Abstract

Connector assemblies, connector bodies, fluid systems including connector assemblies, and procedures for making fluid connections are disclosed.

First claim

1 . A connector assembly for making fluid connections comprising:
(a) a first hollow connector body, the first hollow connector body comprising a first resilient deformable seal having a central aperture and a lip surrounding the central aperture; a first locking mechanism integrally formed with the first hollow connector body, the first locking mechanism comprising at least one lug including a slot, and at least one ramp; a first hollow connector first body end and a first hollow connector second body end; (b) a second hollow connector body, the second hollow connector body comprising a second resilient deformable seal having a central aperture and a lip surrounding the central aperture; a second locking mechanism integrally formed with the second hollow connector body, the second locking mechanism comprising at least one lug including a slot, and at least one ramp; a second hollow connector first body end and a second hollow connector second body end;
(i) wherein the first hollow connector body and the second hollow connector body contact each other in a first position, and when subsequently twisted together, the first resilient deformable seal seals against the first hollow connector body, and the second resilient deformable seal seals against the second hollow connector body, in a second position, the second position comprising an actuation position.

2 . The connector assembly of claim 1 , further comprising a removable anti-actuation assembly comprising at least one peel strip, interposed between the first hollow connector first body end and the second hollow connector first body end, wherein, when the first hollow connector body and the second hollow connector body contact each other in the first position,
the anti-actuation assembly, when present, prevents forming the actuation position of the connector assembly, and when removed, allows forming the actuation position of the connector assembly.

3 . The connector assembly of claim 2 , wherein the anti-actuation assembly comprises a first surface facing the first hollow connector first body end and a second surface facing the second hollow connector first body end; and
the connector assembly further comprises an alignment arrangement for mating the anti-actuation assembly with the first connector hollow body and the second hollow connector body, the alignment arrangement comprising protrusions and recesses; wherein the first and second surfaces of the anti-actuation assembly, the first hollow connector first body end, and the second hollow connector first body end each have at least one protrusion and/or at least one recess, such that the first surface of the anti-actuation assembly mates with the first hollow connector first body end, and the second surface of the anti-actuation assembly mates with the second hollow connector first body end.

4 . The connector assembly of claim 2 , wherein the anti-actuation assembly comprises:
a first anti-actuation subassembly comprising the first surface of the anti-actuation assembly, and a first peel strip; and, a second anti-actuation subassembly comprising the second surface of the anti-actuation assembly, and a second peel strip.

5 . The connector assembly of claim 4 , wherein the first anti-actuation subassembly and the second anti-actuation subassembly are mated together when the first hollow connector body and the second hollow connector body contact each other in the first position.

6 . The connector assembly of claim 1 , wherein the first hollow connector body comprises a first connector external surface further comprising a first alignment indicator; and
the second hollow connector body comprises a second connector external surface further comprising a second alignment indicator; the first alignment indicator and the second alignment indicator aligning when the first hollow connector body and the second hollow connector body are in the actuation position.

7 . The connector assembly of claim 1 , comprising a genderless connector assembly.

8 . A connector body for use in a connector assembly for making fluid connections comprising:
a hollow connector body, the hollow connector body comprising a resilient deformable seal having a central aperture and a lip surrounding the central aperture; a locking mechanism integrally formed with the hollow connector body, the locking mechanism comprising at least one lug including a slot, and at least one ramp; a hollow connector first body end and a hollow connector second body end; and an anti-actuation assembly engagement portion comprising at least one recess and/or at least one protrusion; a removable anti-actuation assembly comprising at least one peel strip, and at least one recess and/or at least one protrusion, the at least one recess and/or at least one protrusion being engaged with the anti-actuation assembly engagement portion of the hollow connector body; and, a removable cap, engaged with the hollow connector body, wherein the removable anti-actuation assembly is interposed between the cap and the hollow connector first body end, the cap covering the hollow connector first body end.

9 . A process for making fluid connections comprising:
(a) placing a first hollow connector body, the first hollow connector body comprising a first resilient deformable seal having a central aperture and a lip surrounding the central aperture; a first locking mechanism integrally formed with the first hollow connector body, the first locking mechanism comprising at least one lug including a slot, and at least one ramp; a first hollow connector first body end and a first hollow connector second body end, in contact with a second hollow connector body, the second hollow connector body comprising a second resilient deformable seal having a central aperture and a lip surrounding the central aperture; a second locking mechanism integrally formed with the second hollow connector body, the second locking mechanism comprising at least one lug including a slot, and at least one ramp; a second hollow connector first body end and a second hollow connector second body end, in a first position; and (b) twisting the first hollow connector body and/or the second hollow connector body such that the first locking mechanism engages with the second locking mechanism, the first resilient deformable seal seals against the first hollow connector body, and the second resilient deformable seal seals against the second hollow connector body, in a second position, the second position comprising an actuation position.

10 . The process of claim 9 , further comprising removing an anti-actuation assembly comprising at least one peel strip, interposed between the first hollow connector first body end and the second hollow connector first body end, after (a) and before (b).

11 . A fluid system comprising a connector assembly of claim 1 , in fluid communication with a bioprocessing unit, the bioprocessing unit comprising a biocontainer having at least one wall including at least one port, an interior volume and including an impeller, wherein one of the first and second hollow connector bodies is in fluid communication with the port.

12 . The connector assembly of claim 3 , wherein the anti-actuation assembly comprises:
a first anti-actuation subassembly comprising the first surface of the anti-actuation assembly, and a first peel strip; and, a second anti-actuation subassembly comprising the second surface of the anti-actuation assembly, and a second peel strip.

13 . The connector assembly of claim 12 , wherein the first anti-actuation subassembly and the second anti-actuation subassembly are mated together when the first hollow connector
