<p>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 adapte d to receive the elongate device and to provide access to the working channel of the endoscope, and a means for conforming to the n on- circular shaft of the elongate device to inhibit the flow of fluid from the working channel of the endoscope. The conforming mean s may, for example, comprise one or more protrusions extending radially inward in the lumen of the body portion, a sealing materi al 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.</p> |
