Abstract
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.

A sealing assembly for use with an elongate device and an endoscope, the sealing assembly comprising:
- a body having a proximal end adapted for insertion of the elongate device, a distal end adapted for connection to an endoscope, and a lumen extending therethrough adapted to receive a shaft of the elongate device and to provide access to a working channel of the endoscope, the distal end configured for connection to various sizes of endoscopes;
- and
- a seal disposed in the lumen of the body, the seal having a passageway therethrough configured to sealingly engage the elongate device.
A holder for securing an elongate medical device relative to an endoscope, the holder comprising:
- a body having an attachment portion configured for attachment to the endoscope,
- a seal supported by the body, the seal having a passageway therethrough and one or more protrusion extending into the passageway such that the passageway sealingly receives the elongate medical device.
A system for holding an elongate medical device relative to an endoscope comprising:
- an endoscope having an access port;
- and
- a holder releasably affixed to the access port, the holder having a body with a cavity, and a sealing element disposed in the cavity, the sealing element having a passageway extending therethrough configured to sealingly receive the elongate medical device.
