A method is disclosed. The method includes delivering staples from a surgical staple cartridge of a surgical instrument to a first tissue during a first procedure; removing the surgical staple cartridge from the surgical instrument; and delivering radio-frequency energy from a radio-frequency cartridge of the surgical instrument to a second tissue during a second procedure.

A clip-over disposable assembly includes a switch assembly and a disposable body. The disposable body includes a first disposable member, a second disposable member including first and second wall portions, and a third disposable member. The first wall portion defines a first aperture therethrough and a first cavity configured to receive therein a first portion of the switch assembly. The third disposable member includes a third wall portion, wherein a body of the second disposable member and the third wall portion define an opening configured to allow a shaft of a hemostat-style surgical instrument to pass therethrough. The second wall portion and the third wall portion cooperatively define a chamber in communication with the opening and configured to receive therein at least a portion of the shaft of the hemostat-style surgical instrument, wherein the at least a portion of the shaft is received in the chamber from an off-axis position.

An endoscopic device for biportal endoscopic spinal surgery is proposed. The device includes: a guide tube as a hollow tubular member extending in a longitudinal direction and having a front end thereof reaching a target site in a patient's body when being used, the guide tube accommodating a probe of an endoscope inserted therein; a saline solution guide part mounted on a rear end of the guide tube and guiding a saline solution injected from an outside to an inside of the guide tube; and an adapter part positioned at the rear end of the guide tube and guiding the probe of the endoscope to use to the guide tube.

A portable electrosurgical device (ESD) has a housing, a probe connected to the housing and a heating element connected to the probe for destroying human tissue. The heating element is detachable from the probe and/or the probe with heating element can be detachable from the housing. The user can set a drive signal's electrical characteristics, such as operating frequency, duty cycle, peak voltage and the like for a customized drive signal formed in the ESD based on the heating element used. Memory storage allows for storage of inputted data from a keyboard, downloaded reference documents and information off the Internet from an Ethernet connector that can be displayed for reference on a screen of the ESD. Another even more compact ESD is an integral one-piece portable device having a type of pistol hand-held grip, dis-connectable probe, and a rechargeable, removable battery in the handle provides approximately 30, one-minute treatments on a single battery charge.

An electrode assembly for an electrosurgical instrument includes a housing having an active electrical connector and a return electrical connector configured to operably engage a distal end of an electrosurgical instrument shaft, the housing encapsulating an elongated return electrode and a pair of insulative tubes configured to house a wire-like active electrode. The elongated return electrode includes a clevis at a distal end thereof and operably engages to the return electrical connector at a proximal end thereof. The wire-like active electrode operably engages at one end to the active electrical connector. A donut-like insulator is operably engaged to the clevis of the elongated return electrode and is configured to support the wire-like active electrode therearound. A tensioning mechanism is configured to operably engage an opposite end of the wire-like electrode and tension the wire-like active electrode about the donut-like insulator during assembly.

An ophthalmic surgical apparatus includes: a support provided with an electrical path, and a probe including a conductive material, the probe including a first section coupled to the support and a second section formed integrally with and connected to the first section, the entire surface of the second section being exposed to the outside of the support.

An electrosurgical device kit includes an elongate first member, an elongate second member disposed adjacent to the first member, the second member being at least movably coupled to the first member, a first electrode head removably attachable to the first member, a second electrode head removably attachable to the first member, and a third electrode head coupled to the second member. The first, second, and third electrode heads are configured to apply a current to a tissue, the first and second electrode heads being non-identical.

The invention provides for a device (100) for use in electrical nerve modulation in a subject, characterized in that it comprises a rotational and linear actuator (110); a tubular element (101) having a proximal end connected to the actuator (110) and a distal end; a flexible shaft (102) coaxially disposed within the tubular element (101), comprising a proximal end operably connected to the actuator (110) and a distal end, and adapted to be slid along the tubular element (101); a conformable support (103) comprising a proximal end operably connected to the tubular element's (101) distal end, and a distal end operably connected to the flexible shaft's (102) distal end, having a portion of its length helically wrapped about a distal portion of the flexible shaft (102) so to define a pitch (500) and a radius (400); and a plurality of electrodes (104) operably disposed along the helically configured portion of the conformable support (103), and electrically connectable to a generator (200), adapted to contact the endoluminal surface of a blood vessel of the subject and deliver electrical energy; wherein the pitch (500), radius (400) or both of the helically configured portion of the conformable support (103) can be modified via actuator's (110) driven extension, retraction and/or rotation of the flexible shaft (102).

Apparatus, systems, and methods are provided for monitoring AF episodes, delivering ATP pulses, and/or achieving electrical isolation of the left atrial appendage (LAA) of a patient's heart and/or preventing thrombus formation after electrical isolation. For example, devices are provided that may implanted from within the left atrium, e.g., to isolate the LAA, prevent thrombus formation within the LAA, facilitate endothelialization, and/or deliver pacing.
