Abstract

A medical implant assembly and method having a medical implant, e.g. a breast prostheses, affixed to a biological interface. The biological interface is comprised of a dermal material with capsular contracture inhibiting properties so that once the medical assembly is inserted into the host, the biological interface, which is intimately coupled to the implant, prevents/reduces capsular contracture formation around the implant.

Claims

1. A medical implant system for use in a host, comprising:

a medical implant having an exterior structural surface; and

a dermal material defining a discrete component layer that is separate from but secured to the exterior structural surface of the medical implant, the dermal material promoting tissue regenerative repair and inhibiting capsular contracture in tissue around the exterior surface of the implant when the medical implant system is placed within a host.

2. The system of claim 1, wherein the dermal material comprises an acellular dermal graft.

3. The system of claim 1, wherein the dermal material comprises an acellular dermal matrix.

4. The system of claim 1, wherein the medical implant is a breast implant.

6. The system of claim 1, wherein the dermal material is biotechnically prepared.

7. The system of claim 1, wherein the dermal material is sutured to the exterior surface of the medical implant.

8. The system of claim 1, wherein the dermal material is adhered to the exterior surface of the medical implant.

5. (canceled)

9. A method for reducing capsular contracture associated with a medical implant having an exterior structural shell, comprising:

securing a separate layer of non-bioabsorbable dermal material to the exterior structural shell of the medical implant, the dermal material defining a discrete component layer having tissue regenerative properties; and

positioning the secured layer of dermal material and the medical implant in an implant recipient.

10. The method of claim 9, wherein the non-bioabsorbable dermal material is immunologically benign.

11. The method of claim 9, wherein the medical implant is a breast implant.

12. The method of claim 9, wherein the non-bioabsorbable dermal material comprises an acellular dermal material.

14. The method of claim 9, wherein the layer of non-bioabsorbable dermal material encompasses the medical implant.

13. (canceled)

15. A medical implant system for use in a host, comprising:

a medical implant having an elastomeric structural shell with a contour; and

a dermal material intimately engaged to, but defining a discrete component separate from, the elastomeric shell to allow the dermal material to follow the contour of the elastomeric shell, wherein the dermal material is non-bioabsorbable and has tissue regenerative properties.

16. The system of claim 15, wherein the medical implant is a breast implant.

18. The system of claim 15, wherein the dermal material comprises xenograft.

19. The system of claim 15, wherein the dermal material is immunologically benign.

17. (canceled)

20. A method for reducing capsular contracture associated with a medical implant when the implant is placed in a host, comprising:

selecting a medical implant having a structural exterior surface defining an implant geometry;

securing a separate layer of dermal material to the structural exterior surface of the medical implant, the dermal material defining a discrete component layer having capsular contracture inhibiting properties and further comprising inner and outer dermal material surfaces defining a dermal layer geometry;

creating a tissue pocket in the host, the tissue pocket having a pocket surface defining a pocket geometry;

positioning the medical implant and the secured layer of dermal material within the tissue pocket; and

wherein the pocket geometry, implant geometry, and dermal layer geometry are selected to cause the dermal material to closely engage the medical implant and the tissue pocket so as to optimize the contracture inhibiting properties of the dermal material in the host.
