A manual, non-powered device intended to be used by women to provide Kegel exercise (alternate contraction and relaxation of perineal muscles) to treat urinary stress incontinence, sexual dysfunction, or to tone the muscles of the pelvic floor. It is typically inserted into the vagina and is available in a variety of designs that commonly includes a spring-loaded, split, cantilevered cylinder that requires the voluntary contraction of the vagina to squeeze it together, or a solid metal, profiled weight that is gripped by the vaginal muscles as gravity pulls it downward. It does not include biofeedback functionality. This is a reusable device.
