First Claim
Patent Images
1. A prosthesis for implantation in a human being, the prosthesis comprising:
- an implantable member including an exterior surface defined by an anterior face and a posterior face;
one of the anterior face and the posterior face including a plurality of fixation regions in a radiating configuration defined by a texture, roughness or sheen different from a respective texture, roughness or sheen of a balance of said one of the anterior face and posterior face;
the prosthesis being structured such that when implanted adjacent a muscle group in a human being, the plurality of fixation regions can be generally aligned with an alignment of said muscle group.

Abstract
A soft prosthetic implant shell, such as a silicone breast implant shell, that has discrete fixation surfaces thereon for tissue adhesion. The fixation surfaces may be provided on the posterior face of the shell, as well as either on the periphery or at discrete areas on the anterior face. Band-shaped fixation surfaces may be provided on the anterior face of the shell to generally match the angle of pectoralis major or pectoralis minor muscle groups. The fixation surfaces may be roughened areas of the shell, or may be separate elements adhered to the shell.

8. A method of augmenting or reconstructing a breast of a human being, the method comprising:
-
providing an implantable member including an exterior surface defined by an anterior face and a posterior face, wherein one of the anterior face and the posterior face includes at least one generally elongated fixation region defined by a texture, roughness or sheen different from a respective texture, roughness or sheen of a balance of said one of the anterior face and posterior face; and implanting the implantable member into a breast of a human being such that the fixation region of the implantable member generally aligns with one of the pectoralis major muscle group and the pectoralis minor muscle group. - View Dependent Claims (9)

10. A method of making a mammary prosthesis comprising the steps of:
-
providing a fillable elastomeric shell having an exterior surface comprising an anterior face and a posterior face; and texturing only a portion of the exterior surface to form a band-shaped fixation region across at least one of the anterior face and the posterior face. - View Dependent Claims (11, 12)
