ABSTRACT:
A modular prosthesis for implantation beneath the skin is described. The modular prosthesis comprises a universal shell, which is relatively thin and substantially planar, having the general size and shape required for the prosthesis. The prosthesis is a composite structure consisting of the universal shell and one or more shims. The shims are individually cut from a shim sheet of a biocompatible material of suitable thickness. The shim sheet has a shell-contacting surface with means thereon for attaching the shim to the shell. The shims are cut from the shim sheet and attached to the shell to construct a prosthesis providing the desired contour to the overlying tissue following implantation. In a preferred embodiment, the universal shell and the shims have releasable interlocking means therebetween which permits changing the shims or adding shims to the prosthesis as required.
