The present invention relates to systems for use for radio frequency ablation. The systems can include one or more of an ablation tool, power source for use with the ablation tool and a backstop for use in conjunction with the ablation tool during surgical procedures. Preferred ablation tools comprise a series of three or more blade-shaped electrodes disposed in a linear, curved, curvilinear or circular array. The backstops are useful for reducing direct physical and thermal heat transfer injuries to the patient or surgeon during procedures using radiofrequency (RF) ablation devices.

Sinusitis and other disorders of the ear, nose and throat are diagnosed and/or treated using minimally invasive approaches with flexible or rigid instruments. Various methods and devices are used for remodeling or changing the shape, size or configuration of a sinus ostium or duct or other anatomical structure in the ear, nose or throat; implanting a device, cells or tissues; removing matter from the ear, nose or throat; delivering diagnostic or therapeutic substances or performing other diagnostic or therapeutic procedures. Introducing devices (e.g., guide catheters, tubes, guidewires, elongate probes, other elongate members) may be used to facilitate insertion of working devices (e.g. catheters e.g. balloon catheters, guidewires, tissue cutting or remodeling devices, devices for implanting elements like stents, electrosurgical devices, energy emitting devices, devices for delivering diagnostic or therapeutic agents, substance delivery implants, scopes etc.) into the paranasal sinuses or other structures in the ear, nose or throat.

An electrosurgical lysing device and related methods. In some embodiments, the device may comprise a lysing tip comprising one or more beads. The bead(s) may comprise an at least substantially electrically non-conductive surface and may define, at least in part, both a distally-facing and a proximally-facing recess. At least one electrically conductive lysing member configured to deliver electrosurgical energy may be positioned adjacent to the at least one bead, the at least one lysing member defining at least one lysing segment extending within a recess at least partially defined by the at least one bead.

A method includes cutting a septal wall between a right atrium and left atrium of a heart of a patient to form a multi-cuspid valvular shunt, and ablating septal wall tissue of at least a portion of the multi-cuspid valvular shunt to cause the ablated portion of the multi-cuspid valvular shunt to be biostable.

Provided are Scissors for an endoscope that include a scissor mechanism part that includes a pair of scissor members connected to each other by a first spindle, and cuts a target site by opening and closing of the one scissor member and the other scissor member with the first spindle as a fulcrum; and an electrode part in which a monopolar electrode (electrode part) is formed on a distal end part of the one scissor member of the one scissor member and the other scissor member. An operator can quickly and extensively cut the target site by using the scissor mechanism part by the pair of scissor members, or can stop bleeding at the target site or cut the target site by using the electrode part.

Disclosed herein are methods and devices for the treatment of cellulite. The methods comprise cutting the septae connecting the dermis from the underlying fascia, reducing the appearance of dimples and applying a patch to the skin over the cut septae to hold in place or remodel the skin to allow it to heal in the desired shape and to minimize the recurrence of dimples.

A multifunctional surgical instrument (1) is provided. The multifunctional surgical instrument (1) comprises a proximal portion (13) and two legs (14), each leg comprising a distal end (11, 12), wherein a default position of the multifunctional surgical instrument is an open position, wherein the distal ends (11, 12) of the legs (14) do not meet in the open position, characterized in that each leg (14) comprises an aspiration half-channel (26, 27), the proximal portion (13) comprises an aspiration connection (29) and at least one of the distal ends (11, 12) comprises at least one aspiration orifice (28), wherein the two half-channels (26, 27) are configured to form an air-tight and water-tight continuous channel (25) connecting the at least one aspiration orifice (28) to the aspiration connection (29) when the multifunctional surgical instrument is in a fully closed position and are configured to open the aspiration channel (25) when the multifunctional surgical instrument is not in the fully closed position.

A colpotomy system includes an energy source and a uterine manipulator that is electrically coupled to the energy source. The uterine manipulator supports a colpotomy cup and extends to a conductive distal tip portion. The colpotomy cup includes a conductive surface. One or both of the conductive distal tip portion and the conductive surface of the colpotomy cup are configured to return monopolar energy to the energy source.

An electrosurgical device that has a head having a face. A handle connectable to an RF generator. The device has a plurality of teeth extending from the face. At least one of the plurality of teeth as a first electrical charge. A second of the plurality of teeth has a second electrical charge.
