Containment sleeve and deployment device
First Claim
1. A delivery device for delivering a stent or a stent-graft into a patient, including a catheter provided with a distal region for holding thereon a stent or a stent-graft on the distal region;
- the catheter including an internal lumen therewithin and a distal end;
a containment sheath being provided with a distal portion and a proximal portion, wherein the distal portion of the containment sheath is everted over the distal region of the catheter to contain the stent or the stent-graft, wherein the proximal portion of the containment sheath located in the internal lumen, and wherein the distal portion of the containment sheath is pulled over the distal end and through the internal lumen of the catheter during delivery of the stent or the stent-graft.

Abstract
A deployment device for deploying stents, stent-grafts and other implants into a patient includes a catheter (112) with a containment sheath (116). Held onto the catheter (112) is a stent-graft structure (120). The containment sheath (116) extends over the entirety of the stent graft section (122) so as to constrain it in its entirety on the catheter (112), until the sheath (116) is removed. The containment sheath (116) extends from the distal position (126) of the stent graft section (122) to the tip (114) and then into the central lumen (128) of the catheter (112). It may extend throughout the lumen (128) to the proximal end of the deployment device (10), in other words to the external manipulation section of the delivery device (10). The sheath (116) is withdrawn by pulling towards the external manipulation section of the delivery device. As this is effected, the containment sheath (116) is pulled over the end (114) of the catheter and into the central lumen (128) of the catheter (112). As this occurs the containment sheath (116) is in effect withdrawn into the catheter (112), thereby releasing the stent-graft section (122) gradually. Continued pulling will gradually pull the entirety of the containment sheath (116) into the open end of the catheter (112), thereby releasing the entirety of the stent-graft section (122).
