Deployment system for an expandable device
First Claim
Patent Images
1. A deployment system for a self-expanding endoluminal device comprising:
- a catheter with at least one lumen;
a retractable sheath adapted to surround at least a portion of the endoluminal device which constrains the device in an introductory profile;
a deployment line configured to pull with the sheath to effectuate device deployment so that the sheath retracts from the device along with the deployment line retraction upon actuation;
a deployment line lumen which encases the majority of the length of the deployment line and allows deployment line movement; and
wherein said deployment line lumen is configured to prevent rotation of the catheter relative to the deployment line during deployment line actuation.

Abstract
The present invention is directed to a deployment system for a self-expanding endoluminal device. The deployment system includes a confining sheath placed around a compacted endoluminal device so that upon deployment the sheath is transitioned into an internal deployment line housed within the catheter. The deployment system is configured to prevent rotation of the catheter relative to the deployment line during deployment line actuation.

21. A deployment system for a self-expanding endoluminal device comprising:
-
a catheter shaft with at least one lumen;
a retractable sheath at least partially enclosing the catheter shaft; and
a deployment line configured to pull with the retractable sheath so that rotation of the catheter shaft relative to the deployment line is prevented. - View Dependent Claims (22, 23, 24, 26)
