An electrosurgical medical device may include a conductive tubular element disposed about an outer surface of an elongate tubular member at a distal portion of the tubular member. The conductive tubular member may be delivered to a treatment site of a gastrointestinal (GI) tract of a patient and electrically activated. While electrically activated, the conductive tubular element may create an opening in a wall of the GI tract and a pseudocyst. After the incision is made, the conductive tubular element may be withdrawn from the treatment site and a drainage device may be positioned in the incision for drainage of the pseudocyst.

A medical device comprising: (a) an interface including: (i) a first portion including: (1) a body portion connected to N a handle of a scalpel; and (2) a connection adapter; (ii) a second portion; wherein the connection adapter includes an interface portion that is a channel and the second portion includes an interface portion that is a tab that extends into the channel so that the first portion is connected to the second portion or wherein the second portion includes an interface portion that is a channel and the connection adapter includes an interface portion that is a tab that extends into the channel so that the first portion is connected to the second portion.

An electrosurgical wand is provided and includes a handle and an elongate shaft coupled to the handle and extending distally from the handle along an axis. An active electrode is disposed at a distal end of the electrosurgical wand. A return electrode abuts the elongate shaft and extends along and annularly about the axis. The return electrode has a top side adjacent the active electrode and an opposite bottom side and defines a notch. A support member is disposed in the notch between the electrodes and transitions curvilinearly from the notch to define a front surface extending laterally across and axially from the return electrode. The front surface tapers downwardly from the active electrode to define a first portion defining a first convex outer surface and also extends toward the bottom side of the return electrode to define a second portion defining a second convex outer surface.

An interchangeable tool assembly is disclosed. The interchangeable tool assembly includes a first jaw configured to support a staple cartridge during a first time period and a radio-frequency cartridge during a second time period. A second jaw is coupled to the first jaw. A surface of the second jaw defines a plurality of staple forming pockets configured to form staples driven from the staple cartridge. An electrically insulative material covers segments of the surface of the second jaw other than the staple forming pockets. The staple forming pockets define at least one return path for radio-frequency energy delivered by the radio-frequency cartridge.

A modular multi-electrode structure for use with an electrophysiology device includes a plurality of interconnected, non-conductive, tubular substrates. Each non-conductive, tubular substrate includes an outer surface and a conductor disposed on the outer surface, as well as at least one signal conductor extending along a length of the interconnected plurality of non-conductive tubular substrates. The conductor disposed on the outer surface of each non-conductive tubular substrate is in electrical communication with the at least one signal conductor. In some embodiments, the plurality of non-conductive tubular substrates includes a plurality of non-conductive polymeric substrates. In alternative embodiments, the plurality of non-conductive tubular substrates includes a plurality of non-conductive, unitary molded cylinders.

A device and method for compressing a renal artery prior to delivery of radiofrequency ablative energy to the renal nerves. The device includes a stent structure with a focal region that expands outwards to place the RF electrodes located on the stent structure in close proximity to the renal nerves. A covering is applied to the stent structure to prevent intimal hyperplasia.

The present invention relates to a treatment device and a method for controlling the same, and provides a treatment device comprising: an insertion unit formed to be insertable in tissue after penetrating through a surface of the tissue; a displacement measuring unit for measuring displacement of the surface of the tissue, caused by an insertion of the insertion unit; and a control unit for controlling an insertion motion of the insertion unit on the basis of the displacement measured by the displacement measuring unit. According to the present invention, the device allows medical treatment in a state in which the insertion unit has been inserted to reach a precise position of a target, so as to improve an effect of medical treatment.

A bipolar forceps includes a mechanical forceps including first and second shafts each having a jaw member extending from a distal end thereof and a handle disposed at a proximal end thereof for effecting movement of the jaw members relative to one another about a pivot. A disposable housing is configured to releasably couple to at least one of the shafts and an electrode assembly is associated with the disposable housing. The electrode assembly includes electrodes releasably coupleable to the jaw members. At least one of the electrodes includes a knife channel configured to receive a knife blade therethrough to cut tissue grasped between the jaw members. A switch is configured to initiate delivery of electrosurgical energy from the source of electrosurgical energy to the electrodes. An actuation mechanism is configured to selectively advance the knife blade through the knife channel to cut tissue.
