Bioreactor connectors
Aspects of the disclosure relate to rotating bioreactors and articles and methods that are useful for adapting a rotating bioreactor for use with tissues or scaffolds of different sizes. In some embodiments, bioreactors comprising a reservoir and an arbor assembly are provided herein, in which the arbor assembly comprises a rotatable support to which a tissue or tissue scaffold can be attached.
1. A bioreactor arbor assembly comprising:
a first cylindrical end and a second cylindrical end, wherein the first and second ends confront one another and are connected via an elongate member, wherein the elongate member is a shaft;
a first cannula unit connected to the first end;
a second cannula unit connected to the second end; and
a spacer unit, the spacer unit positioned between the first cannula unit and the first cylindrical end.
2. The bioreactor arbor assembly of claim 1 , wherein the first and second cannula units are connected via threaded screws onto the first and second ends.
3. The bioreactor arbor assembly of claim 2 , further comprising a tubular scaffold wherein a first opening of the tubular scaffold is attached to the first cannula unit and a second opening of the tubular scaffold is attached to the second cannula unit.
4. The bioreactor arbor assembly of claim 3 , wherein the first cannula unit comprises an orifice and the second cannula unit comprises an orifice, wherein the first and second cannula units are arranged such that they confront one another along a longitudinal axis that passes through the two orifices.
5. The bioreactor arbor assembly of claim 1 , wherein the first cannula unit comprises an orifice and the second cannula unit comprises an orifice, wherein the first and second cannula units are arranged such that they confront one another along a longitudinal axis that passes through the two orifices.
6. A bioreactor, comprising:
a reservoir that comprises a body, the body defining a central cavity and a seal wash inlet, a seal wash outlet, a reservoir inlet and a reservoir outlet, the seal wash inlet, the seal wash outlet, the reservoir inlet, and the reservoir outlet each extending through the body; and
an arbor assembly releasably receivable in the reservoir, the arbor assembly comprising:
an elongate member;
a first cylindrical end and a second cylindrical end, wherein the first cylindrical end and second cylindrical end confront one another and are connected via the elongate member;
a first cannula unit connected to the first end;
a second cannula unit connected to the second end; and
a spacer unit, the spacer unit positioned between the first cannula unit and the first cylindrical end.
7. The bioreactor of claim 6 wherein the reservoir further comprises:
a drive shaft extending from a location outside the body and projects into releasable contact with the arbor assembly.
8. The bioreactor of claim 6 wherein the first and second cannula units of the arbor assembly are connected via threaded screws onto the first and second ends.
9. The bioreactor of claim 6 wherein the arbor assembly further comprises a tubular scaffold wherein a first opening of the tubular scaffold is attached to the first cannula unit and a second opening of the tubular scaffold is attached to the second cannula unit.
10. The bioreactor of claim 9 wherein the first and second cannula units of the arbor assembly are connected via threaded screws into the first and second end.
11. The bioreactor of claim 10 wherein the first cannula unit of the arbor assembly comprises an orifice and the second cannula unit of the arbor assembly comprises an orifice, wherein the first and second cannula units are arranged such that they confront one another along a longitudinal axis that passes through the two orifices.
12. The bioreactor of claim 6 wherein the first cannula unit of the arbor assembly further comprises an orifice and the second cannula unit comprises an orifice, wherein the first and second cannula units are arranged such that they confront one another along a longitudinal axis that passes through the two orifices.
