  • PAPILLA SPREADER
    Publication number: 20080015416
    Abstract: The present invention provides apparatus and methods for facilitating entry through a bodily opening comprising a spreader having a plurality of arms, each of the arms being formed of a resilient material and shaped so that the distal ends tend to be spaced apart from each other when the spreader is in an open position.
