Abstract
A thin wall balloon for a balloon catheter is formed by depositing a film (such as polyimide) over a substrate which has an exterior surface configuration corresponding to a desired shape of the balloon in an inflated (or deflated) condition. After the polyimide film is cured, the substrate is removed from within the polyimide film by chemically dissolving the substrate.
