Abstract
The invention is to methods of deploying polymeric biodegradable or non biodegradable stents by use of stepwise creases in the pressure placed upon the inner diameter of the stent to slowly increase the stent diameter. In one embodiment, the pressure on the interior stent diameter is slowly increased. The stent is allowed to acclimate to this diameter for a set period of time, and then the pressure is again increased. This series of steps continues until the stent reaches its final diameter and a final period of acclimatization is maintained prior to the removal of the deployment/delivery device.
