An endoscope accessory, such as a coupler device, is provided that includes a main body with a visualization section for allowing viewing of tissue by the endoscope and a proximal end configured for attachment to a distal end portion of the endoscope. The device includes a passage within the main body having an exit portal and a proximal end aligned with the working channel of the endoscope. An instrument passing through the passage is capable of angular adjustment relative to the main body of the coupler device by actuation of the endoscope.

Provided is a scope that can comprise a tubular casing, a proximal end, a distal end, an internal volume, a longitudinal axis of extension extending from the distal end to the proximal end, a vertical axis extending perpendicularly to the longitudinal axis of extension and one or more apertures along a length L of the longitudinal axis of extension; a handle having a proximal end and a distal end; and image capture devices each located within the internal volume of the tubular casing.

Integrated hysteroscopic treatment systems which includes an endoscopic viewing system, a fluid management system, a resecting device and a controller for operating all the systems.

A distal end unit for endoscope is provided in a distal end portion of an insertion portion and includes: an electronic module including an optical system and an electrode; a substrate including a connection portion electrically connected to the electrode of the electronic module, and including a connection land on which an electronic component is mounted; a holding member holding the electronic module and the substrate connected to the electrode; and a distal end frame body made of resin, on which the electronic module, the substrate and the holding member are integrally mounted via insert molding by loading the holding member holding the electronic module and the substrate in a mold such that an entrance surface of the optical system is exposed at an outer surface of the distal end frame body and the connection portion extends to a proximal end side.

A multi-focal, multi-camera endoscope having a tip section including a first optical assembly for generating a first image of a body cavity; a second optical assembly for generating a second image of a body cavity; at least one illuminator associated with each of the first optical assembly and second optical assembly; and a processing system configured to: zoom the first optical assembly and thereby generate a zoomed first image in place of the first image; and automatically cause a physical display to eliminate a display of the second image and to only display said zoomed first image. To eliminate the display of the second image, the processing system reduces a power supply to the second optical assembly, reduces an illumination intensity of an illuminator associated with the second optical assembly or causes the physical display to power off, darken, or blacken.

An instrument insertion assisting tool includes a wire attaching member, a guide piece, and a first engaging member. The wire attaching member is configured to be attached to a manipulator of an endoscope at a position adjacent to a forceps plug and offset from a seal hole of the forceps plug. The forceps plug is attached to a forceps port of the manipulator and has the seal hole through which a wire is inserted. The guide piece projects from the wire attaching member. The guide piece is configured to direct the wire so that a first portion of the wire is directed along a central axis of the seal hole. The first engaging member projects from the wire attaching member. The first engaging member is configured to direct the wire so that a second portion of the wire is directed along the wire attaching member.

Apparatuses and methods for imaging objects in cardiovascular system are described. In one embodiment, an apparatus includes a catheter configured to traverse a blood vessel. The catheter includes: a flushing fluid inlet configured to inject a flushing fluid into the blood vessel; a flushing fluid outlet configured to evacuate the flushing fluid from the blood vessel; and an imaging module configured to image an object in the blood vessel. A first volumetric flow of the flushing fluid into the blood vessel and a second volumetric flow of the flushing fluid out of the blood vessel are synchronized to maintain a pressure in the blood vessel below a predetermined threshold.

An endoscope apparatus can include distal end portion; a raising base accommodation portion; an insertion channel; a camera; a raising base; a guide wire abutting portion; a first guide portion; and a second guide portion, and relative to edges of an image on a monitor, the first guide portion guides the guide wire to a first position such that the guide wire appears in the image with the guide wire intersecting a first edge, and the second guide portion guides the guide wire to a second position such that the guide wire appears in the image with the guide wire intersecting a second edge.

A diagnostic imaging catheter includes a sheath configured to be inserted into a living body; a drive shaft rotatable in the sheath; and an imaging core portion attached to the drive shaft in the sheath. The imaging core portion includes a transmission and reception member capable of transmitting and receiving a signal; and a housing holding the transmission and reception member. A side surface of the housing that faces a radial direction of the sheath includes an inclined portion that is inclined, up to a distal end of the housing, to approach a central axis line of the drive shaft from a proximal side to a distal side of the inclined portion. The inclined portion extends from a proximal side of a distal end of the transmission and reception member to a distal side of the distal end of the transmission and reception member.

A radial illumination system is for projecting a light pattern radially. A light source generates a light output to an optical fiber. A ferrule is provided around the end of the optical fiber, and a reflector is mounted over or in the ferrule or integral with the ferrule, for redirecting the light to form generally radial light. In this way, a simple design with low component count is able to perform the optical alignment and optical reflecting functions.
