Abstract
This invention provides an artificial sphincter including a component coated on at least one contacting surface with a polymeric material, the polymeric coating adapted to expand and return to an original configuration and to prevent or inhibit wear or abrasion of the contacting surface. The polymeric material is parylene in some embodiments. The component adapted for inflation and deflation may be a cuff formed from silicon and adapted to surround a urethra or a rectum. Also provided by the present invention is a method of depositing a coating to a surface of an inflatable component by providing a vacuum chamber system having an inner chamber positioned within an outer chamber. At least one coating material is introduced into at least one of the inner and outer chambers to deposit a coating onto an exposed surface of the component. This invention also provides methods of masking portions of surfaces of an inflatable component to prevent a coating from being deposited on the masked portion.
