  • Publication number: 20110009945
    Abstract: A method for deploying a stent delivery system having a blowmolded holder is provided. The stent is configured to expand from a first diameter to a second diameter. The holder is blowmolded to an inner surface of the compressed state. The holder contacts the inner surface and at least portions of side surfaces of the stent, and the holder and the stent have an interference fit therebetween. The deployment method includes delivering the compressed stent placed on the blowmolded holder and the holder into a predetermined deployment side. The deployment method further includes releasing the stent from interference with the holder and expanding the stent from the compressed stent to the expanded stent.
