A combined ultrasonic and endoscopy system includes a cannula with a distal tip configured for insertion into an internal organ or other internal body structure. The distal tip is configured to include both an ultrasound probe head and a camera module. The ultrasonic and direct vision endoscopy images can be simultaneously displayed to a user on a display monitor. The ultrasound probe head can be rotated and steered to scan any location in the human organ cavity. The ultrasound probe can be re-usable or single use. The endoscopy system can be configured with a handheld portion that includes a re-usable handle portion and a single use portion that is configured to be disposed of following a single use. The system can also be configured using a conventional re-usable endoscope with working channels and an endoscopy processing tower system.

Devices, systems, and methods for delivering various implantable devices, such as heart valve implants, with the use of a steerable imaging element are described. An imaging element is positioned adjacent the implantable device and implant site, a relationship between the implantable device and the implant site is visualized and/or imaged, and the implantable device is anchored and/or adjusted with reference to the visualization and/or imaging thereof.

An endoscope is provided to examine internal organs with front and rear views. The endoscope comprises a shaft extending from a distal end in a rearward direction along a longitudinal axis towards a proximal end, with the distal and proximal ends defining a hollow channel extended there-through. The endoscope further comprises a first lens positioned adjacent to the distal end and configured to receive a first image in a forward direction along the longitudinal axis, with the forward direction generally 180 degree from the rearward direction. The endoscope further comprises a rearview module positioned adjacent to the distal end. The rearview module comprises a second lens configured to be positioned adjacent to the distal end, and receive a second image in a target direction having a directional component in the rearward direction along the longitudinal axis, independently of the first lens receiving the first image in the forward direction.

An improved bi-directional steerable catheter is provided. The catheter generally comprises a catheter body, tip section and control handle. The catheter further comprises first and second puller wires extending from the control handle, through the catheter body and into the tip section. The control handle has deflection means for each puller wire that include a gear, and a carrier to which the proximal end of a puller wire is anchored. The gear is rotatably coupled to a lever controlled by an operator and the gear engages the carrier such that rotation of the gear by the lever results in longitudinal movement of the carrier, which results in deflection of the tip section.

An imaging module includes: an electrical cable; an imaging device; and a flexible wiring board with wirings electrically connecting the imaging device with the electrical cable. The flexible wiring board includes: a device mounting portion on which the imaging device is mounted, and one end of the device mounting portion in a longitudinal direction has a bent portion; and a rear portion that bends and extends from the bent portion to a side opposite the imaging device. The device mounting portion has a mounting surface intersecting an axial direction of a distal end of the electrical cable, and the imaging device is mounted on the mounting surface, and the wirings extend from the mounting surface, pass through the bent portion, and connect with the electrical cable at the rear portion.

An endoscope system includes a mother endoscope, a baby endoscope and a fixing member. The mother endoscope includes a first insertion section, a first operation section, a treatment instrument insertion channel and an opening. The baby endoscope includes a second insertion section and a second operation section. The first operation section includes a projection portion. The second operation section includes a recess portion that is a recessed face formed such that at least part of the recessed face comes into face contact with a surface of the projection portion. The second operation section is fixed to the first operation section in a state where the recess portion is in contact with the surface of the projection portion.

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.

Provided is an endoscope capable of effectively suppressing breakage of a channel while sufficiently exhibiting performance of a plurality of portions having different degrees of bending. The endoscope includes an insertion portion and a channel arranged inside the insertion portion. The insertion portion includes a bending section that is bendable based on an operation, and a flexible tube portion that is bendable by an external force unrelated to the operation. The channel includes an inner layer and an outer layer formed outside the inner layer, the inner layer is made of polytetrafluoroethylene having a solid structure, and the outer layer is made of polytetrafluoroethylene having a porous structure.
