Abstract
A method for forming a balloon provides a preform that encloses an internal space. The preform is pre-heated to a shaping temperature by passing a heated gas or fluid via an inlet of the preform into the internal space. The preform is then shaped the preform into a balloon. A device is configured to heat a preform using heated gas or fluid to decouple heating from the temperature of a shaping tool.
