The present disclosure relates to a cap for protecting an imaging instrument from damage caused by impact or poor handling. Exemplary devices can include a rigid outer shell and soft inner lining surrounding a distal tip of the instrument, to be applied between instrument use, and during instrument transport, disinfection, sterilization, and storage.

Fluorescent imaging systems for performing an endoscopic procedure, such as a retrograde cholangiopancreatography (ERCP) procedure may include a first light source for emitting light in the visible spectrum, or light in the near infrared (NIR) spectrum, or both. A light source bandpass filter may block the emitted light in the visible spectrum, or in the NIR spectrum, or both. A first sensor may be capable of detecting the light in the visible spectrum, or the light in the NIR spectrum, or both. A sensor bandpass filter may block the detected light in the visible spectrum, or in the NIR spectrum, or both. The first or a second light source, or the first or a second sensor, or combinations thereof, may be removably disposed on a duodenoscope.

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.

Described herein is a video laryngoscope apparatus for inspection of an oral cavity region of a patient is disclosed. The video laryngoscope includes an apparatus body, a camera arm unit configured to receive and releasably attach thereto a disposable laryngoscope blade, a light source coupled to the camera arm unit, a communication unit, and a power source. The apparatus body includes a proximal end and a distal end, and the apparatus body is elongate and configured to be hand-held by an operator of the video laryngoscope. The camera arm unit includes a proximal end and a distal end with a camera, and the proximal end of the camera arm unit is connected to the distal end of the apparatus body utilizing an adjustable rotary position linkage member. The communication unit is connected via a linkage device to the proximal end of the apparatus body, and the power source is housed by the apparatus body.

A light transmission optical member for endoscope includes an incident surface provided at a distal end portion of an insertion section, light being made incident on the incident surface as incident light from a proximal end side of the insertion section, and an emission surface for emitting the light as illumination light. The emission surface includes a diffusing section that diffuses the emitted light. The diffusing section includes a plurality of convex-shaped sections extending in a predetermined direction on the emission surface. Each of the convex-shaped sections includes a first slope section having a first angle with respect to the emission surface, and totally reflecting the incident light, and a second slope section having a second angle smaller than the first angle with respect to the emission surface, and transmitting and emitting reflected light totally reflected on the first slope section and the incident light.

The present disclosure relates to the field of endoscopy. Specifically, the present disclosure relates to delivery systems and methods for coagulating sites of bleeding within mucosal tissues, and in particular, for eradicating esophageal varices.

A tissue clip application fitting set or retrofitting set includes a cap attachment for placement on the distal head of a medical endoscope, which has a placement section and a tissue clip holding section. The cap attachment is notched at least at two angular positions forming at least two notches/slots/grooves. A working channel leads into the hollow chamber and exits the hollow chamber radially in a region distal to the placement section and proximal to the radially supported tissue clip. A first guiding or leading element is arranged after the working channel belonging to the retrofitting set, as seen in the distal direction. A corresponding second guiding or leading element is arranged within the hollow chamber at an angular distance from the first guiding or leading element so as to be oriented in extension to a working channel belonging to the endoscope.

Provided is an ultrasonic endoscope with which it is possible to improve a brush cleanability of a communication path. A distal end portion (44) of an ultrasonic endoscope (10) includes: a balloon attachment portion (152) for attachably and detachably attaching a balloon (60) to the distal end portion (44), the balloon attachment portion (152) including a first balloon groove (154) that is provided over an outer periphery of the distal end portion at least on a proximal end side of an ultrasound oscillator (92); and a communication path (90) for supply or suction of a fluid with respect to an inner space of the balloon (60). An entrance and exit way (91) of the communication path (90) is formed to be diagonally inclined with respect to a longitudinal axis of an insertion portion (12). The first balloon groove (154) includes a shallow groove portion (158) that is formed to have a groove depth smaller than other portions in a circumferential direction of the distal end portion (44), and the entrance and exit way (91) of the communication path (90) is provided in an internal region of the distal end portion (44) where the shallow groove portion (158) is formed.

An articulating cannula assembly is described. The articulating cannula assembly includes: a hand piece; a proximal housing situated above the hand piece; a cannula distally extending from the proximal housing, the cannula including an articulating segment; and a trigger that, when actuated, extends or contracts the articulating segment. The proximal housing can removably couple to the hand piece. The proximal housing can include an endoscope attachment structure for removably securing a proximal portion of an endoscope.

A needle and suture assembly is provided for use with an endoscopic suturing device with a needle holder arm. The needle assembly includes a needle tip and a needle body. The needle tip has a sharp end, a capture groove, a tab groove and a plug portion positioned between the capture groove and the tab groove. The needle body has first and second ends, tip tabs, retainers for removably retaining the needle body relative to the needle holder arm, and a suture opening. The needle tip is fixed relative to the needle body by plastic deformation of the tip tabs into the tab groove. A suture extends into the suture opening of the needle body and is fixed therein.
