A tissue resecting device includes an elongated shaft having a central axis, a distal end, and a proximal end. A ceramic or other housing is mounted at the distal end of the shaft and has a tissue-receiving window. A movable electrode is configured to be rotationally oscillated or otherwise moved across the window. In one instance, the rotatable moveable electrode may have a dogleg configuration with a free end constrained within an arcuate slot formed near the window. In another instance, the movable electrode may have a U-shaped configuration with a distal end coupled to a pivot in the housing which is aligned with a rotational drive member.

A jaw member of a surgical instrument includes a structural frame, an insulative spacer supported on the structural frame, an electrically conductive tissue contacting plate supported on the insulative spacer, and a lead wire. The spacer defines a pocket at an upper portion thereof and includes a channel extending from the pocket, through the spacer, to a bottom portion of the spacer. The channel defines a substantially U-shaped configuration having first and second radiused corners at the bottom portion of the spacer. The lead wire is attached to an underside of the plate at an attachment point within the pocket and extends distally from the attachment point into the channel, through the channel, over the first and second radiused corners, and proximally from the jaw member. The lead wire is adapted to connect to a source of energy to energize the plate for treating tissue.

A method is disclosed for the treatment of a thoracic region of a patient's body. Embodiments of the method comprise positioning an energy delivery portion of an electrosurgical device to face a segment of a thoracic vertebra at a distance from the segment; and cooling the energy delivery portion and delivering energy through the energy delivery portion.

A dual blade device and method useable for performing an ab interno procedure within a human eye to remove a strip of trabecular meshwork tissue.

To provide a treatment instrument that combines a capability to grip a target tissue and a capability to resect and ablate the target tissue without the need to interchange left and right devices or adjust a field of view of an endoscope, which can reduce burden on a surgeon.

A high frequency forceps includes a pair of forceps pieces configured to open and close on a pivot and equipped with incision blades adapted to pass a high-frequency current to a living tissue, in which the incision blades are formed, respectively, on opposite faces of the pair of forceps pieces, extending from a side of the pivot to a distal side; and the incision blades are spaced away from each other when the pair of forceps pieces is closed.

A tissue resection device comprises inner and outer coaxial sleeves. The outer sleeve has a cutting window formed therein, and the inner sleeve has a distal cutting end that can be reciprocated past the cutting window. The sleeves comprise electrodes to provide electrosurgical cutting, and an edge portion of the window includes a dielectric material.

The present disclosure relates to a bipolar catheter which enables a more precise surgical procedure by being configured to be able to evenly apply a high-frequency wave by an electrode tip being rotated inside a lesion area, and which can minimize damage to a surrounding tissue that can occur during an invasive surgery using a catheter, and which also enables a safer and more accurate surgical procedure compared to an existing surgical procedural method dependent on the medical technique of an operator, by electronically precisely controlling the position of the electrode tip within the lesion area.

An elongated medical needle includes an electrically-insulated elongated body having an outer surface extending between an electrically-insulated distal section and an electrically-insulated proximal section. An insulated electrically-conductive wire is aligned proximately along the outer surface between the electrically-insulated distal section and the electrically-insulated proximal section. An exposed electrically-conductive portion is mounted at the electrically-insulated distal section. The exposed electrically-conductive portion is electrically connected to the insulated electrically-conductive wire.

The disclosed technology includes a catheter comprising an elongated deflectable element extending along a longitudinal axis from a proximal end to a distal end, a position electrode attached to the elongated deflectable element proximate the distal end and configured for impedance-based position tracking, and a covering at least partially enclosing the position electrode. The covering can comprise a plurality of apertures such that a portion of a conductive surface of the position electrode is exposed through each aperture of the plurality of apertures.

A transseptal needle or punch. The transseptal punch includes a stylet with a tube with a side window and a cutting wire disposed within the tube, with a sharp cutting segment disposed proximate the window. The sharp cutting segment can be expanded radially outwardly from the window by translation of the cutting wire proximal end within the tube.
