Abstract: Biopsy caps and seals, and methods for making and using the same may be provided in conjunction with an endoscope assembly. A seal may include a main body including a circumferential outer wall surrounding a central lumen. The seal may include at least one support wall extending radially from the outer wall towards a center of the lumen, and at least one helical flap extending from the support wall helically downward along an inner surface of the outer wall, where the at least one helical flap defines an opening at the center of the lumen. The seal may alternatively include a plurality of projections extending radially inward from the outer wall towards a center of the lumen, where the plurality of projections are arranged in a series of circumferentially and angularly offset layers.

Abstract: The present disclosure relates generally to the field of medical devices. In particular, the present disclosure relates to valve configurations providing sealable access for medical instruments to a working channel, such as a working channel for an endoscope.

Abstract: The present disclosure relates generally to the field of medical instruments. More particularly, the present disclosure pertains to medical instruments for use with an endoscope, such as a biopsy cap and a biopsy cap housing with improved stability and stress distribution, for example, to securely attach to an endoscope biopsy port.

Abstract: Endoscope assemblies, biopsy caps, and methods for making and using the same. An example endoscope assembly may include an endoscope having a channel formed therein and a port that provides access to the channel. A cap may be coupled to the port. The cap may include a base having a securing member for securing the cap to the port, an outer shell and a brush section disposed within the interior volume adjacent the disk shutter section, the brush section including a plurality of brushes arranged in a helical fashion.
