Abstract: A device for performing a surgical procedure can comprise a shaft extending from a proximal portion to a distal portion, a light conductor extending at least partially through the shaft to be exposed at the distal portion, and a damage mitigator positioned to receive light from the light conductor to discharge the light from the device. A method of preventing damage to an optical fiber in a medical device having laser treatment capabilities can comprise emitting a laser beam from the optical fiber, fragmenting a biological stone with the laser beam, and mitigating damage to the optical fiber from fragmentation of the biological stone.

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.

Abstract: A tissue separation device can comprise an elongate body comprising a proximal end portion and a distal end portion, a tissue separator coupled to the distal end portion, the tissue separator configured to engage sample tissue for retrieval, and a pressure-applying device configured to bias the tissue separator against the sample tissue. A method of collecting biological matter using a tissue retrieval device can comprise inserting the tissue retrieval device into anatomy of a patient, guiding a tissue collector of the tissue retrieval device to a target tissue area, activating a pressure applying device to bias the tissue collector into the target tissue, and collecting biological matter with the tissue retrieval device.

Abstract: A surgical instrument for removing biological tissue during a surgical procedure comprises an elongate shaft and an end effector connected to the elongate shaft, the end effector including an edge configured to remove tissue, wherein curvature of one or both of the elongate shaft and end effector is adjustable to position the edge along a tissue surface when the curvature of the one or both of the elongate shaft and end effector is adjusted. A method of incising target tissue from an anatomic wall comprises inserting a shaft of a surgical instrument into an anatomic chamber of a patient, positioning a tissue-removal device connected to the shaft proximate the target tissue, deflecting an axis of the tissue-removal device relative to a central axis of the shaft, and shaving a surface of the anatomic wall by moving the tissue-removal device in a deflected state along the target tissue.

Abstract: Disclosed herein is a vapor therapy device for producing intra-uterine tissue effects. The device can include a shaft, including a proximal portion and a distal portion, a fluid-expandable medium, near the distal portion of the shaft, a fluid-delivery conduit, extending between the proximal portion and the distal portion of the shaft, the fluid-delivery conduit comprising an outlet, near the distal portion of the shaft, for delivery of the fluid toward the medium, and an in vivo heat generator, near the distal portion of the shaft, to heat the fluid. A method of treating a patient for menorrhagia with the device can include introducing a medium, in a contracted state, into a patient, delivering a fluid toward the medium to expand the medium in vivo; generating heat in vivo on or near the medium to vaporize the fluid, and exposing a treatment site to the vaporized fluid.

Abstract: The teachings herein provide an instrument comprising a forceps. The forceps comprise a hand piece; a tubular member connected to the hand piece; and a jaw assembly connected to the hand piece. The jaw assembly includes a first jaw element and a second jaw element. The first jaw element includes a gripping section and a flexing section. The flexing section includes an arcuate section. The second jaw element opposes the first jaw element and includes a gripping section. The tubular member is moveable onto the arcuate section of the first jaw clement so that the flexing section of the first jaw element is flexed and the jaw assembly is moved into a closed position. The first jaw element, the second jaw element, or both include a stiffening spine so that the jaw assembly is substantially rigid in the closed position.
