  • Patent number: 5520613
    Abstract: A device for expanding the connective fatty tissue and correcting inverted nipples and improving symmetry of the human breast by means of gentle suction generated by respiratory means. The hollow dome is constructed of tinted, low-density, polyethylene which enables the user to monitor the degree of expansion she desires. The surrounding rim assures an air tight seal with the skin tissue. The pliable, high tensile quality of the hollow dome allows the user to squeeze and change the shape of the hollow dome on various locations on the breast to uplift and improve cleavage. A threaded nipple extends from top center of the exterior of the hollow dome which is attached to a pliable breathing tube and is fitted with a removable mouthpiece to facilitate orally evacuating the air surrounding the breast. A valve-timer controls the input and output of atmospheric pressure which creates a vacuum around the breast, and can be maintained for a selected number of seconds and minutes by the individual needs of the user.
