Abstract
A method for forming a balloon for use in a balloon catheter by depositing a film over the exterior surface of a substrate. The film includes a plurality of layers in which one of the layers is a polyimide and another is made of a metallic material which heats in response to the application of electromagnetic energy. The substrate is removed to leave a balloon in the desired shape.
Claims14
A method of forming a balloon for use in a balloon catheter, the method comprising the steps of:
- providing a substrate having an exterior surface configuration which corresponds to a desired shape of the balloon in a predetermined condition;
- depositing a film over the exterior surface of the substrate wherein the film is defined by a plurality of layers of substrate coatings, with at least one layer formed from a polyimide polymer material and another layer formed from a metallic material which heats in response to an application of electro-magnetic energy thereto;
- and
- removing the substrate within the film to leave a balloon of the desired shape.
