ABSTRACT:
A method and apparatus for packaging a fluid containing prosthesis adapted to be implanted in a sterile condition involves filling a closable, permeable fluid containing housing within the prosthetic device with a fluid. The prosthetic device is then enclosed within a substantially fluid impenetrable enclosure that is filled with a fluid with activities which substantially match the activities of the fluid within the prosthetic device. Thus, even where the prosthetic device contains a physiological solution, by incorporating a solution of equal solute concentration within the enclosure that surrounds the prosthetic device, the tendency for osmosis to occur across the barrier defined by the walls of the prosthetic device can be adequately controlled. The enclosure may then be enclosed within an outer bag which may be handled by a non-sterile nurse, preparatory to implantation by a surgeon. In this way, it is possible to ship a prosthetic device in a fluid filled state despite the tendency for migration through the walls of the device by establishing mass transfer equilibrium within the package.
