Abstract

The present invention provides methods for fabricating a stent using a preheating stage. The inventors have found a fabrication methods that result in the same and/or better product quality stent using a single step process performed at a temperature of below 65° C., more preferably below 60° C., most preferably below 55° C. Stent fabrication under such reduced temperature conditions reduces the exposure of the stent to adverse temperature conditions, thereby enabling the greater retention of the polymer's memory. Further, upon expansion, the stent does not contract to a smaller diameter but instead remains at a constant diameter or increases to a larger diameter.
