1. A breast prosthesis for implantation in a human being, the prosthesis comprising:
- an implantable member comprising an elastomeric shell including an exterior surface defined by an anterior face and a posterior face; and
a fixation region defined by a texture molded into the anterior face of the shell, the texture being different from a balance of the exterior surface of the shell, the fixation region comprising a plurality of fixation regions in a radiating configuration;
the prosthesis being structured such that when implanted adjacent a muscle group in a human being, the fixation region 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.

7. A mammary prosthesis comprising:
-
a implantable member comprising a silicone elastomeric shell including an exterior surface defined by an anterior face, a posterior face and a peripheral region between the anterior face and the posterior face, said exterior surface comprising at least one generally elongated fixation region defined by a texture molded into the exterior surface of the shell which is different from a balance of the exterior surface of the shell, the fixation region extending along the peripheral region and across at least one of the posterior face and the anterior face; the fixation region being configured such that when the prosthesis is implanted in a breast of a human being, the fixation region generally aligns with an alignment of at least one of a pectoralis major muscle group and a pectoralis minor muscle group. - View Dependent Claims (8, 9)

12. A breast prosthesis for implantation in a human being, the prosthesis comprising:
-
an implantable member comprising an elastomeric shell including an exterior surface defined by an anterior face and a posterior face; a fixation region defined by a first texture integrally molded into the anterior face of the shell; a second texture integrally molded into the posterior surface of the shell, the second texture being a less textured surface than the first texture. - View Dependent Claims (13)

14. A breast prosthesis for implantation in a human being, the prosthesis comprising:
-
an implantable member comprising an elastomeric shell including an exterior surface defined by an anterior face and a posterior face; and a fixation region defined by a texture molded into the anterior face of the shell and having a substantially constant width of between about 2 mm and about 15 mm, the texture being different from a balance of the exterior surface of the shell; the prosthesis being structured such that when implanted adjacent a muscle group in a human being, the fixation region can be generally aligned with an alignment of said muscle group.

15. A breast prosthesis for implantation in a human being, the prosthesis comprising:
-
an implantable member comprising an elastomeric shell including an exterior surface defined by an anterior face and a posterior face; and a fixation region defined by a texture molded into the anterior face of the shell, the texture being different from a balance of the exterior surface of the shell, and the balance of the exterior surface being a matte finish and being relatively less textured than the fixation region texture; the prosthesis being structured such that when implanted adjacent a muscle group in a human being, the fixation region can be generally aligned with an alignment of said muscle group.
