ABSTRACT:
A self-sealing valve useful in a fluid fillable article, such as a mammary prosthesis, includes first and second planar members which are bonded together so as to leave an elongated unbonded portion therebetween. Openings are formed for communication between the unbonded portion and the inside and outside of a fluid fillable article containing the valve. The openings are offset from one another so that the openings and the unbonded portion form a normally open channel through the valve. At least one planar member is sufficiently flexible to close the channel responsive to pressure from within a fluid fillable member containing the valve.
