An ablation instrument comprises an elongate shaft having a cannula channel and a scope channel, and an electrode disposed in the cannula channel. The electrode is slidable between a first position in which a distal end of the electrode is contained within the cannula channel, and a second position in which the distal end of the electrode extends out of a distal opening of the cannula channel. The ablation instrument further comprises a distal head coupled to the elongate shaft and configured for contacting solid tissue.

An endoscope based system is configured to provide one or more procedure guidance features. The endoscope is paired with an image processing device that performs object detection and other analysis on captured images, and displays an interface to users that includes various visual guidance combined with endoscopic images. Interfaces displayed in different modes may indicate the location and extent of energy delivery tracked by the system, may guide placement of implant devices, may identify the location of nerves within tissue, and may provide step-by-step guidance for navigating the endoscope to certain anatomy. In some implementations, a removable and replaceable sheath may be coupled to the endoscope, and may enable one or more functional features of the endoscope while maintaining a sterile barrier. Sheaths may include an embedded memory that stores procedure configurations and procedure results.

A system and method for providing relative positional information of a therapeutic or diagnostic device during the treatment of urinary tract diseases and conditions.

A body orifice remodeling device includes a cylindrical handpiece having a defined length which is adapted to be inserted into the body orifice and an elongated monopolar electrode mounted outside on the circumference of the cylindrical handpiece and extending substantially along the length of the handpiece. A source of radio frequency (RF) energy in the handpiece is configured to generate RF energy to the elongated monopolar electrode; and a source of electromagnetic stimulation energy (EMagS) in the handpiece is configured to generate (EMagS) energy.

A system for controlling ablation treatment and visualization is disclosed where the system comprises a tissue ablation instrument having one or more deployable stylets and a first electromagnetic sensor and an ultrasound imaging instrument which may be configured to generate an ultrasound imaging plane and further having a second electromagnetic sensor. An electromagnetic field generator may also be included which is configured for placement in proximity to a patient body and which is further configured to generate an output indicative of a position the first and second electromagnetic sensors relative to one another. Also included is a console in communication with the ablation instrument, ultrasound imaging instrument, and electromagnetic field generator, wherein the console is configured to generate a representative image of the tissue ablation instrument oriented relative to the ultrasound imaging plane and an ablation border or cage based upon a deployment position of the one or more stylets.

A system is provided to treat sleep apnea, with a method of use. The system includes a handpiece which includes at least one penetrating electrode configured to penetrate tissue and one or more temperature sensors. A processor is coupled with the one or more temperature sensors and the at least one penetrating electrode, and a memory is configured to store instructions executable by the processor. The instructions, when executed, are operable to emit, by the at least one penetrating electrode, RF energy from the electrodes to heat a region of a base of a tongue until a target energy is delivered to the region. The instructions are also operable to measure, by the one or more temperature sensors, the temperature of the region.

Method and apparatus for treating peripheral olfactory dysfunction are described herein. One method may include introducing a treatment device into a nasal cavity of the patient, the treatment device having a proximal end, a distal end, an elongated shaft therebetween, and a treatment end effector disposed on or near the distal end. The distal end of the treatment device may be advanced into proximity of a cribriform plate within the nasal cavity and at least one olfactory neuron may be ablated through the cribriform plate via the treatment end effector to reduce at least one symptom of olfactory dysfunction.

Disclosed herein is an electrosurgical device including a handle at a proximal end and an elongate shaft coupled to the handle and extending distally from the handle. The device also includes a distal working end, including a return electrode and an active electrode supported by an insulative spacer, the insulative spacer separating the return and active electrode. The active electrode has a planar surface that is distal facing and defines a maximum planar surface length. The insulative spacer is generally tapered between the return electrode and active electrode. The insulative spacer has a planar stabilizing surface on a device first side that has a length that extends along the longitudinal axis, extending from a distal-most end of the return electrode to a leading edge surface of the active electrode. This length is at least as long as the maximum planar surface length.

A colpotomy device includes a shaft assembly having a hollow outer shaft and an inner shaft disposed within, and rotatable and translatable relative to, the outer shaft, a handle assembly operably coupled to a proximal end of the shaft assembly, and configured to selectively rotate the inner shaft relative to the outer shaft, a colpotomy cup assembly including an outer cup and an inner cup disposed within the outer cup, wherein the inner cup is fixedly coupled to a distal end of the inner shaft, and the outer cup is fixedly coupled to a distal end of the outer shaft, and a cutting element coupled to the inner cup, such that the inner shaft the shaft assembly, inner cup, and cutting element rotate together relative to the outer shaft.

According to one aspect of the present disclosure, a medical device may include a shaft assembly. The shaft assembly may include a sheath having a first lumen. The shaft assembly may also include a rotatable shaft extending through the first lumen. The rotatable shaft may be rotatable relative to the sheath, and may have a second lumen and a side opening. The shaft assembly may also include an electrode extending through the second lumen and the side opening, and radially outwardly from the rotatable shaft. The electrode may be movable relative to the rotatable shaft.
