A system for controlling operation of a radiofrequency treatment device to apply radiofrequency energy to tissue to treat tissue to create lesions without ablating the tissue. The system includes a first treatment device having a plurality of electrodes. The electrodes are maintained in axial alignment and fixed radial spacing in retracted and extended positions. The device includes a basket having a plurality of arms. The arms are maintained in a fixed radial spacing in the collapsed position of the basket.

A device for applying an insulating sleeve to an electrosurgical instrument, the device comprising a housing, the housing comprising: a first end; a second end; a hollow channel extending from the first end to the second end, the channel being configured to receive an electrosurgical instrument comprising an end effector connected to a shaft by a distal articulation; a support structure internal to the housing; the support structure being configured to: support an insulating sleeve such that the insulating sleeve surrounds the electrosurgical instrument when the electrosurgical instrument is received by the channel; and when the electrosurgical instrument is advanced through the channel from the first end to the second end, release the insulating sleeve onto the electrosurgical instrument.

Embodiments disclosed herein include devices and methods of using devices for protecting a face and/or head of an individual receiving medical treatment in a supine or reclined position. The device includes a body having a top portion with an exterior surface and a base portion with an interior surface. The top portion includes opposing side edges, the base portion includes opposing bottom side edges extending outwardly from the top side edges. The base portion is flexible and is configured to wrap partially around the individual’s head, while an aperture extends between the exterior surface and the interior surface to provide access to at least one of the individual’s eyes, nose, or mouth. A strap spans the side edges, wraps behind the base portion and the individual’s head, and detachably couples to the exterior surface along a plurality of connection positions along the side edges.

Disclosed is an implant intended to be introduced into a human or animal body cavity, and includes two walls intended to grip between them a biological protuberance present in the cavity in order to attach the implant to the biological protuberance. Each wall includes a structural element having corrugations such that the structural element is folded up on itself several times, enabling the wall to be folded up before the introduction of the implant, then deployed inside the cavity.

Devices, systems, and methods for a robot-assisted surgery. Navigable instrumentation, which are capable of being navigated by a surgeon using the surgical robot system, and navigation software allow for the navigated placement of interbody fusion devices or other surgical devices. The interbody implant navigation may involve navigation of access instruments (e.g., dilators, retractors, ports), disc preparation instruments, trials, and inserters.

A tissue guard for use with a surgical access device includes a body having a proximal end, a distal end and lumen defined therebetween. A proximal lip extends radially from the proximal end and is configured to mount atop a rim of an access device. The proximal lip includes an annular channel defined therein disposed in fluid communication with the lumen, the annular channel configured to direct surgical gases from the lumen to a smoke evacuation system. The annular channel includes a neck defined therein disposed between the lumen and the annular channel, the neck having geometry configured to induce the evacuation of surgical gases or smoke therethrough. One or more fingers extend from the proximal lip and are configured to engage an access device to secure the tissue guard thereon.

A balloon is provided for selectively moving an esophagus away from an ablation site. The balloon is received through an oral cavity and into the esophagus of a patient. A deflecting member is provided in the tube, the balloon, or both, to selectively distort to bend the balloon and/or the tube to move the esophagus away from the ablation site. The deflecting member may comprise at least one of a strip made of a shape memory material that is responsive to the receipt of a stimulus to deflect to a predetermined shape, a strip that is made of or contains a ferrous material and that deflects in response to the presence of a magnetic field, and a selectively tensionable cable, wire, or string. The deflecting member may be supplemented by a stiffening strip that is located in the balloon and that causes the balloon to expand circumferentially and asymmetrically when inflated.

Assemblies, systems, and methods are directed at a neuromonitoring bone drill bit. The assembly may include a surgical bone drill bit, a neuromonitoring connection in electrical communication with the drill bit, and a shield extending over a distal end of the drill bit. The shield may be configured to withdraw proximally as the drill bit is advanced into a subject's bone. The assembly may be connected to a surgical drill and used in a surgical spinal procedure. In operation, the assembly may be advanced to a subject's bone at a surgical site and the drill bit may rotate into the subject's bone. In response, the shield may engage the bone and the drill bit may be advanced with respect to the shield. The shield may electrically insulate tissue from electrical current passing through the drill bit as it is inserted at the surgical site.

A surgical guide and methods of using the surgical guide are disclosed. The surgical guide includes a body having a first side and a second side. An adhesive material is disposed over at least a portion of the first side. A radiopaque guide element coupled to a second side of the body and an incision guard defines an opening extending from the first side to the second side of the body. The incision guard is sized and configured to receive a surgical instrument therethrough such that the incision guard prevents contact between the surgical instrument and a portion of a surgical site adjacent to the opening.

An ophthalmic surgical system can include a light source configured to generate a light beam and a filter wheel disposed between the light source and an intraocular illumination device. The filter wheel can include an unfiltered area, a first filtered area, and a second filtered area. The first and second filtered areas can limit transmission of certain wavelengths of the light beam to the intraocular illumination device. The system can include an actuator configured to selectively move the filter wheel to cause the light beam to pass through the unfiltered area, the first filtered area, and/or the second filtered area. The system can include a computing device configured to provide a control signal to the actuator. The computing device can be configured to provide a control signal to the actuator based on a beam location, a beam composition, an exposure time, and/or a limited visibility condition.
