Abstract: A ureteroscope system includes a handle; an elongated shaft extends from the handle to a distal end and includes a working channel which is opened at the distal end; an external member extends from a proximal end to a distal end and is coupled to the shaft, the member includes a hub and a tube defining a first external channel; and a coupling mechanism defines first and second tubes and is coupled the distal end of the member to the distal end of the shaft. The first tube defines a first lumen and the second tube defines a second lumen which is sized and shaped to receive a distal end of the member. A proximal portion of the first tube is sized and shaped to be inserted into a distal portion of the shaft such that the first lumen is opened to the working channel.

Abstract: 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.

Abstract: In one embodiment, an apparatus includes a support portion disposable within a pelvic region and a strap extending from the support portion. The strap has a length and is configured to be disposed at least partially within a pelvic tissue. A sleeve is releasably disposed over at least a portion of the strap. The sleeve has a length that is longer than the length of the strap. In some embodiments, the length of the sleeve is at least twice as long as the length of the strap. In some embodiments, a suture couples the sleeve to the strap. The apparatus can also include a suture disposed at least partially within an interior of the sleeve and forming two strands of suture within the interior of the sleeve. The two strands are separated by a distance defined by a separator portion of the sleeve.
