An in vivo optical biopsy applicator of the vaginal wall for treatment planning, monitoring, and imaging guided therapy is described herein. The applicator may include an imaging probe operatively coupled to a laser ablation device. The applicator allows for non-invasive optical tissue monitoring in order to define pre- and post menopausal parameters, pre- and post-treatment microscopic changes, and offers an objective scientific tool in order to compare currently available medical, non-medicated, and energy-based treatment protocols.

The present invention provides an improved visual laryngeal mask comprising a snorkel, an end of the snorkel is provided with a fixing seat. The fixing seat is provided with an airbag, and the fixing seat has a recess which is provided with an airway opening. The inner wall of the snorkel longitudinally extends an imaging cavity and a cleaning channel. The imaging cavity has a built-in imaging device, and the imaging cavity and the cleaning channel protrude forward relative to the airway opening to form a stopper which prevents an epiglottis from blocking the imaging device.

An endoscope light source device includes: a box that is connectable to a light guide of an endoscope; a first light source configured to emit light of a first wavelength band; a second light source configured to emit light of a second wavelength band; a multiplexer configured to multiplex the light emitted by the first light source and the light emitted by the second light source; a diffuser configured to diffuse part of the light multiplexed by the multiplexer to an outside of an optical path for input to the light guide; a light quantity sensor configured to detect quantity of at least part of the light diffused by the diffuser; and an illumination controller configured to control quantity of light to be emitted from at least one of the first light source and the second light source.

For intraluminal ultrasound probes, the transducer is divided into multiple segments. The segments are connected in a way that allows them to slide relative to each other. This sliding arrangement allows for the transducer to be used in two different apertures at different times while in the patient. One aperture is shaped for insertion of the probe through a limited space, and the other aperture forms an array with a larger elevation extent, allowing greater quality imaging along the elevation dimension.

A seeker device for facilitating access to a desired location within an ear, nose, throat or other location in a body may include a proximal shaft, an elastic distal portion, and an atraumatic distal tip. The elastic distal portion has a default shape with at least one curve to facilitate advancement of a distal end of the elastic distal portion through various anatomical passageways, toward the desired location. In some embodiments, the seeker device may be paired with a dilator device, to perform a dilation procedure on an anatomical structure in the ear, nose, throat or other part of the body. In other embodiments, the seeker device may be paired with a flexible endoscope, to facilitate visualization of an anatomical structure or area.

Provided are an endoscope apparatus capable of reducing a diameter of a mounting portion in a case where a balloon is mounted on an insertion part of an endoscope, and the balloon. An endoscope apparatus includes an endoscope having an insertion part, and a balloon mounted on the insertion part. The balloon includes a first sleeve part, a second sleeve part, and a balloon main body. The balloon has an inner diameter of the first sleeve part, which is 1/10 or more and ½ or less of an outer diameter of the insertion part, in a pre-mounting state before the balloon is mounted to the insertion part. An inner diameter of the second sleeve part may be set to 1/10 or more and ½ or less of the outer diameter of the insertion part. Further, the inner diameter of the second sleeve part may be larger than ½ of the outer diameter of the insertion part and smaller than the outer diameter of the insertion part, and an axial length of the second sleeve part of the balloon may be set to be longer than that of the first sleeve part.

The present invention relates to the technical field of endoscopes, and discloses a confocal endoscope with a fixing device. The confocal endoscope includes an insertion tube, a flexible tube, a plurality of airbag assemblies, and a pressure supply assembly, where the flexible tube is slidably sleeved on the insertion tube, a plurality of containing units are formed in an outer wall of the flexible tube in an axial direction and are distributed in the axial direction of the flexible tube at intervals, each containing unit includes a plurality of containing grooves evenly distributed in a circumferential direction of the flexible tube, and the outer wall of the flexible tube is concaved inwards to form the containing grooves; the airbag assemblies and the containing units are arranged in a one-to-one correspondence mode, each airbag assembly includes a plurality of elastic airbags, the elastic airbags and the containing grooves are arranged in a one-to-one correspondence mode, and the elastic airbags are connected to inner walls of the containing grooves; the pressure supply assembly is selectively communicated with the elastic airbags of one or more airbag assemblies and configured to inject fluid media with certain pressure into the elastic airbags. According to the present invention, the insertion tube can be prevented from jittering.

An object is to provide a balloon mounting jig capable of reducing the burden of an operation of mounting a balloon in an insertion part of an endoscope. A balloon mounting jig (100) for mounting a balloon (60) including a first sleeve part (60A), a second sleeve part (60B), and a balloon main body (60C), to an insertion part (12) of an endoscope (10) or an insertion assisting tool, the balloon mounting jig (100) including: a main body (102) formed in a hollow cylindrical shape to be folded flat and having a first opening part (104) and a second opening part (106); a pair of guide pieces (108a, 108b) that face each other and are provided in the second opening part (106). A sliding surface (120) on which an outer peripheral surface of the insertion part (12) or the insertion assisting tool is slidable is provided on inner surfaces of the main body (102) and the pair of guide pieces (108a, 108b).

Apparatus and methods for deactivating bronchial nerves extending along the secondary bronchial branches of a mammalian subject to treat asthma and related conditions. An ultrasonic transducer (11) is inserted into the bronchus as, for example, by advancing the distal end of a catheter (10) bearing the transducer into the secondary bronchial section to be treated. The ultrasonic transducer emits circumferential ultrasound so as to heat tissues throughout circular impact volume (13) as, for example, at least about 1 cm.sup.3 encompassing the bronchus to a temperature sufficient to inactivate nerve conduction but insufficient to cause rapid ablation or necrosis of the tissues. The treatment can be performed without locating or focusing on individual bronchial nerves. The apparatus and methods utilized for lung tumor ablation.

Imaging apparatus, atherectomy devices, systems, and methods of operation thereof are disclosed. The imaging apparatus further comprises one or more light transmittable windows defined along the dividing layer and a catheter outlet port defined along a ventral side of the catheter body. The catheter outlet port allows the guidewire to advance out of the second catheter lumen and the catheter outlet port is aligned with at least one of the light transmittable windows such that the guidewire is within a field of view of the imaging component when the guidewire extends partially though the catheter outlet port. The atherectomy device can comprise a tubular housing and an inflatable balloon coupled to an exterior side of the tubular housing. The tubular housing includes a cutting window and a rotatable cutter configured to debulk the atherosclerotic material extending into the cutting window. The inflatable balloon can comprise a lumen in fluid communication with the housing lumen such that fluid introduced into the housing lumen via the catheter lumen inflates the inflatable balloon.
