摘要: A medical device for delivering RF energy to a target tissue region includes an elongate delivery cannula having a lumen in communication with a distal opening. A deployment member is positioned and longitudinally movable in the lumen. An array of electrode elements are secured to a distal end of the deployment member, the deployment member being movable from a delivery position, in which the electrode elements are positioned within the lumen, to a deployed position, in which the electrode elements extend distally out of the cannula distal opening. A sealing member formed from a bio-compatible material sufficiently rigid to penetrate solid body tissue partially extends from, and substantially seals, the distal cannula opening when the deployment member is in the delivery position.

摘要: Described is a method and a device for inserting a helical member into a living body. The device may include a handle having an actuator lever rotatably coupled thereto. The device may also include a helical member which has a tissue piercing distal tip. The helical member is coupled to the handle via a linkage operating so that, as the actuator lever is rotated in a first direction relative to the handle, the helical member is rotated and moved distally to screw into tissue along a substantially helical path.

摘要: An apparatus for delivering electrical energy includes a cannula and one or more needles extendable from and retractable into a lumen of the cannula. A distal portion of each needle is extendable from the lumen and terminates in a tissue-piercing distal tip. Each distal portion is formed from an electrically conductive and porous material, thereby providing a porous electrode through which electrolytic fluid may flow for delivering electrical energy to tissue surrounding the distal portion. The cannula is introduced into a tissue structure of a patient, the one or more needles are advanced from the cannula, saline is introduced from the porous material to surrounding tissue, and electrical energy from an RF generator is delivered to ablate tissue within the tissue structure.
