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, a locking member coupled to the outer shell, an inner seal member, and a central opening that extends to the channel. The inner seal member may include a plurality of flaps.

Claims
