摘要：
A prosthesis can include a shell and a needle guard coupled to a posterior portion of the shell. The shell can include a laminate having a base layer, a top layer, and a soft silicone gel intermediate layer disposed between the base layer and the top layer and of sufficient thickness for self-sealing of a needle hole therethrough. The needle guard can include a plurality of offset layers of offset, puncture-resistance structures that, in an expanded state, (i) collectively form a concave shape and (ii) provide a concave exterior surface along the posterior portion of the prosthesis for approximating a human anatomical feature. The needle guard can have a shape memory characteristic for urging the prosthesis toward the expanded state.
