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.
