Certain aspects relate to systems, devices and techniques for vessel sealing and cutting. In particular, an instrument is provided that is capable of performing multiple functions, including sealing and cutting. The instrument can be robotically controlled, and can include a shaft, a multi-DOF wrist, and an end effector. The end effector is capable of generating and delivering heat via different energy modalities to perform the various functions at different temperatures.

A probe for ablating tissue comprises an electrosurgical working end configured to provide a first plasma about a first surface location and a second plasma about a second surface location, the first plasma having first ablation parameters and the second plasma having second ablation parameters. The probe has a working end with a thickness below 3 mm and produces a low temperature plasma.

A device for applying radiofrequency energy for sphincter treatment comprising a flexible outer tube, an expandable basket having a plurality of arms movable from a collapsed position to an expanded position, and a plurality of electrodes movable with respect to the arms from a retracted position to an extended position. An advancer is slidably disposed within the outer tube to move the plurality of electrodes to the extended position. An actuator moves the advancer from a first position to a second position to advance the plurality of electrodes. An aspiration tube extends within the outer tube. An assembly includes an aspiration disabler having a first position to enable aspiration from a distal portion of the aspiration tube to a proximal portion and a second position to disable aspiration.

Embodiments include devices and methods configured to fractionally resect skin and/or fat. Fractional resection is applied as a stand-alone procedure in anatomical areas that are off-limits to conventional plastic surgery due to the poor tradeoff between the visibility of the incisional scar and amount of enhancement obtained. Fractional resection is also applied as an adjunct to established plastic surgery procedures such as liposuction, and is employed to significantly reduce the length of incisions required for a particular application. The shortening of incisions has application in both the aesthetic and reconstructive realms of plastic surgery.

A method and system for tattoo removal from a subject by exposing tattoo ink particles trapped within the dermis to a cold plasma is described herein. The tattoo removal method and system can be used to remove the tattoo from the skin of the subject being treated. In addition, the method and system described allows for the extraction of the tattoo ink particles, which may have toxic properties, from the subject's body.

The present disclosure relates generally to the field of cryoablation. In particular, the present disclosure relates to cryoablation systems (e.g., cryospray systems, cryogenic ablation, cryosurgery systems etc.) that prevent or significantly inhibit cryospray gases from accumulating and progression distally beyond a specific region within a body lumen.

A handpiece for a surgical instrument, having a lumen for the provision of suction or fluids to the surgical instrument, the lumen being formed from at least two concentrically arranged tubes, one of the tubes being formed from metal, and the other of the tubes being formed from an electrically insulating material, the arrangement being such as to prevent electrical charge carried by any fluid within the lumen from leaking to an external surface of the lumen. In one example the at least two concentrically arranged tubes define a tube connector having a distal end and a proximal end, wherein the proximal end is located within a receiving formation in the handpiece and the distal end protrudes outwardly from the handpiece.

A tissue cutting probe includes an outer sleeve assembly, an inner sleeve assembly, a burr and an electrode. Each of the inner and outer sleeves has a proximal end, a distal end, and central passage extending therebetween. The inner sleeve assembly is coaxially and rotatably received in the central passage of the outer sleeve assembly, and the burr has a plurality of metal cutting edges carried on a first side of the distal end of the inner sleeve assembly. The electrode is carried a second side of the distal end of the inner sleeve assembly.

A prostate therapy system is provided that may include any of a number of features. One feature of the prostate therapy system is that it can access a prostate lobe transurethrally. Another feature of the prostate therapy system is that it can deliver condensable vapor into the prostate to ablate the prostate tissue. Methods associated with use of the prostate therapy system are also covered.

An ultrapolar telescopic electrosurgery pencil that can be used in both monopolar and bipolar modes for cutting and coagulation. The ultrapolar telescopic electrosurgery pencil can operate at very low power levels (such as 15-20 Watts or less) to both cut and coagulate tissue thereby reducing patient risk and damage to tissue.
