The invention relates to a method of shaping products made of HDPE or PA, particularly spatial shaping of HDPE or PA tubes, in which HDPE or PA semi-finished product is shaped. A semi-finished product from HDPE or PA is first heated to temperature T close to melting temperature T.sub.g of the material so that the material remains in a solid state, T the semi-finished product made of HDPE or PA is left at this temperature for time period t.sub.1 required to obtain plasticity and to disrupt completely or partially the crystalline or semi-crystalline structure of the HDPE or PA material and for relaxing the internal tension of the HDPE or PA material and for restoring the amorphous or partially amorphous state of the material, whereupon the HDPE or PA semi-finished product is inserted into a shaping fixture and the temperature of the HDPE or PA material gradually decreases to ambient temperature.

The invention also relates to a device for performing the method.

A medical device includes a balloon expanded scaffold (or stent) crimped to a catheter having a balloon. The scaffold is crimped to the balloon by a process that includes using protective polymer sheaths or sheets during crimping, and resetting the sheaths or sheets during the crimping to avoid or minimize interference between the polymer material and scaffold struts as the scaffold is reduced in size. Balloon pressure is adjusted when the polymer material is reset.

A method for forming a composite tube includes the steps of: braiding a plurality of strips to form a workpiece tube; bending the workpiece tube to form a bend; and extending the length of the workpiece tube by continuing the braiding step.
