Abstract

An enteral connector assembly and system (700) communicates fluid between a bag B′ or a bottle B″ and an enteral feeding set. The system (700) includes an end cap (705) that communicates enteral fluid across a barrier (715) having a specially configured barrier keyway (720) formed with a barrier port (725). The barrier (715) establishes an interstice (165) that when combined with the spike barrier (715) prevents introduction of and fluid communication with legal intravenous spikes (LS) and other incompatible connectors, while enabling connection to and fluid communication with compatible components such as an interconnect (740) having multiple tines (745) that include specially shaped tips (750) that extend across the interstice (165) to pierce a seal, septum, and/or sealing membrane and form a fluid pathway.
