1. A stent, the stent comprising:
- a first stent body, the first stent body being a rolled stent having a first end and a second end, the first stent body comprising a plurality of circumferential bands and a plurality of connectors, each circumferential band comprising a plurality of struts engaged one to another by turns, wherein some of the turns in a circumferential band are peaks and others are troughs, adjacent circumferential bands being engaged by a plurality of connectors separated one from another by a single turn;
a second stent body, the second stent body being a tubular stent, the second stent comprising a plurality of circumferential bands and a plurality of connectors, each circumferential band comprising a plurality of struts engaged one to another by turns, wherein some of the turns in a circumferential band are peaks and others are troughs, adjacent circumferential bands being engaged by a plurality of connectors separated one from another by at least two turns; and
the stent having a deployed state, the second stent body at least partially disposed within the first stent body when the stent is in the deployed state, the first end of the first stent body overlapping the second end of the first stent body for a first overlap length when the stent is in the deployed state.

Abstract
A stent has a first stent body and a second stent body. The first stent body is a rolled stent having a first end and a second end and the second stent body is a tubular stent. The stent has a deployed state, the stent being within a body lumen in the deployed state. The second stent body at least partially disposed within the first stent body when the stent is in the deployed state so that the first end of the first stent body overlaps the second end of the first stent body for a first overlap length.
