Abstract
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.
