1. A system for treating vasculature at a repair site, comprising:
- a first treatment component;
a first sheath having the first treatment component and configured to receive a subsequent treatment component after the first sheath is placed within the vasculature and the first treatment component is deployed, the first sheath having an inferior end and a length sufficient to extend to a repair site within the vasculature; and
a loading capsule configured to receive a subsequent treatment component, wherein the loading capsule includes a superior terminal end that is configured to mate with the inferior end of the first sheath.

Abstract
The present invention embodies delivery systems and methods of packing an initial endovascular graft components for delivery that achieve a smaller delivery profile and reduce redundancy. Delivery systems and methods for packing the initial endovascular graft components for delivery facilitate a reduced delivery profile while allowing reliable positioning of the components before deployment.
