Claims20
A seal assembly, comprising:
- a biopsy cap having an inner chamber therein, a cap aperture at a first end in fluid communication with the inner chamber, and a securing member at a second end;
- a plurality of seal members disposed within the inner chamber, each seal member having a seal aperture in fluid communication with the cap aperture;
- and
- a base disposed within the securing member, the base having a base aperture therethrough in fluid communication with each of the seal apertures.
1 more element
A device configured to attach to a port of an endoscope, comprising:
- an aperture through the device in fluid communication with the port;
- at least two extensions that extend distally from the base and are configured to engage a port of a working channel;
- and
- a recess disposed about the device configured to engage a biopsy cap.
1 more element
A seal system, comprising:
- an endoscope having a working channel and a port at a proximal end of the working channel;
- a base disposed about the port, the base having a base aperture therethrough;
- and
- a biopsy cap having a cap aperture therethrough, and a securing member at an end of the biopsy cap, the securing member disposed about the base such that the cap aperture is in fluid communication with the base aperture and the port.
