the invention discloses a process for the preparation of a biodegradable 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 is followed by 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 . the process further comprises laser cutting a specific pattern of scaffold structure on the expanded tube and then crimping the laser cut stent on the balloon of delivery catheter in a sterile environment in multiple stages .
