Devices and methods for treating rhinitis are provided. An integrated therapy and imaging device is provided for single handheld use. The device may have a hollow elongated cannula, a therapeutic element coupled to a distal portion of the cannula, an imaging assembly coupled to the cannula to provide visualization of the therapeutic element, and an articulating region operably coupled to the imaging assembly to articulate the imaging assembly. The imaging assembly may be articulated so as to translate vertically, laterally, axially, and/or rotationally.

An endoscope system includes an endoscope, and an insertion auxiliary tool into which the endoscope is inserted. A flexible portion of the insertion section of the endoscope includes, from a distal end side toward a proximal end side, a low flexural rigidity portion, a flexural rigidity varying portion in which a flexural rigidity increases from the distal end side toward the proximal end side, and a high flexural rigidity portion with flexural rigidity higher than that in the low flexural rigidity portion. When at least a part of the flexible portion projects from a distal end opening of the tube body, a position of the proximal end of the low flexural rigidity portion is positioned closer to a proximal end of the insertion auxiliary tool than the distal end opening of the tube body from the proximal end of the insertion auxiliary tool.

Devices and methods of use for an endoscopic accessory device that can be assembled and advanced over an endoscope positioned at a site within the body, the endoscopic accessory device including a body structure having seam structures on opposite sides of an elongate body structure, where the seam structures can be releasably joined to transform the body structure from a planar configuration to a tubular configuration.

An inspection analysis method includes an analysis step, a prediction step, and an output step. A processor analyzes inspection information related to an operation in an inspection and generates first operation data and second operation data indicating a content of the operation in the analysis step. The first operation data indicate a content of the operation in a first inspection. The second operation data indicate a content of the operation in a second inspection performed after the first inspection is completed. The processor compares the first operation data and the second operation data with each other and predicts a state of an inspection target in the prediction step. The processor outputs state information indicating the state to a reporting device in the output step.

Medical devices which are compatible with a camera for ventilating, intubating, and extubating a patient under continuous visualization. Methods for ventilating, intubating and extubating a patient with the medical devices.

A double-balloon catheter device for gastrointestinal anastomosis. The double-balloon catheter device for gastrointestinal anastomosis includes a liquid injection assembly, a double-balloon assembly, and a supporting device (15) connecting the liquid injection assembly and the double-balloon assembly. The liquid injection assembly includes a first balloon liquid injection connection port (2), a guide wire connection port (3), and a second balloon liquid injection connection port (4). The double-balloon assembly includes a double-balloon catheter device (5), and includes a first balloon (6) and a second balloon (7) that can expand-and that are respectively disposed on the two ends of the double-balloon catheter device (5). The double-balloon catheter device (5) is provided with a first balloon liquid injection channel (51), a guide wire channel (52), and a second balloon liquid injection channel (53).

Various embodiments disclosed relate to drug-coated balloon catheters for treating strictures in body lumens and methods of using the same. A drug-coated balloon catheter for delivering a therapeutic agent to a target site of a body lumen stricture includes an elongated balloon having a main diameter. The balloon catheter includes a coating layer overlying an exterior surface of the balloon. The coating layer includes one or more water-soluble additives and an initial drug load of a therapeutic agent.

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.

Provided is an ultrasonic endoscope with which it is possible to prevent damage to an imaging element even in a case where voltage from an external power supply is directly applied. A distal end portion main body (43) of an ultrasonic endoscope (10) is formed of a resin material, the distal end portion main body (43) includes an illumination system (53) that includes an illumination metal base (156), a first fixing member (170) that fixes the illumination metal base (156) to the distal end portion main body (43), a first insert hole (172) into which the first fixing member (170) is inserted, an observation system (55) that includes a lens barrel (160), a second fixing member (174) that fixes the lens barrel (160) to the distal end portion main body (43), a second insert hole (176) into which the second fixing member (174) is inserted, and an electrical connection member (178) that electrically connects the illumination metal base (156) and the lens barrel (160), and at least one of the illumination metal base (156), the lens barrel (160), or the electrical connection member (178) is connected to a ground.

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.
