| 摘要 |
<p>The present invention relates to a delivery system for an intraluminal thin film medical device particularly well suited for occlusion of an aneurysm, vessel side branch or dissection of a body lumen or duct, such as an artery or vein. The delivery system has an outer sheath attached along the distal end of a relatively long and flexible tubular shaft. The outer sheath is capable of constraining the thin film medical device in a longitudinally stretched position, and subsequently being retracted relative to the flexible tubular shaft to release the thin film medical device from the constrained longitudinally stretched position. The delivery system may additionally have a secondary sheath substantially coaxial too, and slideably engaged within, the outer sheath. The secondary sheath is capable of restraining a self-expanding support structure in a radially constrained position, and subsequently being retracted to release the self-expanding support structure from the radially constrained position. The delivery system also comprises an inner lumen substantially coaxial to the outer sheath and incorporated into the flexible tubular shaft.</p> |
