Devices, systems, and methods for coupling tubing to a fluid reservoir to provide liquid to an endoscope system. A manifold for coupling to a fluid reservoir and a tubing assembly may include first portion interfacing with an interior of the fluid reservoir and a second portion configured to interface with tubing to be fluidly coupled to the interior of the reservoir. The first portion may include one or more openings to allow gas to pass into the fluid reservoir and liquid to pass out of the fluid reservoir. The second portion may include one or more ports for connecting to tubing that brings gas to the fluid reservoir and receives liquid from the fluid reservoir. The manifold may include a valve that selectively allows gas to pass into the fluid reservoir.

The present disclosure relates generally to medical imaging devices, such as a real-time visualization and diagnostic and/or therapeutic tool assembly, which may include an ergonomic handle and catheter configured for dual-function use during a medical procedure. By way of non-limiting example, the medical device may be configured for use with a probe, such as one disposed at the distal end of the catheter, and delivered within a bronchoscope working channel to provide real-time visualization (e.g., radial ultrasound imaging) and manipulation (e.g., diagnostic biopsy sampling) of pulmonary nodules in peripheral regions of the lung. As disclosed herein, in various embodiments, one or more components of the medical imaging device may be configured to position a catheter with a first tool/instrument (e.g., a biopsy needle) within a peripheral region of the lung while maintaining real-time visualization of the pulmonary nodule (e.g., with a second tool/instrument, such as a radial ultrasound probe).

A medical system including: a trocar configured to provide an artificial access to a body cavity of a patient; a medical instrument configured to be inserted through the trocar and into the body cavity of the patient for performing a medical function in the body cavity of the patient; and a controller configured to: determine whether the medical instrument is inserted into the trocar; and enable the performing of the medical function by the medical instrument only if the medical instrument is determined to be inserted into the trocar.

Several embodiments of the present invention are generally directed to medical visualization systems that comprise combinations of disposable and reusable components, such as catheters, functional handles, hubs, optical devices, etc. Other embodiments of the present invention are generally directed to features and aspects of an in-vivo visualization system that comprises an endoscope having a working channel through which a catheter having viewing capabilities is routed. the catheter may obtain viewing capabilities by being constructed as a vision catheter or by having a fiberscope or other viewing device selectively routed through one of its channels. The catheter is preferably of the steerable type so that the distal end of the catheter may be steered from its proximal end as it is advanced with the body. A suitable use for the in-vivo visualization system includes but is not limited to diagnosis and/or treatment of the duodenum, and particularly the biliary tree.

Methods and apparatus for accessing and treating regions of the body are disclosed herein. Using an endoscopic device having an automatically controllable proximal portion and a selectively steerable distal portion, the device generally may be advanced into the body through an opening. The distal portion is selectively steered to assume a selected curve along a desired path within the body which avoids contact with tissue while the proximal portion is automatically controlled to assume the selected curve of the distal portion. The endoscopic device can then be used for accessing various regions of the body which are typically difficult to access and treat through conventional surgical techniques because the device is unconstrained by straight-line requirements. Various applications can include accessing regions of the brain, thoracic cavity, including regions within the heart, peritoneal cavity, etc., which are difficult to reach using conventional surgical procedures.

An imaging component comprises shaft and a cavity extending across the shaft from its proximal end towards its distal end. The cavity removably receives at least one of a plurality of different instruments. A wall of the cavity comprises an elongated opening in communication with an exterior of the shaft at least partially along the shaft. An imaging transducer is coupled to the distal end of the shaft. The imaging component is advanced to a target site either alone or with a first instrument coupled thereto. A therapeutic or diagnostic procedure is performed with the first instrument. The first instrument is then retracted and removed from the imaging component while the imaging component stays at the target site. A second instrument is then coupled to the imaging component and advanced to the target site to perform a further therapeutic or diagnostic procedure.

A program causes a computer communicatively connected to an endoscope apparatus provided with a master endoscope and a slave endoscope to execute processing, including acquiring a master endoscope image of a subject from the master endoscope, acquiring a slave endoscope image of the subject from the slave endoscope, and correcting a color tone of at least either one endoscope image of the master endoscope image and the slave endoscope image so as to reduce a difference in color tone between the master endoscope image and the slave endoscope image that have been acquired.

A system is disclosed that can have a first device and a second device. The first device can have a tube, a deflectable section, and a camera. The second device can have a first tube. A stabilizer can be advanceable from the first tube. The second device can have a second tube. A third tube can be advanceable from the second tube. The first device can be an endoscope. The first device can be attachable to the second device via a connector.

A method for removing one or more objects or materials from a body lumen includes delivering a tube and an expandable device to the body lumen to a position proximal to the one or more objects or materials. The expandable device is positioned with a lumen of the tube, and the expandable device includes a lumen extending from a distal portion to a proximal portion. The method further includes proximally retracting the tube such that the expandable device remains in the position proximal to the one or more objects or materials, distally advancing the expandable device such that the distal portion of the expandable device at least partially surrounds the one or more objects or materials, at least partially closing a distal end of the expandable device, and moving the expandable device proximally to remove the expandable device and the one or more objects or materials from the lumen.

Multi-stage catheter device configured to navigate through complex narrow tissue openings such as lung bronchi pathway openings of 3 millimeters or less. The device comprises a proximal catheter portion containing a hollow torque shaft, with a distal catheter portion connected to the proximal portion by a rotatable coupler connected to this hollow shaft. The distal position of the proximal catheter can be controlled by up to four independently controlled proximal stage steering cables positioned outside of the shaft, and the shaft itself can be used to rotate the distal catheter about the rotatable coupler. The position of the distal end of the distal catheter can be further controlled by up to four independently controlled distal stage steering cables positioned inside of the hollow shaft. The device is tipped by a tool plate, which can be equipped with various sensors and other instruments, connected to the outside via other conduits.
