Abstract: A medical device includes a handle, including a movable body. The medical device also includes a shaft extending from the handle, and an electrode at a distal end of the shaft. Movement of the movable portion of the handle controls a position of the electrode relative to the distal end of the shaft. At least a portion of the shaft includes a braiding.

Abstract: A tissue closure device includes a suture extending longitudinally from a proximal end to a distal end; a distal barb element including at least one distal arm extending from a first end connected to the distal end of the suture to a second end extending toward the proximal end of the suture, the distal barb movable between an engaging configuration, in which the distal arm extends away from the suture; to a non-engaging configuration in which the distal arm is moved toward the suture; and a proximal barb element slidably mounted over the suture and including a proximal arm extending from a first end connected to a base portion mounted over the suture to a second extending toward the distal end of the suture, the proximal barb element movable between an engaging configuration and a non-engaging configuration.
