Abstract
A stent delivery balloon catheter system includes a pair of retainers which are anchored to the catheter to hold the stent against the balloon until the stent is to be deployed. Each retainer is made of filaments which are woven together to form a braided tube shaped structure. Further, each retainer has one end which is anchored to the catheter while the free end of the retainer overlaps a respective end of the stent. Upon inflation of the balloon for deployment of the stent, the balloon also urges against each retainer. This causes the woven tube structure of the retainer to expand, and thereby shorten. As the retainers shorten, they also withdrawn from the stent, and thereby release the stent for deployment.
