1. An intraluminal stent deployment system, comprising:
- a catheter;
an expandable stent disposed about a portion of the catheter;
at least one anchoring device attached to the catheter and having a proximal portion disposed distal of a midpoint of the stent, wherein the anchoring device deploys to contact a body vessel before the stent is expanded to a fully expanded configuration in the vessel.

Abstract
An intraluminal stent delivery and deployment system and a method of delivering and deploying an intraluminal stent are described. The stent delivery and deployment system includes a catheter, an expandable stent disposed about a portion of the catheter, and at least one anchoring device attached to the catheter. The anchoring device has a proximal portion disposed distal of a midpoint of the stent. The anchoring device is deployed and engages a body vessel before the stent is expanded to a fully expanded configuration, thereby anchoring at least the catheter to the body vessel during the expansion of the stent.

13. A method of deploying an intraluminal stent, comprising:
-
providing a deployment assembly comprising;
a catheter;
an expandable stent disposed about a portion of the catheter;
at least one anchoring device attached to the catheter;
positioning the deployment assembly in a body vessel at a treatment site;
deploying the anchoring device to engage the body vessel, thereby anchoring the catheter to the body vessel;
expanding the stent, the stent reaching a fully expanded configuration after the deploying of the anchoring device;
undeploying the anchoring device after the stent has reached the fully expanded configuration; and
removing the catheter and the anchoring device from the body vessel, leaving the stent in the vessel in the fully expanded configuration. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
