A method is disclosed comprising providing a self-expandable stent having a polymeric component. The stent is exposed to a relative humidity of 20% to 100% (RH) or a plasticizing agent is applied to the polymeric component. The diameter of the stent is reduced. The stent having a reduced diameter is inserted in a constraining sheath such that the sheath constrains the stent in a reduced diameter, such that removal of the stent from the sheath causes the stent to self-expand to a greater diameter.
