Technologies are described for an endoscopic duct clearing system. A cannula can be shaped to pass through an endoscope within an esophagus, into a duodenum, and through an incision in a duodenal papilla. A capture basket may be deployed from a distal end of the cannula. A hand control at the proximate end of the cannula may be operable to position the distal end of the cannula from outside the endoscope into proximity of blockage material. A suction line may be coupled from a suction source to the proximate end of the cannula. A suction control may be coupled to the suction source. The suction control may be operable to adjust a level of suction drawn by the suction source through the distal end of the cannula. The suction control may be adjusted to draw the blockage material against or into the cannula for removal from the patient.

A fixture for a fluoroscopic x-ray imaging system is discussed, wherein the fluoroscopic imaging system includes a C-arm, an x-ray source at a first end of the C-arm, and an x-ray detector at a second end of the C-arm. The fixture includes a processor and memory coupled with the processor. The memory includes instructions that are executable by the processor so that the processor is configured to detect an x-ray emission from the x-ray source toward the x-ray detector, determine an offset of the x-ray source relative to the x-ray detector responsive to detecting the x-ray emission, and provide an indication of the offset of the x-ray source to a medical navigation system. Related methods and robotic systems are also discussed.

A multi-portal method for treating a subject's spine includes distracting adjacent vertebrae using a distraction instrument positioned at a first entrance along the subject to enlarge an intervertebral space between the adjacent vertebrae. An interbody fusion implant can be delivered into the enlarged intervertebral space. The interbody fusion implant can be positioned directly between vertebral bodies of the adjacent vertebrae while endoscopically viewing the interbody fusion implant using an endoscopic instrument. The patient's spine can be visualized using endoscopic techniques to view, for example, the spine, tissue, instruments, and implants before, during, and after implantation, or the like. The visualization can help a physician throughout the surgical procedure to improve patient outcome.

A surgical system for performing a capsulotomy of a lens capsule of an eye includes an elastic ring, a suction cup, an interface, a converter, and a control console. The elastic ring includes a conductive surface. The interface may be coupled to an air port and/or a fluid line of a phacomachine. The converter detects a pulse of air from the phacomachine via the interface, and produce an electrical signal in response. Fluid received from the phacomachine is delivered into the suction cup. The system is configured to remove the fluid from the suction cup and between the suction cup and a surface of the eye to form a suction seal. The control console is configured to, in response to receiving the electrical signal, drive a series of electrical pulses through the conductive surface of the elastic ring, causing the elastic ring to perform a tissue cutting operation.

Aspects of the present disclosure are presented for managing simultaneous outputs of surgical instruments. In some aspects, methods are presented for synchronizing the current frequencies. In some aspects, methods are presented for conducting duty cycling of energy outputs of two or more instruments. In some aspects, systems are presented for managing simultaneous monopolar outputs of two or more instruments, including providing a return pad that properly handles both monopolar outputs in some cases.

Devices to control a movement or instrument function of a robotic arm of a surgical robotic system include a foot pedal configured to generate a first input signal when the foot pedal is moved to a first activation position and a second input signal, different from the first input signal, when the foot pedal is moved to a second activation position. The first activation position may be associated with a first specific movement or instrument function of a robotic arm. The second activation position may be associated with a second specific movement or instrument function of the robotic arm. The foot pedal is configured to send the first input signal or the second input signal to a surgical console to be utilized to remotely control the respective specific movement or instrument function of the robotic arm.

An interactive control unit is disclosed. The interactive control unit includes an interactive touchscreen display, an interface configured to couple the control unit to a surgical hub, a processor, and a memory coupled to the processor. The memory stores instructions executable by the processor to receive input commands from the interactive touchscreen display located inside a sterile field and transmit the input commands to the surgical hub to control devices coupled to the surgical hub located outside the sterile field.

Provided herein are dual-lumen catheters, systems, and methods thereof. In some embodiments, for example, a catheter assembly configured for modifying intravascular lesions is provided including a core wire, a dual-lumen extrusion including the core wire, and a manifold disposed around a portion of the dual-lumen extrusion. The core wire includes a proximal end configured to vibrationally couple to an ultrasound transducer. The dual-lumen extrusion includes a first lumen and a second lumen. The core wire is disposed within the first lumen, and the second lumen is configured to accommodate a guidewire. The manifold is disposed around at least a skived proximal-end portion of the dual-lumen extrusion, wherein the skived portion includes the second lumen without the first lumen. In some embodiments, the catheter assembly further includes the ultrasound transducer. In some embodiments, a system console includes the ultrasound transducer.

An arthroscopic cutting probe includes an elongated shaft assembly having a distal end, a proximal end, and a longitudinal axis therebetween. A working end at the distal end of the elongated shaft assembly includes a first active electrode and a second active electrode The shaft assembly is rotates the first electrode relative to the second electrode about the longitudinal axis, and a return electrode is carried on the shaft assembly proximal of the working end. The first and second active electrodes are electrically coupled to each other and electrically isolated from the return electrode.

A medical system includes an insertion device including a handle and a delivery portion, a laser fiber, a conductive wire, and a lock. The laser fiber extends through the insertion device and is coupled to a laser slider to control a position of the laser fiber relative to a distal end of the delivery portion. The conductive wire extends through the insertion device and is coupled to a wire slider to control a position of the laser fiber relative to a distal end of the delivery portion. The lock is positioned within the handle and is movable in order to selectively lock either the movement of the laser slider or lock the movement of the wire slider.
