First Claim
Patent Images
1. A system for delivering and deploying an implant within a vessel or tubular structure within the body, the implant having a distal end and a proximal end defining a length therebetween and having a diameter, the system comprising:
- at least one string adapted for releasable attachment to the implant;
means for selectively tensioning the implant to selectively adjust at least one of the length or diameter of the implant; and
means for selectively releasing the at least one elongated member from the implant.

Abstract
The present invention provides devices, systems and methods for deploying an implantable device within the body. The invention is particularly suitable for delivering and deploying a stent, graft or stent graft device within a vessel or tubular structure within the body, particularly where the implant site involves two or more interconnecting vessels. The delivery and deployment system utilizes a plurality of strings which are releasably attached to the luminal ends of the implantable device.
