摘要：
There is provided a tubular workpiece for blow-molding into an inflatable ballooncomponent. The tubular workpiece is a raw tube having a lumen and composed of athermoplastic polymer, the tube having an asymmetric wall thickness such thatwhen the tube is preheated in a mold to a temperature sufficient to soften the materialof the tube and inflated with a gas to generally uniformly stretch the materialof the tube, the tube forms a balloon component. The balloon may be non-uniformin wall thickness depending on the type of mold used. The balloon may be attachedaccording to conventional means to a hollow tube to produce a tracheostomy device.
