Abstract
A laminate useful as a component of a medical implant, for example, useful as a component of an inflatable tissue expander. The laminate includes a base layer, an intermediate layer, and a top layer. When used as a component of a tissue expander, the laminate enables an internal chamber pressure of about 2.5 psi with an expander exterior compressive force of about 40 lbs.
Claims14
A laminate suitable for use as a shell for flexible, Tillable prosthesis, said laminate comprising:
- a base layer;
- a top layer;
- and
- an intermediate layer disposed between the base layer and the top layer, the intermediate layer being a silicone elastomer of sufficient thickness for self-sealing of a needle hole therethrough and comprising a material with a loss modulus at 0.1, 1 and 10 Hz at 1840, 4820 and 12400 Pa, respectively.
A laminate suitable for use as a shell for flexible, fillable prosthesis, the laminate comprising:
- a base layer;
- a top layer;
- and
- an intermediate layer disposed between the base layer and the top layer, the intermediate layer being a silicone elastomer of sufficient thickness for self-sealing of a needle hole therethrough and comprising a material with a complex viscosity at 0.1, 1 and 10 Hz at 7720, 1520 and 358 Pa·s.
