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.
