The invention provides a cartridge assembly to couple a tissue treatment device with an electrosurgical unit, with the cartridge assembly operable with a power delivery apparatus and a fluid delivery apparatus of the electrosurgical unit. The invention also provides an electrosurgical unit comprising a power delivery apparatus and a fluid delivery apparatus operable with the cartridge assembly and a system thereof.

Surgical device

A cartridge assembly to couple an electrosurgical device to treat tissue with an electro surgical unit includes a cartridge member to operate with a power delivery apparatus of the electro surgical unit and a fluid delivery apparatus of the electro surgical unit. An electrosurgical unit includes a power delivery apparatus and a fluid delivery apparatus arranged to operate with a cartridge member to be located in a cartridge receptacle of the electrosurgical unit. An electrosurgical device includes a first electrode spaced alongside the second electrode, with each electrode having a blade shaped member. Each blade shaped member has opposing sides bounded by edges, with the edges having a medial edge and a lateral edge. At least one fluid outlet is adjacent each blade shaped member, and each fluid outlet is in fluid communication with a fluid passage. The device can be operated as either a bipolar device or a monopolar device and includes a switch to inhibit capacitive coupling to one of the electrodes when the other electrode is used in monopolar fashion.

Electrosurgical devices, electrosurgical unit and methods of use thereof

An electrosurgical device includes a first electrode spaced alongside a second electrode. The device can be operated as either a bipolar device or a monopolar device and includes a switch to inhibit capacitive coupling to one of the electrodes when the other electrode is used in monopolar fashion.

Cartridge assembly for electrosurgical devices, electrosurgical unit and methods of use thereof

A method of producing an electrosurgical device is disclosed. Opposing longitudinal clamshells are formed, and each clamshell includes a face having a generally planar major portion. Longitudinal grooves are formed in a clamshell, and an electrical conductor in a disposed in a groove. The faces are aligned to form an electrical passage including the electrical conductor in the groove and a spaced-apart fluid passage with another groove. The clamshells are welded together to form a shaft member such that the electrical passage and the fluid passage are fluid tight along a major longitudinal portion of the shaft. Electrodes are attached to the distal end of the shaft and are in electrical communication with the electrical conductor.

The invention provides a bipolar electrosurgical device to treat tissue in a presence of radio frequency energy and a fluid provided from the device. In one embodiment, the device comprises a first electrode and a second electrode at the end of a malleable shaft assembly to be hand shapeable by a user of the device, and at least one fluid outlet. The malleable shaft assembly comprises a first shaft and a second shaft, a length of the first shaft and a length of the second shaft in an outer member comprising a polymer, and at least a portion of the first shaft and at least a portion of the second shaft being malleable.
