Embodiments of a sizing device that can be used to measure the size of airways lumens, such as those connected to lungs. The sizing device can have different expandable elements in order to accurately and consistently measure the particular dimensions of a lumen. In some embodiments, markings viewable by a user can be used to determine the particular size.

According to the present invention, there is provided an endoscopy system comprising an endoscope guide and an endoscope. The endoscope of the system comprises a proximal end and a distal end. The endoscope guide of the system comprises a proximal end, a mid-section comprising at least one endoscope entry port, a distal end comprising at least one endoscope exit port, a lumen capable of receiving an endoscope extending from the at least one entry port to the at least one exit port and at least one bend located between the at least one entry port and the at least one exit port. The endoscope guide is capable of directing the insertion of the distal end of the endoscope into a body cavity when the distal end of the endoscope exits the endoscope exit port and the distal end of the endoscope guide is also configured so as to be capable to be retained within the body cavity during a surgical procedure so as to control the positioning of the distal end of the endoscope within the body cavity.

The present disclosure relates to the field of body lumen drainage. Specifically, the present disclosure relates to implantable medical devices for facilitating the flow of fluids and materials between adjacent body lumens. In particular, the present disclosure relates to a drainage stent which maintains an open flow passage between fused tissue layers.

A treatment device includes a flexible sheath; a wire configured to be inserted into the sheath; a first treatment member disposed at distal side from the wire; a second treatment member disposed at a distal side from the first treatment member; and a protection member configured to cover the second treatment member when the first treatment member projects from a distal end of the sheath.

Embodiments generally relate to propulsion devices, systems, or components thereof, for progressing instruments along passages, as well as associated methods of manufacture. For example, the instruments may include tools, sensors, probes and/or monitoring equipment for medical use (such as endoscopy) or industrial use (such as mining). The described embodiments may also be suitable for applications in other fields to progress an instrument along a passage. Some embodiments relate to an endoscope comprising or configured to receive a propulsion tube configured to assist in progressing the endoscope along a passage.

Disclosed embodiments include apparatuses, systems, and methods for providing a sheath tip with an angled distal face to conform the sheath to a surface of tissue toward which the sheath is being extended to potentially help reduce or avoid tissue damage upon extending a sheath to convey an elongated instrument for sampling or treatment. In an illustrative embodiment, an apparatus includes a sheath tip positionable at an end of a sheath configured to convey an elongated medical instrument to a location adjacent a detection range of a detecting device. The sheath tip includes a distal member that extends a finite distance beyond the end of the sheath. The distal member is detectable by the detecting device when the end of the sheath is within the finite distance of the detection range of the detecting device.

A deflectable endoscope including an imaging structure, an outer member having a proximal portion and a distal portion, an elongated column member extending distally from the outer member and an inner member positioned coaxial with the outer member and attached to the column member. The inner member extends distally of the outer member and has a distal tip portion. A reinforcement member is positioned over the column member to restrict axial movement of the column member such that when one of the inner member or outer member is moved with respect to the other, axial compression of the column member is restricted by the reinforcement member causing the distal tip portion of the inner member to deflect laterally.

An apparatus for controlling positioning of wires and/or tubing that extends from a handle of a medical device. An exemplary apparatus includes a device attachment mechanism configured to removably attach to a handle of a medical device and a guide component configured to maintain a plurality of different positions relative to the device attachment mechanism and the handle of the medical device. The guide component allows a user to alter the direction (i.e., biases) any wires or tubing, such as electrical wires or saline tubes that extend from the handle to other instrumentation, such as pumps or generators.
