摘要： A surgical forceps can include a first shaft, a cam feature, a first jaw, a second jaw, an actuator arm, and a second shaft. The cam feature can be connected to the first shaft. The first jaw can define a cam interface and an actuator track. The cam interface can be engaged with the cam feature, and the first jaw can be movable between an open position and a closed position. The first jaw can be movable relative to the second jaw. The actuator arm can include a distal portion configured to apply a closing force on the first jaw when the first jaw is moved out of the open position. The second shaft can move the cam interface along the cam feature to move the first jaw between the open position and the closed position.

摘要： Disclosed embodiments include apparatuses, systems, and methods for facilitating anastomosis between bodily passages. In an illustrative embodiment, an eversion mechanism is configured to engage a first external surface of a receiving passage adjacent a first opening in the receiving passage in order to create a receiving flange presenting a first interior face. A donor support mechanism is configured to support a donor passage with an opening in an end in an everted position that forms a donor flange presenting a second interior face. The donor support mechanism is further configured to present the second interior face of the donor flange against the first interior face of the receiving flange to present a passage juncture. A suturing mechanism is configured to motivate a filament through a helical path around the passage juncture to suture the second interior face of the donor passage to the first interior face of the receiving passage.

摘要： A system to deliver energy to treat a mobile calculus, the system can include a drill and a lateral energy emitter. The drill can be configured to drill a recess into the mobile calculus or a passage through the mobile calculus. The lateral energy emitter can be configured to be advanced into the recess or the passage and to transmit the energy internal to the mobile calculus to fragment the mobile calculus. In some examples, the system can include a deployable capture portion to constrain a stone relative to the capture portion.

摘要： A valve loading system that uses a valve loader to transfer a valve or other medical device from a storage cartridge into a deployment catheter. The valve or other medical device can be implanted or positioned within a patient using the catheter after the valve or other medical device has been compressed and loaded into the catheter using the valve loader. The process then can be repeated by using the valve loading system to load or introduce another valve or other medical device into the catheter. The valve loading system includes a loading pin sized to limit contact with the medical device during a loading procedure.

摘要： Systems and techniques for nerve monitoring are described herein. The system can include a remote transmitter configured to send a stimulation signal to a nerve, and an electrosurgical device including an end effector configured to perform a surgical function in response to receiving a therapeutic signal from an electrosurgical generator. The system can also include a receiver configured to detect the stimulation signal, and in response to detecting the stimulation signal, determine a location of the nerve, and an in-vivo transmitter configured to emit a location signal in response to the determined location of the nerve.

摘要： Disclosed embodiments include apparatuses, systems, and methods for positioning electrodes within a body. In an illustrative embodiment, an apparatus for slidably moving multiple features relative to a sheath inserted into a body and positioned relative to a reference point includes a primary actuator configured to move a primary electrode, a secondary actuator configured to move a secondary electrode, and a control mechanism. The control mechanism is configured to selectively prevent movement of at least one of the primary actuator based on a position of the secondary actuator and of the secondary actuator based on a position of the primary actuator and lock positions of the primary actuator and the secondary actuator.

摘要： A guiding probe for identifying a location within an anatomical region of a patient. The guiding probe can optionally: a graspable portion, an insertion portion and an emitter. The insertion portion can be coupled to the graspable portion. The insertion portion can have an elongated extent and a longitudinal axis. The insertion portion can include a flexible section and a bending section. The bending section can be positioned distal of the flexible section. The emitter can be coupled to a distal end portion of the insertion portion. The emitter can be configured for use within the anatomical region to emit a signal that can be detectable extracorporeally of the patient whereby the signal enables the location within the anatomical region to be identified extracorporeally for therapy to be applied.

摘要： Disclosed embodiments include apparatuses, systems, and methods for positioning electrodes. In an illustrative embodiment, an apparatus includes a primary electrode defining a lumen, an elongated secondary electrode slidably receivable within the lumen, and a sheath configured to slidably receive the electrodes and to convey the electrodes toward a target region. A housing is coupled with the sheath and movably mounted to motivate the sheath relative to the target region. A primary actuator is coupled with the primary electrode and slidably coupled with the housing to motivate the primary electrode relative to the sheath. A secondary actuator is coupled with the secondary electrode and movably coupled with the primary actuator to be slidable with the electrodes in concert. The secondary actuator is rotatable independently of the primary actuator to travel along a helical path to motivate the secondary electrode to move relative to the target region independently of the primary electrode.
