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.

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 instruments. In particular, the present disclosure relates to a biopsy cap and endoscope biopsy cap housing with improved stability and stress distribution to securely and removably attach to an endoscope biopsy port. In one example, a biopsy cap housing may include a first center-split half comprising a first half of an upper and lower chamber and first pivot member, and a second center-split half comprising a second half of an upper and lower chamber, and second pivot member, wherein mating surfaces of the first and second center-split halves may be configured to interlock to define the upper and lower chambers.

Abstract: The disclosure relates generally to the field of medical devices for accessing body lumens. In an embodiment, a catheter may comprise a shaft comprising a proximal end, a distal end, an actuating portion proximal to the distal end, and a first lumen extending along a length of the shaft between the proximal and distal ends. A plurality of slots may be disposed and spaced-apart from each other along the actuating portion. The plurality of slots may extend radially into the first lumen.

Abstract: An adapter for allowing a cap assembly to fit securely on two or more medical device ports with different sizes, shapes, and/or dimensions. The cap assembly has a housing with an interior configuration corresponding with an exterior configuration of a first port and surrounding port region of a medical device. An adapter having an exterior configuration corresponding with the housing interior configuration, and an interior configuration corresponding with the second port and port region may be fitted within the housing. Alternatively, an adapter having a first configuration may be provided in the housing to configure the housing interior to correspond with the exterior configuration of the first port. The adapter may be shiftable into a second configuration with an interior corresponding with the exterior configuration of the second port. The first and second configurations of the housing interiors adapt the housing to fit securely on the corresponding port.
