Abstract: An instrument including a first arm, a second arm, and a blade. The first arm includes a lumen in communication with a source of irrigation fluid and one or more outlets in communication with the lumen for delivering the irrigation fluid to a surgical site. The instrument is switchable between a first configuration and a second configuration. In the first configuration, the instrument is configured to deliver a first therapy current through a distal end of the first arm, a distal end of the second arm, or both. In the second configuration, a distal end of the blade extends beyond the distal end of the first arm and beyond the distal end of the second arm.

Abstract: An adapter for an endoscope system comprises a housing, a light conducting element, a sensor to receive light waves emitted from the light conducting element, a converter connected to the sensor to convert light waves into an electrical signal comprising instructions for generating light with a light generator of an endoscope, and an electrical coupler connected to the converter to convey the electrical signal out of the housing to the endoscope. A method for communicating light control signals from an imaging and control system to an endoscope having light generating capabilities comprises generating light with a light generator, receiving light from the light generator at an adapter, sensing an intensity of light with a sensor, converting the intensity sensed by the sensor to light control signals for generating light with a light generator of the endoscope, and transmitting the light control signal to the light generator of the endoscope.

Abstract: An endoscope comprises a handpiece housing, an elongate flexible shaft extending from the handpiece housing, a pull wire extending from the handpiece housing into the elongate flexible shaft, and a tensioning mechanism configured to adjust tension in the pull wire. A method for adjusting tension in a pull wire of a controller for an endoscope comprises preparing an endoscope for use before a procedure, adjusting tension in a pull wire for deflecting a flexible elongate shaft of the endoscope to reduce knob dwell, and performing an endoscopic procedure with the endoscope.

Abstract: Forceps with improved actuation include a housing and a body that is longitudinally slidable relative to the housing. The body having a peripheral flange extending outward towards the housing. A trigger includes an actuation surface configured to receive a force input from a user. The trigger further including at least one arm configured to transfer the received force input to the body. To inhibit lateral splaying of the at least one arm when the trigger is actuated, the housing includes a first control surface, such as a rib proximate the arm.

Abstract: Apparatus and associated methods relate to controlling electrical power of an electrotherapeutic signal that is provided to a biological tissue engaged by an electrosurgical instrument during a medical procedure. Electrical power—a product of a voltage difference across and an electrical current conducted by the engaged biological tissue—is controlled according to a therapeutic schedule. The electrotherapeutic schedule can be reduced or terminated in response to a termination criterion being met. In some examples, the termination criterion is a current characteristic, such as, for example, a decrease in current conducted by the engaged biological tissue. In some examples, the termination criterion is a biological tissue resistance characteristic, such as, for example, an increase in the biological tissue resistance that exceeds a predetermined delta resistance value.

Abstract: A direct peroral cholangioscope system comprises a guide sheath sized to pass through an esophagus of a patient comprising a proximal end portion, a distal end portion, and a lumen extending between the proximal end portion and the distal end portion, an endoscope comprising an elongate body extending from a proximal end to a distal end, an imaging device coupled to the elongate body proximate the distal end, and a passage extending at least partially through the elongate body and exiting at the distal end, the elongate body sized to pass through the lumen, and a tissue retrieval device configured to pass through the passage and retrieve tissue from within the patient. The guide sheath can be used to steer the endoscope through the pyloric sphincter and the sphincter of Oddi to allow the endoscope to be articulated in the common bile duct using native steering capabilities.
