An endoscope including a handle and an insertion cord having a bending section body, a first steering wire portion, and a second steering wire portion. The bending section body includes segments and hinges keeping together, and formed integrally with, the segments, a center axis and a center plane traversing the center axis, the center plane dividing the bending section into a first bending section side and a second bending section side, and the segments including passages that together form a working channel lumen having a non-circular cross-section. Steering wire lumens are displaced with respect to the center plane towards the first side and configured to accommodate the first and second steering wire portions.

Endoscope comprising a bending section having displaced steering wire lumens

A medical device operable to obtain images of an internal cavity of a patient, including a handle; a flexible tube including a first section having a first radial cross-section area and a second section distal of the first section and having a second radial cross-section area smaller than the first radial cross-section area, the second section having an outer surface; a bending section extending from the flexible tube and including a proximal end segment, a distal end segment, and intermediate segments between the proximal end segment and the distal end segment, the intermediate segments hingedly connected to each other, the proximal end segment including a proximal end segment peripheral wall defining an internal space, wherein the second section is positioned at least partly in the internal space; and a camera assembly supported by the bending section and operable to generate images of distal views.

Articulated tip part for an endoscope

An endoscope tip part including an exterior housing including a circumferentially extending side wall with a proximal opening, the circumferentially extending side wall defining an interior space with an air volume; a camera assembly positioned in the interior space so that the air volume envelops at least the distal portion of the camera assembly; and an interior housing part including a circumferentially extending closure surface and a circumferentially extending attachment surface, the interior housing part being positioned in the proximal opening; wherein the exterior housing and interior housing part are formed as separate prefabricated components, wherein the closure surface is configured for closing the proximal opening of the exterior housing so as to liquid-seal the air volume in the tip part, and wherein the attachment surface extends proximally from the proximal opening and is configured for attaching the interior housing part to another element of the tip part.

Tip part for an endoscope

A videoscope with a tip part including a camera assembly having an image sensor and a first light source and a first tolerance compensator having a pre-compensation condition and a post-compensation condition, wherein movement from the pre-compensation condition to the post-compensation condition adjusts a distance along the optical axis of the first light source between the first light source and the image sensor, and wherein in the post-compensation condition the first tolerance compensator maintains the distance between the first light source and the image sensor at least along the optical axis of the first light source.

A medical device operable to obtain images of an internal cavity of a patient, including a handle; a flexible tube; a front end cap housing a camera assembly; a bending section extending from the flexible tube and including a proximal end segment and a distal end segment; a peripheral wall having an inner surface defining an internal space and including a cavity extending radially outwardly from the inner surface; a member having an outer surface and positioned at least partly in the internal space with the cavity overlapping the outer surface; and a protrusion of a hardened adhesive bonded to the outer surface of the member and extending into the cavity of the peripheral wall, wherein the member is one of, and the peripheral wall is comprised by another of, the flexible tube, the proximal end segment, the distal end segment, or the front end cap.

An endoscope having a tip part including an exterior housing including a circumferentially extending side wall with a proximal opening, the circumferentially extending side wall defining an interior space with an air volume; a camera assembly positioned in the interior space so that the air volume envelops at least the distal portion of the camera assembly; and an interior housing part including a circumferentially extending closure surface and a circumferentially extending attachment surface, the interior housing part being positioned in the proximal opening; wherein the exterior housing and interior housing part are formed as separate prefabricated components, wherein the closure surface is configured for closing the proximal opening of the exterior housing so as to liquid-seal the air volume in the tip part, and wherein the attachment surface extends proximally from the proximal opening and is configured for attaching the interior housing part to another element of the tip part.

An articulated tip part () for an endoscope (). The articulated tip part () comprises a distal end segment (), a proximal end segment () and a number of intermediate segments () arranged between the distal end segment () and the proximal end segment (). Each intermediate segment () comprises a first passage () adapted to accommodate and support an outer wall () of a tube () providing a working channel of the endoscope ().

A laryngeal mask () comprising an air-way tube () and a mask portion () with an inflatable cuff () which is arranged around the airway tube () at the distal end thereof. A gastric tube () which extends at least partially along the outer surface of the airway tube (), penetrates through the wall of said inflatable cuff () at a first location, extends through said inflatable cuff (), and ends in a connection to an opening () in the wall of the cuff at a second location at the tip part of the laryngeal mask, so as to provide a passage through said circumferential cuff. With respect to a central mirror symmetry plane said gastric tube extends along the outer surface of the airway tube () in an asymmetrical manner, through said inflatable cuff () at the first location arranged asymmetrically with respect to said central plane, through said inflatable cuff (), and ends in the connection to the wall of the cuff () at the second location at the tip part.

Laryngeal mask

A laryngeal mask for use in a patient includes an airway tube having an inner lumen and a distal end; and a mask portion connected at a proximal end thereof to the distal end of the airway tube and having a distal tip opposite the proximal end. The mask portion includes an inflatable cuff including an anterior cuff surface configured to contact the patient's tissue when the inflatable cuff is inflated; and a wedge portion including a stabilization surface and two walls connected to the inflatable cuff and extending therefrom toward the stabilization surface, the stabilization surface extending from the distal tip of the mask portion toward the distal end of the airway tube at a wedge angle of between about 12 and 30 degrees, the wedge angle formed between the stabilization surface and the anterior cuff surface when the inflatable mask is inflated, whereby the stabilization surface is transversely and longitudinally substantially flat to stabilize the laryngeal mask in use. The laryngeal mask has a gastric tube with a varying inner tube diameter.
