This invention discloses a process for preparation of a balloon expandable biodegradable polymer stent with thin struts (strut thickness 130 m or less, preferably 100-110 m) with high fatigue and radial strength. The invention discloses a process for the preparation of a biodegradable polymer stent which involves deforming an extruded biodegradable polymer tube axially at a first predefined temperature by applying an axial force for a first predefined time interval. The process further includes radially expanding the axially stretched tube at a second predefined temperature by pressurizing the tube with an inert gas in one or more stages, the pressure applied in each successive stage being higher than the pressure applied in a previous stage.

A method for forming plastic preforms into plastic containers using at least one device for forming preforms into containers, wherein preforms are acted upon by a flowable and, in particular, gas-forming medium and are formed into the containers, wherein the preforms are acted upon with different pressure levels and the flowable medium is stored in at least two reservoirs and is supplied from these reservoirs to the preforms and at least one of these reservoirs is supplied with the flowable medium by a pressure supply device, wherein the target pressure in at least one reservoir is controlled, and wherein this target pressure is compared with an actual pressure in this reservoir. A value characteristic of this comparison is determined. An offset value is controlled on the basis of this value and is controlled in such a way that a predetermined pressure and the target pressure is set in the reservoir.
