A device for preventing air escape and maintaining colonic air distension can include a body, a distal gasket coupled to a distal end of the body, a proximal gasket coupled to a proximal end of the body, and a diaphragm coupled to the proximal gasket. The distal and proximal gaskets can form a fluid-tight seal with a colonoscope positioned within central bores of the distal gasket, the body, and the proximal gasket, and the diaphragm can conform to and form a fluid-tight seal with at least one of an anus and a stoma of a subject.

An endoscope (1) including a handle (2) arranged at a proximal end and an insertion tube (3) extending from said handle (2) towards a distal end, a bending section (7) arranged at the distal end and controllable by and operator via control input means (8) arranged at the handle (2); and at least one insertion tube part with at least one lumen, wherein the bending section (7) is displaceable in said lumen so as to be movable relative to the insertion tube (3) from a retracted position within said lumen to an extended position at least partially outside said lumen.

A surgical device comprises an elongate shaft (12) which extends from a proximal end region to a distal end region thereof, the shaft (12) defining a first lumen (14) for receiving an elongate camera device therein, a second lumen (16) for receiving a tissue manipulation device therein, and a third lumen (18) for receiving a tissue retrieval device therein, the first, second and third lumens (14, 16, 18) extending from the proximal end region to the distal end region of the elongate shaft, and having respective open ends at the distal end region of the elongate shaft. The surgical device further comprises an elongate camera device which extends along the first lumen, a tissue manipulation device which extends along the second lumen, and a tissue retrieval device which extends along the third lumen.

An endoscope may include a needle and a scope, which may optionally be contained in an elongated shaft. The endoscope may further include a handle comprising at least one button, a visualization component, a reservoir configured to contain a composition, and a dispensing mechanism. The at least one button, the needle, the reservoir, and the dispensing mechanism may be operably linked to cause the composition to be dispensed from the reservoir through the needle to a portion of an ear. A method for using such an endoscope may include inserting the endoscope into a portion of an ear, using the visualization component to visualize the portion of the ear, and pressing the at least one button to dispense the composition from the reservoir through the needle to the portion of the ear.

An ultrasound device includes an ultrasound body having a shaft and an ultrasound sensor assembly disposed at a distal end portion of the shaft. The ultrasound sensor assembly is configured to enable ultrasound imaging. A clip is configured for positioning about a portion of a surgical tool. The clip is configured to releasably engage the ultrasound body to thereby releasably couple the surgical tool with the ultrasound body. A surgical system includes the ultrasound device and the surgical tool.

The present disclosure relates generally to the field of medical devices. In particular, the present disclosure relates to devices and methods to guide delivery devices and instruments. Exemplary instrument guides, including for endoscopes as delivery devices for cryogen delivery catheters and to guide cryogen decompression tubes as instruments, and methods for use of such instrument guides for use in body lumens at treatment sites, are disclosed.

An intraoral imaging apparatus, a medical apparatus, and a program capable of providing auxiliary data for determination regarding diseases having differences in intraoral findings are provided. The intraoral imaging apparatus includes: an imaging device that acquires an intraoral image; a light source that emits light to a subject of the imaging device; a storage apparatus that stores an algorithm for performing determination of a specific disease; and an arithmetic apparatus, in which the arithmetic apparatus executes: a determination process of determining a possibility of the predetermined disease based on the image and the algorithm; and an output process of outputting a result of the determination process.

The stent delivery system includes: an outer tube in which a first opening is formed in a distal end and a second opening is formed between the distal end and a proximal end; an inner tube inserted into the outer tube from the first opening to the second opening, and disposed outside of the outer tube from the second opening to the proximal end of the outer tube; and a stent stored between the inner tube and the outer tube. The outer tube and the inner tube are configured to be inserted into a channel of an endoscope. The second opening is formed at a position where the second opening is arranged inside the channel when a storage position is protruded from a distal end side of the channel.

A medical device includes an elongate device and one or more processors coupled to the elongate device. The elongate device includes a steerable distal end and a shape sensor located along a length of the elongate device. While the elongate device is being traversed through one or more passageways of a patient, the one or more processors are configured to, based on information from a sensor, monitor an insertion motion of the elongate device, detect a data collection event, and capture, in response to detecting the data collection event, a plurality of points along the length of the elongate device using the shape sensor. The data collection event is at least partially based on a change in direction of the insertion motion of the elongate device.

Connectors for connecting or linking one instrument or object to one or more other instruments or objects are disclosed herein. In some embodiments, a connector can include a first arm with a first attachment feature for attaching to a first object, such as a surgical access device, and a second arm with a second attachment feature for attaching to a second object, such as a support. The connector can have an unlocked state, in which the position and orientation of the access device can be adjusted relative to the support, and a locked state in which movement of the access device relative to the support is prevented or limited. Locking the connector can also be effective to clamp or otherwise attach the connector to the access device and the support, or said attachment can be independent of the locking of the connector.
