Abstract
This invention relates to a mammary prosthesis and a method of implanting same. The prosthesis comprises a flexible backing and a soft front envelope, for example, of the inflatable or prefilled type. The flexible backing defines, at least one internal passageway or compartment into which rigidifying material may be forced or emplaced. Upon setting of the rigidifying material in the passageways or compartments, the backing loses a substantial part, if not all, of its flexibility. The rigidified backing thereafter prevents the contracture of natural fibrous tissues generated around the front envelope and backing in a way to prevent hardening of the prosthesis and/or palpable prosthesis edges prevalent with prior art devices.
