Abstract
Abstract A device for controlling urinary incontinence in a human female, comprising a resilient pad, configured to seal against and occlude the urethral meatus of the user. The pad includes a base that is adapted to seat against the vestibule of the user's vulva, anteriorly of the vaginal orifice, thereby covering the urethral meatus. An adhesive is provided on the base to seal against and occlude the urethral meatus, and to retain the pad in place against the vestibule. The pad has lateral edges that fit inside the labia minora of the user, to aid in retention of the device. The surface of the pad opposite the base is formed into a longitudinal stiffening ridge that extends into the interlabial space. A handle is attached to the ridge to facilitate removal.
