A seal is provided for effectively inhibiting the egress of fluids from the working channel of an endoscope when an elongate device having a region with a non-circular cross-sectional shape is disposed therein. The seal has a body portion with a proximal end adapted for insertion of the elongate device, a distal end adapted for connection to the proximal end of the endoscope, and a wall defining a lumen adapted to receive the elongate device and to provide access to the working channel of the endoscope. The seal includes a sealing element for sealing the region of the elongate device with a non-circular cross-sectional shape. The sealing element conforms to the profile of the non-circular region.

Fluid seal for endoscope

Locking device that is mounted on an endoscope or the like for selectively securing the position of a guide wire and/or catheter relative to the endoscope or the like. The locking device preferably includes a side wall with an opening therein for receiving the proximal end of a guide wire or catheter. The opening is preferably J-shaped or boot shaped, and has an entry end and a locking end. Once a guide wire or catheter is in a desired position within a body cavity, the portion of the guide wire or catheter that extends outside of the endoscope or the like may be moved into the opening. More particularly, a portion of the guide wire or catheter may be inserted by an operator through the entry end of the opening and into the locking end, wherein the locking end frictionally secures the position of the guide wire or catheter relative to the endoscope or the like.

Guidewire and catheter locking device and method

Connector for use with a medical catheter assembly and medical catheter assembly including the connector. In one embodiment, the connector comprises a rear portion, an intermediate portion, and a front portion. The rear portion is frusto-conical in shape and tapers rearwardly in cross-sectional diameter from its front end. A centrally-disposed, smaller-diameter, longitudinal bore is provided in the rear portion, the bore being appropriately dimensioned to receive a guidewire therethrough. The intermediate portion is generally cylindrical and is shaped to include a centrally-disposed, larger-diameter longitudinal bore and a pair of longitudinally-extending slots providing access to the larger-diameter bore. The front portion is frusto-conical in shape and tapers forwardly in cross-sectional diameter from its rear end. In use, a silicone tube is inserted into the larger-diameter bore of the intermediate portion, and the rear and intermediate portions of the connector are inserted into a gastrostomy feeding tube. A silicone glue is then used to bond the silicone tube to the gastrostomy feeding tube. The front end of the connector is inserted into a dilator and is secured thereto by spin-welding.

An endoscope seal that effectively inhibits the egress of fluids from the working channel of an endoscope when an elongate device having a non-circular shaft is disposed therein. The endoscope seal includes a body portion having a proximal end adapted for insertion of an elongate device such as a rapid exchange biliary catheter, a distal end adapted for connection to the proximal end of an endoscope, a lumen extending therethrough which is adapted to receive the elongate device and to provide access to the working channel of the endoscope, and a means for conforming to the non-circular shaft of the elongate device to inhibit the flow of fluid from the working channel of the endoscope. The conforming means may, for example, comprise one or more protrusions extending radially inward in the lumen of the body portion, a sealing material such as a surgical foam that is disposed in the lumen of the body portion, or a sealing mandrel. Whether a single protrusion, a plurality of protrusions, a sealing material or a sealing mandrel is utilized, the present invention provides endoscope seals that readily seal about elongate devices having either circular or non-circular profiles.
