Parylene-coated components for inflatable penile prosthesis
First Claim
1. A multi-component penile prosthesis comprising one or more components having flexible expanding and contracting surfaces coated on at least one contacting surface with a parylene material adapted to a) expand and return to an original configuration, b) reduce the coefficient of friction of the contacting surface, and c) prevent or inhibit wear or degradation of the flexible expanding and contracting surface at bend corners or pinch points of crease lines associated with folding or bending of the one or more components.

Abstract
A penile prosthesis beneficially includes components coated with parylene in order to increase product life and reduce wear. In particular, components of the inflatable cylinder benefits from having been coated with parylene. The parylene-coated cylinder components are resistant to wear generated by pinching of the cylinder when the cylinder is in a flaccid state. The parylene-coated cylinder may be formed by masking a tube of silicone (or other appropriate material) and vapor coating the silicone tube with parylene. Further, where a double walled cylinder is used, each of two tubes making up the double wall cylinder can have their surfaces coated with parylene, thus increasing cylinder life and avoiding wear.
