  • Patent number: 11173635
    Abstract: Fluid transfer assemblies for transferring fluid into or out of a single vessel and distributing the fluid to multiple other vessels are provided. The fluid transfer assemblies are customizable, substantially aseptic, and single-use. The fluid transfer assemblies may be manufactured by solidifying polymeric materials to form a body around a mandrel with protrusions engaged to fluid conduits and leaving recesses in the solidified polymeric material to stretch the resultant body and remove the mandrel with protrusions. The resultant fluid transfer assembly may be surrounded by a rigid housing and valves may be engaged with the conduits and/or body to control the fluid flow within the fluid transfer assembly.
