Abstract

A medical implant assembly and method having a medical implant, e.g. a breast prostheses, attached 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. The biological interface comprises a plurality of apertures along its periphery, and attaches to the medical implant by receiving a plurality of attachment flaps or appendages located on the exterior surface of the medical implant within or through the apertures. The attachment of the biological interface is such that the assembly remains intact even where the attachment flaps loosen upon expansion of the implant after insertion into a host, as where the implant is therein injected to a desired dimension.

Claims

1. A breast implant assembly for implantation in a patient, comprising:

(a) a breast implant having a flexible deformable silicone elastomeric shell, wherein said shell containing a liquid or a gel;

(b) a continuous capsular contracture inhibiting layer of an acellular dermal material (i) attached to, (ii) intimately engaged with, and (iii) following the contour of only a portion of an exterior surface of said shell by engaging attachment flaps located on said exterior surface of said shell and said attachment flaps are continual to said exterior surface of said shell; and

(c) attachment flaps receiving apertures of said continuous capsular contracture inhibiting layer shaped to receive said attachment flaps,

wherein said acellular dermal material is a matrix or foundation for tissue regeneration and revascularization of natural tissue of said patient,

wherein said breast implant assembly to be pressure fit in said patient, and

wherein there is no requirement to suture said continuous layer of acellular dermal material to the natural tissue of said patient.
