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.
Claims20
A penile prosthesis comprising:
- a reservoir;
- a pump assembly fluidly coupled to the reservoir;
- and
- a flexible inflatable cylinder fluidly coupled to the pump by an interconnecting tube;
- wherein at least a portion of the cylinder is coated with a parylene material adapted to prevent or inhibit wear or degradation of the cylinder at bend corners or pinch points of crease lines associated with folding or bending of the cylinder.
A penile prosthesis comprising:
- a reservoir;
- a pump and valve assembly coupled to the reservoir;
- and
- at least one cylinder fluidly coupled to the pump and valve assembly;
- wherein at least a portion of the cylinder is coated with a parylene material adapted to prevent or inhibit wear or degradation of the cylinder at bend corners or pinch points of crease lines associated with folding or bending of the cylinder.
