A medical apparatus includes a treatment device configured to be capable of treating a subject by applying energy to the subject, an optical fiber including a light emitting face for emitting light into the subject, the optical fiber being connected to the treatment device, and a shield portion that is disposed in front of the light emitting face of the optical fiber, the shield portion being configured to expose the light emitting face when the treatment device does not perform a treatment operation and to shield the light emitting face when the treatment device performs the treatment operation.

An ophthalmic speculum includes arms, a locking mechanism, and an air-flow system. The arms include a first arm and a second arm. Each arm has a retractor shaped to conform to an eyelid of a pair of eyelids of an eye. The retractors are substantially symmetrical about a lateral axis. The locking mechanism is coupled to the arms. The locking mechanism moves the arms to allow the retractors to retract the pair of eyelids, and fixes the arms into place to maintain retraction of the pair of eyelids. The air-flow system is coupled to at least one arm, and moves air in a region disposed outwardly from a surface of the eye.

A vapor delivery system and method is provided that is adapted for ablating bladder tissue to treat overactive bladder (OAB). The vapor delivery system includes an anchor tip configured anchor the system in the bladder while condensable vapor is delivered to target tissue. In one method, the vapor delivery system is advanced transurethrally into the patient to access the target tissue of the bladder, which can include a surface sensor of the bladder responsible for creating an urge incontinence sensation. The vapor delivery system includes a vapor source that provides a high quality vapor for delivery to tissue.

Provided herein are devices, systems and methods utilizing flow of a medically safe inert gas to prevent fires in operating rooms during electrosurgical procedures. A device is disposed around or proximate to or integrated into the tip of an electrosurgical instrument or tool and is in fluid contact with a source of a medically safe inert gas. The gas is flowed around or envelopes the tip as the electrosurgical instrument or tool is utilized. The presence of the medically safe inert gas displaces oxygen, thereby preventing or suppressing fires that may be ignited by sparks generated during use of the tool.

Ultrapolar non-telescopic electrosurgery pencil with argon beam capability which is capable of using monopolar energy in a bipolar mode for cutting and coagulation and which is also capable of using an ionized gas for cutting and coagulation. The ultrapolar non-telescopic electrosurgery pencil with argon beam capability includes a handpiece member, an electrosurgery blade assembly positioned within an end of the handpiece member where the electrosurgery blade assembly includes a blade having a non-conductive sharp cutting edge, a return electrode, and an active electrode, and a non-conductive hollow tube member positioned over a top of the blade and at least a portion of the return electrode, a first conductive hollow tube having at least a portion concentrically contained within the non-conductive hollow tube member of the electrosurgery blade assembly, a flexible non-conductive tube contained within at least a portion of ultrapolar non-telescopic electrosurgery pencil which provides a gas to the first conductive hollow tube, and a plurality of electrical conductors for connecting the return electrode, the active electrode, and the first conductive hollow tube to an RF electrosurgical generator for activating the ultrapolar non-telescopic electrosurgery pencil.

A method for controlling gas composition in a surgical cavity during an endoscopic surgical procedure includes monitoring for a plurality of gas species in a gas flow from a surgical cavity of a patient. The method includes measuring the plurality of gas species in the gas flow from the surgical cavity and determining if the gas species measured in the gas flow from the surgical cavity are each present and/or within a respective desired range. The method includes adding gas into the surgical cavity if one or more gas species in the plurality of gas species is outside of the respective desired range so as to bring a composition of gas species in the surgical cavity within the respective desired range.

An energy delivery probe is provided that may include any of a number of features. One feature of the energy delivery probe is that it can apply energy to tissue, such as a prostrate, to shrink, damage, denaturate the prostate. In some embodiments, the energy can be applied with a vapor media. The energy delivery probe can include a vapor delivery member configured to extend into a transition zone prostate tissue. A condensable vapor media can be delivered from the vapor delivery member into the transition zone tissue, wherein the condensable vapor media can propagate interstitially in the transition zone tissue and be confined in the transition zone tissue by boundary tissue adjacent to the transition zone tissue. Methods associated with use of the energy delivery probe are also covered.

A surgical robotic system comprising: a robotic arm; a tool drive coupled to the robotic arm; a cannula interface configured to couple a cannula to the tool drive, the cannula interface having a fluid pathway in communication with an interior lumen of the cannula; and an insufflation pathway coupled to the robotic arm, the insufflation pathway having a distal end coupled to the fluid pathway and a proximal end coupled to a surgical insufflator.

A vapor delivery system and method is provided that is adapted for ablating bladder tissue to treat overactive bladder (OAB). The vapor delivery system includes an anchor tip configured anchor the system in the bladder while condensable vapor is delivered to target tissue. In one method, the vapor delivery system is advanced transurethrally into the patient to access the target tissue of the bladder, which can include a surface sensor of the bladder responsible for creating an urge incontinence sensation. The vapor delivery system includes a vapor source that provides a high quality vapor for delivery to tissue.

An endoscopic treatment device includes a hollow tube; an electrode; and an insulative support member. In a radial direction relative to a longitudinal axis of the hollow tube, the insulative support member is radially outward of the electrode and the hollow tube is radially outward of the insulative support member.
