Abstract: A medical device including a medical device metallic substrate component, with perforations therethrough, attached to a medical device polymeric component abutting the thin metallic film component. The medical device also includes a polymeric sleeve covering the perforations and at least a portion of the polymeric component abutting the metallic substrate component. Moreover, the polymeric sleeve intrudes into the perforations and joins the metallic substrate component to the polymeric component. A method for attaching a medical device metallic substrate component to a medical device polymeric component includes forming a plurality of perforations in the medical device metallic substrate component and abutting the medical device polymeric component against the medical device metallic substrate component. Subsequently, a polymeric sleeve is applied over the perforations and at least a portion of the abutted medical device polymeric component.

Abstract: A medical device including a medical device thin metallic film component (such as a thin metallic angioplasty balloon), with perforations therethrough, attached to a medical device polymeric component (e.g., a polymeric tubular catheter) abutting the thin metallic film component. The medical device also includes a polymeric sleeve covering the perforations and at least a portion of the polymeric component abutting the thin metallic film component. Moreover, the polymeric sleeve intrudes into the perforations and joins the thin metallic film component to the polymeric component. A method for attaching a medical device thin metallic film component (for example a thin metallic film angioplasty balloon) to a medical device polymeric component (e.g., a tubular polymeric catheter) includes forming a plurality of perforations in the medical device thin metallic film component and abutting the medical device polymeric component against the medical device thin metallic component.
