Abstract
The present disclosure relates generally to the field of medical devices such as endoscopes, endoscope assemblies, guide tubes, introducers, and instrument caps for endoscopes, guide tubes, and introducers. In particular, the present disclosure relates to biopsy cap configurations providing scalable access for medical instruments to a working channel, such as a working channel for an endoscope.
Claims20
A seal assembly, comprising:
- a biopsy cap having a first end and a second end, an inner chamber defined therein between the first end and the second end, and a cap aperture at the first end in fluid communication with the inner chamber;
- a plurality of seal members disposed within the inner chamber, each seal member of the plurality of seal members having a seal aperture in fluid communication with the cap aperture;
- and
- a base frictionally secured to the inner chamber, the base having a base aperture therethrough in fluid communication with each of the seal apertures, a securement region configured to engage a port of an endoscope, and an extension extending distally beyond the securement region;
- wherein:
- the plurality of seal members are disposed between the base and the first end of the biopsy cap;
- the biopsy cap and the base are configured to be frictionally secured together;
- and
- the extension extends along a limited extent around the circumference of the base and is configured to assist the user as a handle for the user to remove the base from the port.
A device configured to attach to a port of an endoscope, the device comprising:
- a biopsy cap;
- and
- a base defining an aperture therethrough in fluid communication with a port of an endoscope, and having a securement region configured to engage the port and an extension extending distally beyond the securement region and circumferentially along a limited extent of the circumference of the base;
- wherein:
- the base engages the top surface of the port;
- the base is configured to engage the distal end of the biopsy cap to retain the base frictionally with respect to the biopsy cap;
- and
- the extension is configured to assist the user as a handle for the user to remove the base from the port.
A seal system, comprising:
- an endoscope having a working channel and a port at a proximal end of the working channel;
- a base having a base aperture therethrough, a securement region configured to engage the port, and an extension extending distally beyond the securement region and circumferentially along a limited extent of the circumference of the base;
- and
- a biopsy cap having a first end with a cap aperture therethrough in fluid communication with the base aperture and the port, a second end, and an inner chamber defined therein between the first end and the second end and in which the base is disposed;
- wherein:
- the base is frictionally secured to the second end of the biopsy cap to be secured thereto, and the extension extends distally from the base and beyond the securement region and the second end of the biopsy cap, and is configured to assist the user as a handle for the user to remove the base from the port.
