    摘要: A catheter suitable for use in applying ablation energy to body tissue or detecting electrical signals conducted within the body tissue is disclosed. The catheter has a deflectable distal tip section. At least one electrode is adapted to be disposed against body tissue for delivery of ablation energy thereto or for conduction of body tissue electrical signals. An actuation mechanism comprising first and second pull wires is adapted to curve a proximal segment in a first direction and to independently bend an intermediate segment in a second direction.

    摘要: Systems and methods for securing a screen-type active electrode to the distal tip of an electrosurgical device used for selectively applying electrical energy to a target location within or on a patient's body. A securing electrode is disposed through the screen electrode and mechanically joined to an insulative support body while also creating an electrical connection and mechanical engagement with the screen electrode. The electrosurgical device and related methods are provided for resecting, cutting, partially ablating, aspirating or otherwise removing tissue from a target site, and ablating the tissue in situ. The present methods and systems are particularly useful for removing tissue within joints, e.g., synovial tissue, meniscus, articular cartilage and the like.

    摘要: A tool for slitting an elongate sheath from about an elongate member that is disposed within a longitudinally extending lumen of the sheath includes a longitudinally extending tail portion projecting rearward of a slitting edge and a nose portion of the tool; a lower surface of the nose portion is disposed beneath the slitting edge for engaging a portion of the elongate member. The tail portion of the tool, approximately aligned with the sheath lumen when the lower surface, engages the elongate member and a leading edge of the nose portion is within the sheath lumen, is sized to fit within the sheath lumen after the sheath is slit by the slitting edge. A passageway between the nose portion and the tail portion allows a proximal segment of the elongate member to bend away from the tail portion when the elongate member is engaged by the nose portion.
