Antimicrobial devices for use with medical devices and related assemblies and methods

An antimicrobial device for use in disinfecting at least a portion of a medical device, the antimicrobial device comprising:

• a monolithic, nonporous flexible housing formed from a flexible material, the flexible housing having a first open end forming an access port in the antimicrobial device to a cavity formed in the flexible housing for receiving the at least portion of the medical device within the antimicrobial device, a second closed end opposing the first open end, and a longitudinal axis extending between the first open end and the second closed end, the first open end being defined by a furthest longitudinal extent of the housing at a first longitudinal end of the housing, wherein the cavity in the flexible housing and an outer surface of the flexible housing are both tapered along the longitudinal axis of the flexible housing;
• an antimicrobial substance contained within the cavity in an amount sufficient to disinfect at least a portion of the medical device;
• a plurality of flexible concentric protrusions, at least one flexible protrusion of the plurality of flexible protrusions positioned at and directly adjacent to the first open end and extending around and into the cavity from an inner surface of the flexible housing in a direction perpendicular to the longitudinal axis of the flexible housing, wherein the at least one flexible protrusion is configured to directly engage with and secure the antimicrobial device to the at least a portion of the medical device in a manner allowing for the antimicrobial substance to make surface contact with the at least a portion of the medical device, wherein each successive concentric protrusion of the plurality of flexible concentric protrusions has a diameter that is less than a diameter of an adjacent concentric protrusion of the plurality of flexible concentric protrusions, wherein the at least one flexible protrusion and the flexible housing comprise a single unitary structure formed by injection molding;
• and
• a nonporous sealing member adhered to the first open end, the sealing member and the nonporous flexible housing configured to entirely contain the antimicrobial substance within the cavity, while only enabling the antimicrobial substance to pass through the access port at the first open end after the nonporous sealing member has been removed from the housing.
