1. A method for manufacturing a stent delivery system having a holder and at least one stent configured to expand from a first diameter to a second diameter, wherein the second diameter is larger than the first diameter, comprising:

  • compressing the stent to the first diameter, wherein the stent is self-expandable without requiring a balloon;

    inserting the stent into a first tube;

    placing a second tube inside the first tube and inside an inner diameter of the stent, wherein the second tube is airtight;

    applying pressure and heat suitable to the second tube, and blowmolding the second tube against an inner surface of the stent to convert the second tube into the holder having a cylindrical body and a plurality of edges wrapping around at least a portion of the stent such that the stent is expanded to the second diameter by flexing the plurality of edges without substantially expanding the cylindrical body of the holder; and

    separating the first tube from the stent and the blowmolded second tube after cooling down the stent and the blowmolded second tube.
