Abstract

A support assembly for supporting a biological product (e.g., membrane) in an operative position. The support assembly has a base and a cover. A membrane receiving portion of the base defines a plurality of perforations that extend between top and bottom surfaces of the product receiving portion. The cover is releasably coupled to the base in a product-covering position in which the cover overlies the product receiving portion of the base. In the operative position, the biological product engages the top surface of the product receiving portion and the bottom surface of the cover.

First claim

What is claimed is:

1. A membrane product package comprising:
a base having a longitudinal axis and comprising a product receiving portion, the product receiving portion having a top surface and an opposed bottom surface that are spaced apart relative to a vertical axis that is perpendicular to the longitudinal axis of the base, wherein the product receiving portion comprises a traction-creating feature, wherein the traction-creating feature comprises one or more of the following: (i) a rough top surface, (ii) a plurality of perforations extending between the top and bottom surfaces of the product receiving portion, (iii) a surface comprising a plurality of channels, (iv) a surface comprising a plurality of grooves, (v) a surface comprising a plurality of indentations, or (vi) a surface comprising a plurality of porations; and
a cover having a longitudinal axis, a top surface, and an opposed bottom surface, wherein the cover is configured for releasable coupling to the base in a product-covering position, and wherein, in the product-covering position, the cover overlies the product receiving portion of the base; and
a membrane positioned in an operative position between the product receiving portion of the base and the cover, wherein the membrane is a placental tissue product, a tissue graft, an in vitro cultured graft, a tendon graft, or a bioengineered membrane comprising living cells, wherein the membrane is positioned in engagement with at least a portion of the top surface of the product receiving portion of the base and at least a portion of the bottom surface of the cover,
wherein the base and the cover cooperate to support the membrane in the operative position.

2. The membrane product package of claim 1 , wherein the base further comprises a handling portion position adjacent to the product receiving portion relative to the longitudinal axis of the base.

3. The membrane product package of claim 2 , wherein, in the product-covering position, the cover does not overlap with the handling portion of the base.

4. The membrane product package of claim 1 , wherein in the product-covering position, the longitudinal axis of the cover is positioned in a substantial alignment with the longitudinal axis of the base.

5. The membrane product package of claim 4 , wherein the product receiving portion of the base has a longitudinal length and a width, wherein the cover has a longitudinal length and a width, and wherein the longitudinal length of the cover 1 s substantially equal to the longitudinal length of the product receiving portion.

6. The membrane product package of claim 5 , wherein the width of the cover is substantially equal to the width of the product receiving portion.

7. The membrane product package of claim 1 , wherein the cover has a plurality of comers, and wherein at least one of the comers of the cover is rounded.

8. The membrane product package of claim 7 , wherein the cover has four rounded comers.

9. The membrane product package of claim 8 , wherein the product receiving portion of the base has two rounded comers, and wherein, in the product-covering position, two rounded comers of the cover overlie the two rounded comers of the product receiving portion of the base.

10. The membrane product package of claim 1 , wherein the traction-creating feature of the product receiving portion comprises a plurality of perforations.

11. The membrane product package of claim 10 , wherein the plurality of perforations of the product receiving portion of the base are substantially evenly distributed throughout the product receiving portion.

12. The membrane product package of claim 10 , wherein the plurality of perforations of the product receiving portion of the base are randomly distributed throughout the product receiving portion.

13. The membrane product package of claim 10 , wherein each perforation of the plurality of perforations has a respective diameter ranging from about 0.1 mm to about 5 mm.

14. The membrane product package of claim 10 , wherein each perforation of the plurality of perforations has a respective center point, and wherein the center points of neighboring perforations are spaced apart by a distance ranging from about 0.35 mm to about 10 mm.

15. The membrane product package of claim 1 , wherein the membrane is attached to the top surface of the product receiving portion of the base at least one attachment point.

16. The membrane product package of claim 15 , wherein the membrane is attached to the top surface of the product receiving portion of the base at least three attachment points.

17. The membrane product package of claim 15 , wherein the top surface of the product receiving portion of the base is attached to the cover at least one attachment point.

18. The membrane product package of claim 15 , wherein the cover is attached to the membrane at least one attachment point.

19. The membrane product package of claim 18 , wherein the cover is attached to the membrane at least two attachment points.

20. The membrane product package of claim 18 , wherein the top surface of the product receiving portion of the base is attached to the cover at least one attachment point.

21. The membrane product package of claim 1 , wherein the top surface of the product receiving portion of the base is attached to the cover at least one attachment point.

22. The membrane product package of claim 1 , wherein the membrane is a chorionic membrane product.

23. The membrane product package of claim 1 , wherein the membrane is an amniotic membrane product.

24. The membrane product package of claim 1 , wherein the membrane and the top surface of the product receiving portion of the base have sufficient surface traction to maintain the membrane in the operative position following removal of the cover from the base.

25. The membrane product package of claim 1 , wherein the membrane and the top surface of the product receiving portion of the base have a first surface traction, wherein the membrane and the cover have a second surface traction, and wherein the second surface traction is lower than the first surface traction.

26. The membrane product package of claim 1 , wherein the traction-creating feature of the product receiving portion comprises a rough top surface.

27. A method of producing a membrane product package, comprising:
positioning a membrane in an operative position between a product receiving portion of a base and a cover, wherein the membrane is positioned in engagement with at least a portion of a top surface of the product receiving portion of the base and at least a portion of a bottom surface of the cover, and wherein the membrane is a placental tissue product, a tissue graft, an in vitro cultured graft, a tendon graft, or a bioengineered membrane comprising living cells, and
wherein the product receiving portion of the base comprises a traction-creating feature, and wherein the traction-creating feature comprises one or more of the following: (i) a rough top surface, (ii) a plurality of perforations extending between the top and bottom surfaces of the product receiving portion, (iii) a surface comprising a plurality of channels, (iv) a surface comprising a plurality of grooves, (v) a surface comprising a plurality of indentations, or (vi) a surface comprising a plurality of porations.

28. The method of claim 27 , wherein the step of positioning th
