Abstract: A tissue collection instrument comprises a tissue separator device comprising a separator and a storage volume, and a tissue retrieval device comprises a tissue shuttle storable in the storage volume and a retriever connected to the tissue shuttle to retract the tissue shuttle away from the tissue separator device. A method of collecting biological matter using a tissue collection instrument comprises inserting a tissue separator device into anatomy. operating the tissue separator device to obtain a first tissue sample from the anatomy. collecting the first tissue sample with a shuttle associated with the tissue separator device and withdrawing the shuttle from the anatomy. A method of collecting biological matter comprises assembling a tissue separator with a scope, inserting the scope and the tissue separator into anatomy. operating the tissue separator to obtain a tissue sample. and withdrawing the tissue sample through an openable lumen in the scope.

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 forceps can include a first jaw and a second jaw. The first jaw can include a first jaw frame and a first movable jaw segment coupled with the first jaw frame. The second jaw can be coupled with the first jaw and the first movable jaw segment can be in communication with a first electromagnetic actuation system. The first movable jaw segment is configured to be electromagnetically actuatable relative to the first jaw frame.

Abstract: An endoscope can comprise a proximal section, an insertion section extending longitudinally from the proximal section and comprising an elongate tubular body disposed along an insertion section longitudinal axis and a lumen extending through the elongate tubular body, and a distal section extending from the insertion section and comprising an elevator portion comprising an elevator configured to position and orient one or more endotherapy tools extending from the lumen, and a camera module comprising an illumination unit and an imaging unit. The camera module can be positioned longitudinally spaced apart from the elevator portion in an in-line configuration, such that the insertion tube longitudinal axis passes through the elevator portion and the camera module. The camera module can be user-detachable from the elevator portion. The camera module can be cleaned and sanitized for reuse and the insertion section can be disposable.

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: A forceps having at least a first jaw with a longitudinal axis is disclosed. The first jaw can include a body portion, a first flange, a second flange and a cam pin. The first flange can define a first cam slot with a longitudinal extent along the longitudinal axis. The second flange can be spaced from the first flange a distance transverse to the longitudinal axis of the first jaw and can have a second cam slot. The cam pin, with a longitudinal axis, can be moveably secured within the first cam slot and the second cam slot. A diameter of the cam pin can be less than a width between a first longitudinal edge that defines a first side of each of the first cam slot and the second cam slot and a second longitudinal edge that defines a second opposing side of each of the first cam slot and the second cam slot so that the cam pin is moveably received by both the first cam slot and the second cam slot. With the first jaw pivoted to at least a first position, the cam pin and first flange can be configured such that the first longitudinal edge is contacted by the cam pin but the second longitudinal edge is spaced from the cam pin. The cam pin and second flange can be configured such that the first longitudinal edge is spaced from the cam pin but the second longitudinal edge is contacted by the cam pin.
