Abstract

A technique for making individualized silicone rubber intravaginal balloons is described. The method entails investing alginate vaginal impressions in silicone rubber and casting a resin model which is then dipped repeatedly in a Silastic Dispersion® (Dow Corning, Q7–2213). The range of forces developed by circumvaginal muscles during maximum contractions was determined to be 0.5–4 lbs. Pressure-volume relationships of the balloons showed that the pressure of filling fluid was an accurate replica of the mean pressure in the vagina.
