Apparatus and systems include an electrosurgical instrument with a unique jaw configuration and gripping surfaces that allow tangential gripping and ablation of tissue in a minimally invasive procedure. The electrosurgical instrument can include a shaft and hinge coupling the shaft to first and second jaws. The first jaw can be an anchor for the second jaw. The jaws can have respective first portions and second portions offset at an angle from the first portions. Each jaw can also include electrodes on their inner surfaces facing the other jaw. Each jaw can also include textured gripping surfaces. The gripping surfaces can be included on at least a portion of the base of each jaw, as well as on at least a portion of the inner surfaces of the jaws.

An irrigating bipolar forceps may include a first forceps arm, a conductor tip of the first forceps arm, a second forceps arm, a conductor tip of the second forceps arm, an input conductor isolation mechanism, and irrigation tubing. A proximal end of the first forceps arm may be disposed within the input conductor isolation mechanism and a proximal end of the second forceps arm may be disposed within the input conductor isolation mechanism. An application of a force to a lateral portion of the forceps arms may be configured to close the forceps arms. A reduction of a force applied to a lateral portion of the forceps arms may be configured to open the forceps arms. The irrigation tubing may transport a fluid from an irrigation supply system to a surgical site.

Novel and versatile apparatuses for delivering one or more of thermal ablation and irreversible electroporation therapies to target tissue. In some examples, a device includes at its distal end a plurality of electrodes that can be advanced or retracted to pierce patient tissue, with a variable position and size shaft electrode provided near the distal end of the device to allow manipulation of therapy fields to achieve various tissue destruction field shapes. A number of method of use examples are described as well.

A method of manufacturing a thermal cutting element for a surgical instrument includes manufacturing a substrate, coating at least a portion of the substrate via Plasma Electrolytic Oxidation (PEO), and disposing a heating element on at least a portion of the PEO-coated substrate. The method may further include attaching the thermal cutting element to a jaw member of a surgical instrument.

The present invention relates to a conductive electrode which is used for an electrosurgical handpiece and, more particularly, to a conductive electrode for an electrosurgical handpiece, wherein the conductive electrode is split into two pieces, and thus not only a general surgery can be performed as in the conventional electrosurgical handpiece, but also a precise surgery can be performed by even an unskilled surgeon, and the fatigue of an operating surgeon can be reduced.

An exemplary tissue detection and location identification apparatus can include, for example, a first electrically conductive layer at least partially (e.g., circumferentially) surrounding a lumen, an insulating layer at least partially (e.g., circumferentially) surrounding the first electrically conductive layer, and a second electrically conductive layer circumferentially surrounding the insulating layer, where the insulating layer can electrically isolate the first electrically conductive layer from the second electrically conductive layer. A further insulating layer can be included which can at least partially surrounding the second electrically conductive layer. The first electrically conductive layer, the insulating layer, and the second electrically conductive layer can form a structure which has a first side and a second side disposed opposite to the first side with respect to the lumen, where the first side can be longer than the second side thereby forming a sharp pointed end via the first side at a distal-most portion. The exemplary configuration can be used for (a) determination/detection of a tissue type using impendence of the electrically conductive layers, and/or (ii) determination of a location of at least one portion of the insertion device/apparatus. Based on such determination, it is possible to effectuate ablation or heating of tissue by applying RF energy across the electrically conductive layers.

The instant disclosure relates to electrophysiology catheters for tissue ablation within a cardiac muscle, for example. In particular, the instant disclosure relates to an electrophysiology ablation balloon catheter with a combination of coated and uncoated surfaces for focusing ablation energy at a desired portion of tissue.

A surgical device and associated methods are disclosed. In one example, the surgical device includes tungsten disulfide covering all or a portion of a component.

A method and apparatus are disclosed for an RF guidewire for applying RF energy to create a channel through a region of tissue within a patient's body. The RF guidewire is configured to have a hydrophilic coating disposed thereon to reduce friction to facilitate traversal through vasculature while maintaining its mechanical, electrical and thermal properties. The RF guidewire includes an electrode tip at a distal end of the guidewire for delivering the energy and an electrically insulative thermal shield between the electrode tip and electrical insulation for thermally protecting the electrical insulation from heat produced by delivering the energy. Some embodiments include electrical insulation inside of the electrically insulative thermal shield.

A light based skin treatment device comprises a laser light source for providing a pulsed incident light beam for treating skin by laser induced optical breakdown of hair or skin tissue. In one arrangement, a focusing system has a pre-focusing lens for increasing the convergence of the an incident light beam and a skin contact lens having convex light input and light exit surfaces. The focal spot position is controlled by adjusting a spacing between the pre-focusing lens and the skin contact lens. In another arrangement, there is an adjustable lens system before an adjustable focusing system for providing compensation for aberration in the focusing system.
