Abstract

Soft tissue supports, soft tissue implants, and methods of making and using soft tissue supports are disclosed. One soft tissue support includes a unitary piece of processed porous tissue material having an anterior portion and a posterior portion. The anterior and posterior portions define a cavity therebetween. The cavity is sized to receive a breast implant therein. The cavity has at least one opening sized to receive the breast implant therethrough. One soft tissue implant includes the soft tissue support and a breast implant positioned within the cavity of the soft tissue support. The implant may further include a soft tissue graft configured to support the processed porous tissue material and the breast implant. A method of using a soft tissue support includes inserting a breast implant into the soft tissue support, and implanting the soft tissue support containing the breast implant in the cavity.

First claim

What is claimed is:

1. A soft tissue support comprising:
a unitary piece of processed porous tissue material having an anterior portion and a posterior portion, the anterior and posterior portions defining a cavity therebetween, the cavity sized to receive a breast implant therein, the cavity having at least one opening sized to receive the breast implant therethrough, wherein the at least one opening is provided at a periphery of the processed porous tissue material between the anterior portion and the posterior portion.

2. The soft tissue support of claim 1 , wherein the processed porous tissue material comprises a dispersed soft tissue material.

3. The soft tissue support of claim 2 , wherein the dispersed soft tissue material has been frozen, freeze-dried, and/or plasticized.

4. The soft tissue support of claim 2 , wherein the dispersed soft tissue material lacks both a non-naturally occurring crosslinker and a non-naturally occurring carrier.

5. The soft tissue support of claim 2 , wherein the dispersed soft tissue material is molded to form the anterior and posterior portions defining the cavity.

6. The soft tissue support of claim 1 , wherein the anterior portion has a thickness which is less than a thickness of the posterior portion.

7. The soft tissue support of claim 1 , wherein the anterior and posterior portion each have an upper portion and a lower portion, the respective upper portions having a thickness which is greater than a thickness of the respective lower portions.

8. The soft tissue support of claim 1 , wherein the anterior and posterior portions have a shape which is at least partially curved.

9. The soft tissue support of claim 8 , wherein the shape of the anterior and posterior portions is round or elliptical.

10. The soft tissue support of claim 1 , wherein the cavity has a shape which is at least partially curved.

11. The soft tissue support of claim 10 , wherein the shape of the cavity is round or elliptical.

12. The soft tissue support of claim 1 , wherein the cavity has a volume of from 40 to 100 cubic centimeters.

13. A soft tissue support comprising:
a unitary piece of processed porous tissue material having an anterior portion and a posterior portion, the anterior and posterior portions defining a cavity therebetween, the cavity sized to receive a breast implant therein, the cavity having at least one opening sized to receive the breast implant therethrough, wherein the at least one opening is provided in the posterior portion.

14. The soft tissue support of claim 13 , wherein the processed porous tissue material comprises a dispersed soft tissue material.

15. The soft tissue support of claim 14 , wherein the dispersed soft tissue material has been frozen, freeze-dried, and/or plasticized.

16. The soft tissue support of claim 14 , wherein the dispersed soft tissue material lacks both a non-naturally occurring crosslinker and a non-naturally occurring carrier.

17. The soft tissue support of claim 14 , wherein the dispersed soft tissue material is molded to form the anterior and posterior portions defining the cavity.

18. The soft tissue support of claim 13 , wherein the anterior portion has a thickness which is less than a thickness of the posterior portion.

19. The soft tissue support of claim 13 , wherein the anterior and posterior portion each have an upper portion and a lower portion, the respective upper portions having a thickness which is greater than a thickness of the respective lower portions.

20. The soft tissue support of claim 13 , wherein the anterior and posterior portions have a shape which is at least partially curved.

21. The soft tissue support of claim 20 , wherein the shape of the anterior and posterior portions is round or elliptical.

22. The soft tissue support of claim 13 , wherein the cavity has a shape which is at least partially curved.

23. The soft tissue support of claim 22 , wherein the shape of the cavity is round or elliptical.

24. The soft tissue support of claim 13 , wherein the cavity has a volume of from 40 to 100 cubic centimeters.

25. A soft tissue support comprising:
a unitary piece of processed porous tissue material having an anterior portion and a posterior portion, the anterior and posterior portions defining a cavity therebetween, the cavity sized to receive a breast implant therein, the cavity having at least one opening sized to receive the breast implant therethrough, wherein the at least one opening has a cross-sectional area less than a cross-sectional area of the cavity.

26. The soft tissue support of claim 25 , wherein the processed porous tissue material comprises a dispersed soft tissue material.

27. The soft tissue support of claim 26 , wherein the dispersed soft tissue material has been frozen, freeze-dried, and/or plasticized.

28. The soft tissue support of claim 26 , wherein the dispersed soft tissue material lacks both a non-naturally occurring crosslinker and a non-naturally occurring carrier.

29. The soft tissue support of claim 26 , wherein the dispersed soft tissue material is molded to form the anterior and posterior portions defining the cavity.

30. The soft tissue support of claim 25 , wherein the anterior portion has a thickness which is less than a thickness of the posterior portion.

31. The soft tissue support of claim 25 , wherein the anterior and posterior portion each have an upper portion and a lower portion, the respective upper portions having a thickness which is greater than a thickness of the respective lower portions.

32. The soft tissue support of claim 25 , wherein the anterior and posterior portions have a shape which is at least partially curved.

33. The soft tissue support of claim 32 , wherein the shape of the anterior and posterior portions is round or elliptical.

34. The soft tissue support of claim 25 , wherein the cavity has a shape which is at least partially curved.

35. The soft tissue support of claim 34 , wherein the shape of the cavity is round or elliptical.

36. The soft tissue support of claim 25 , wherein the cavity has a volume of from 40 to 100 cubic centimeters.

37. A soft tissue support comprising:
a unitary piece of processed porous tissue material having an anterior portion and a posterior portion, the anterior and posterior portions defining a cavity therebetween, the cavity sized to receive a breast implant therein, the cavity having at least one opening sized to receive the breast implant therethrough, wherein the cavity comprises a plurality of openings.

38. The soft tissue support of claim 37 , wherein the plurality of openings are distributed around a periphery of the processed porous tissue material between the anterior portion and the posterior portion.

39. The soft tissue support of claim 37 , wherein the processed porous tissue material comprises a dispersed soft tissue material.

40. The soft tissue support of claim 39 , wherein the dispersed soft tissue material has been frozen, freeze-dried, and/or plasticized.
