Engineers at MedPlast (Elkhorn, WI) developed a new approach to a product called pessary balloons that includes a molded part, a check ball and a glued-on silicone extrusion.

The recently developed assembly is latex-free. Previous designs had been 100% latex, but medical device manufacturers globally are moving away from latex because it contains proteins that can cause an allergic reaction.

Silicone has become the preferred replacement in pessary applications, while in other devices elastomers and other polymers are used. Silicone, however, can be difficult to manufacture....
