An electrosurgical probe for ablating tissue includes an elongated shaft having an axis and a distal end. An electrically insulating housing at the distal end of the shaft has a window, and an interior channel in the shaft extends through the housing to the window. The window faces laterally relative to the axis, and a moveable member with a blade-like electrode edge is disposed within the window. A motor drives the energized electrode edge axially in the window to ablate tissue.

A medical device for performing a hysterectomy is provided. The medical device has a tissue incision assembly that includes a first cup nested within a second cup. The tissue incision assembly also includes a spacer assembly between the first cup and the second cup in order to maintain a spacing between the first and second cups. The tissue incision assembly also has a cutting implement that has a portion extending between, and movable with respect to, the first and second cups. The cutting implement can provide a circular cut guided via the spacing between the first and second cups.

The present disclosure provides an electrode assembly wherein an electrically conductive material is configured to extend into an insulating moulding via an opening in a wall of said moulding to electrically contact an active tip placed into the insulating moulding and thereby retain the active electrode therein, such that the height and space required to anchor the active electrode within the moulding is greatly reduced while still providing the necessary retention strength and electrical connection. As such, the electrode assembly retains and connects the active tip with a conductive element that is mounted within the insulating moulding.

An electrosurgical electrode for coagulating and cutting tissue includes a main body fabricated from a conductive material, and a conductive blade extending inwardly from an inner surface of the main body. The blade has an edge configured to concentrate RF for cutting tissue.

An electrocautery unit for connecting to a handle of an electrocautery device, the unit comprises a body, a light unit and an electrode. The body has a body proximal end and a body distal end, and a body axis extending lengthwise along the center of the body. The body’s proximal end comprises a connecting element for connecting said body to a handle having a handle axis extending lengthwise along the center of the handle, so that said body axis is coaxial with said handle axis when said body is connected to said handle. The light unit may be constructed and arranged to emit a light having a central axis coaxial with said body axis. The electrode comprises a proximate end connected to the body distal end, and an electrode tip at a distal said. When the electrode is connected to the body, the electrode lays outside of the body axis and extends into said body axis such that the electrode tip is within said body axis, wherein said light and said electrode tip are coaxial to said body axis and said handle axis.

A suture method includes a first arrangement step of using a first treatment device including first/second grasping pieces to hook the first grasping piece to a first position of peripheral tissues of a lesion; a second arrangement step of hooking the second grasping piece to a second position of the peripheral tissues; a grasping step of grasping the first position and the second position while pressing the first position and the second position to the peripheral tissues; a retracting step of retracting the lesion site toward a proximal end side of the first treatment device while drawing the first position and the second position grasped by the first treatment device; and a suturing step of suturing a first suturing position at an external side of the first position and a second suturing position at an external side of the second position in the peripheral tissues.

Various embodiments are directed to battery unit for use with surgical instruments. The battery units may comprise a plurality of cells and include a translatable discharge drain. When attached to the surgical instrument, the discharge drain may electrically connect an anode of the battery unit to a cathode of the battery unit, for example, via a resistive element in order to drain the battery unit.

An electrosurgical device having first and second poles; blade electrode with a metal shim having two opposing faces and one or more facets, a nonconductive coating which covers at least the faces and a portion of the facets of the metal shim, while a distal portion of the one or more facets remains uncovered by the nonconductive coating; a lateral electrode comprised of a broad shim having one or more conductive faces and is placed parallel to the blade electrode so that at least one of the one or more conductive faces is exposed and a distal end of the blade electrode protrudes from the lateral electrode; the lateral electrode is fixed stationary relative to the blade electrode; the nonconductive coating insulates the blade electrode from the lateral electrode; and the first pole is connected to the blade electrode and the second pole is connected to the lateral electrode.

Prosthetic valves and associated methods and systems are disclosed, including a prosthetic valve with a support structure and a leaflet construct coupled to the support structure, and a tissue cutting element coupled to a portion of the prosthetic valve.
