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;
a second stent body, the second stent body being a tubular stent; and
the stent having 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, 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.
