Method for manufacturing a stent delivery system
First Claim
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.

Abstract
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 is provided. The manufacturing method includes compressing the stent to the first diameter, inserting the stent into a first tube, placing a second tube inside the first tube and inside an inner diameter of the stent. The second tube is airtight. The manufacturing method also includes applying pressure and heat suitable to the second tube, thereby blowmolding the second tube against the stent.
