablating body tissue includes an expandable and collapsible non-compliant body made of a durable material and defining an interior adapted to receive a medium containing ions. The body includes a porous region, an electrode adapted to transmit electrical energy located in the interior of the body, a microporous membrane located on the porous region of the non-compliant body, and the microporous membrane is sized to pass ions contained in the medium without substantial medium perfusion therethrough, to thereby enable ionic transport of electrical energy from the ion-containing medium to the exterior of the electrode assembly to ablate body tissue.

摘要： Tubing made of two or more polymers circumferentially arranged around the perimeter of the tubing in a single layer may be useful as medical tubing. Specifically, such tubing may be useful in catheters, sheaths, sheath introducers, implant delivery systems, and other medical devices having elongated tubular components. Selection of the two or more polymers based on the durometer and melting temperature permits optimization of axial strength and flexibility for particular applications. Such tubing may be extruded as a single layer tubing or a multi-layer tubing where the additional layers may be single material layers or more multi-polymer layers.
