SYSTEMS OF DEPLOYMENT OF ENDOLUMINAL DEVICES

摘要

A removable sleeve (210) extends around an expandable stent graft (300) to constrain the expandable stent graft toward a collapsed configuration. The sleeve is held together by a coupling member (230) to constrain the expandable device toward the collapsed configuration for endoluminal delivery to a vascular treatment site. The sleeve is openable by displacing the coupling member away from the sleeve to allow outward expansion of the expandable device toward an expanded configuration. The sleeve is separate from the expandable device so as to be removable from the treatment site after deployment of the expandable device.
