An endoscopic instrument includes a heat-generating component that is thermally coupled to a heat sink via a movable contact structure. The movable contact structure accommodates the relative motion between the thermal conduit and heat sink to maintain the thermal coupling between those elements, and prevent damage to such thermal coupling when the instrument is exposed to elevated temperatures, such as during autoclaving.

An articulated bending section body has a number of segments including a proximal end segment, a distal end segment and a number of intermediate segments. Each intermediate segment has a central passage adapted in cross-sectional shape to receive and support the exterior surface of a bendable tubular member providing a working channel of the endoscope. The cross-sectional shape includes a number of sectors of a circular periphery having a shared center and the same radius, the total length of the sectors being longer than half of the circular periphery. The cross-sectional shape comprises at least one outwardly extending lobe. The exterior surface of the bendable tubular member providing the working channel of the endoscope forms a closed lumen adjacent but separated from the working channel of the endoscope.

A handle (2) for an endoscope (1), the handle (2) having a proximal end, a distal end, a front and a back, and the handle (2) including a gripping section (12) separated by a transition section (17) from an operation section (13). The gipping section (12) surface is provided with grooves. The gripping section has a cross-section with mirror symmetry and varying radius of curvature, with the minimum radius (r) of curvature at the front of the handle (2).

Systems, methods and devices for performing an endoscopic procedure are provided herein, including an endoscopic plug designed to create a sealed environment within a body cavity using an internal expandable portion which maintains a collapsed configuration during an insertion process or removal process, but which can be expanded upon insertion into the body cavity to secure an internal portion of the endoscopic plug within the body cavity while creating a seal to prevent leakage of gas or fluid out of the body cavity during the endoscopic procedure.

An articulated medical device having a hollow core, capable of large degrees of maneuverability through small spaces of a patient to reach a target with minimal invasiveness, and once the medical device has reached the target, allowing a medical tool to be guided through the hollow chamber for facilitating medical procedures, including endoscopes, cameras, and catheters, at the target.

An insertion device includes: a tube having a channel hole and a communication hole; a frame member having a tube insertion hole and a forceps channel and disposed to cover a periphery of the communication hole; and a closing member configured to close the channel hole in the tube at a position closer to a proximal end side than the communication hole and having a distal end surface disposed to face the communication hole.

Aspects of the present invention relate to a method for locating an expandable implant for treating BPH within the prostatic urethra of a patient. The delivery device comprises an inner tube and an outer sleeve moveable relative to the inner tube between a stored position and a deployed position. The outer sleeve surrounds the inner tube to define an annulus therebetween and the expandable implant is retained within the annulus when the outer sleeve is in the stored position.
