摘要： An electrosurgical device includes a first electrode tip connected to a first shaft and spaced from a second electrode tip connected to a second shaft. The first electrode tip serves as a first pole, and the second electrode tip serves as a second pole, of a bipolar electrode configuration. A first fluid outlet opening is defined by a distal end of the first shaft and a portion of the first electrode tip. A second fluid outlet opening is defined by a distal end of the second shaft and a portion of the second electrode tip. At least one recess can be formed in an exterior surface of each of the first and the second electrode tips, providing a fluid flow channel for fluid to flow distally along the respective electrode tip.

摘要： An apparatus and method for the thermal treatment of tissue, e.g., prostatic tissue, with RF energy is disclosed. The apparatus includes a handle dimensioned to be grasped with a single hand of a surgeon, an elongated portion extending distally from the handle and defining a longitudinal axis, at least one electrode extending within the elongated portion and movable between a non-deployed position and a fully deployed position, and a trigger mechanism associated with the handle and having a trigger operatively connected to the one electrode. The trigger is movable to selectively and incrementally move the one electrode between the non-deployed position and the fully deployed position. A ratchet mechanism permits movement of the trigger in one direction corresponding to movement of the one electrode toward the fully deployed position while preventing movement of the trigger in a second direction. The elongated portion of the apparatus may be rotatable about the longitudinal axis to reposition the one electrode.

摘要： An fusion cage having a longitudinal element and two planar bendable expansion arms slideably captured in a track on opposing sides, the expansion arms expandable from a pre-implantation position adjacent to the longitudinal element to a deployed position bounding an area around the longitudinal element in which bone graft material may be packed and retained after implantation into the intervertebral space. The longitudinal element is eliminated in favor of front and back lateral tracks in which the opposing ends of the expansion arms are slideably received so as to allow expansion of the bounded areas in both a lateral and anterior-posterior direction by sliding within the channels. Expansion of the area within the bendable members may be accomplished by rotation of leaves to which the bendable members are rigidly and slideably affixed.

摘要： A heart valve implant according to one embodiment may include a shaft extending generally along a longitudinal axis of the heart valve implant having at least one anchor configured to be coupled to a first end of the shaft. A spacer may include a plurality of individual segments each including at least one passageway configured to be disposed about the shaft. The plurality of individual segments may define an outer surface of the spacer which is configured to interact with at least a portion of at least one cusp of a heart valve to at least partially restrict a flow of blood through the heart valve in a closed position. The plurality of individual segments may each having a length and at least one cross-section dimension no larger than an internal cross-section of a lumen of a delivery catheter.
