Abstract
An implantable device includes a first sealed flexible shell configured for implantation within a breast of a human subject, an elastic filler material contained within the first sealed flexible shell, and a second sealed flexible, inelastic shell, which is disposed within the elastic filler material inside the first sealed flexible shell and is inflated with a volume of gas. The second shell includes a material selected such that a root-mean-square (RMS) sound pressure caused by a deformation of the second shell not exceeding 50 mm does not exceed 20 micro-Pascals.
Claims8
An implantable device, comprising:
- a first sealed flexible shell configured for implantation within a breast of a human subject;
- an elastic filler material contained within the first sealed flexible shell;
- a second sealed flexible, inelastic shell, which is disposed within the elastic filler material inside the first sealed flexible shell and is inflated with a volume of gas, the second shell comprising a material selected such that a root-mean-square (RMS) sound pressure caused by a deformation of the second shell not exceeding 50 mm does not exceed 20 micro-Pascals.
A method for manufacturing an implantable device, the method comprising:
- providing a first sealed flexible shell configured for implantation within a breast of a human subject;
- filling the first sealed flexible shell with an elastic filler material;
- providing a second sealed flexible, inelastic shell fabricated of a material selected such that a root-mean-square (RMS) sound pressure caused by a deformation of the second shell not exceeding 50 mm does not exceed 20 micro-Pascals;
- inflating the second sealed flexible shell with a volume of gas;
- and
- disposing the second sealed flexible, inelastic shell within the elastic filler material inside the first sealed flexible shell.
