Abstract

Compositions and methods are disclosed for filling prostheses for implantation into human soft tissue. The compositions comprise at least one nonionic surfactant, such as a polysorbate, which can be provided to fill a physiologically compatible shell or containment sac of the prosthesis. The liquid compositions of the present invention have a relatively high viscosity and are quickly absorbed from body tissues, metabolized and excreted with no known adverse effect. The compositions can be injected into the physiologically compatible shell either before, during or after the surgical implantation procedure.
