  • Method and apparatus for preventing and treating anaerobic infections
    Patent number: 5003993
    Abstract: In the method disclosed herein for preventing and treating anaerobic infectons in the region of the penile sulcus, a radially compliant ring, formed of a helically coiled resilient filament, is passed over the penile head and then seated in the sulcus behind the corona, the foreskin having been rolled back to expose the sulcus. The foreskin may then be released but is prevented from moving forward to cover the sulcus and penile head by the ring, thus allowing air to circulate in the region of the sulcus.
