1. A stent having an undeployed state and a deployed state, the stent comprising:
- a primary tubular body having an outer surface and an inner surface with a wall extending therebetween, the inner surface defining a first lumen having a first longitudinal axis therethrough;
the primary body having at least two side branch portions, each side branch portion comprising a plurality of side branch petals, in the undeployed state the side branch petals comprising a portion of the outer surface of the primary tubular body, in the deployed state the plurality of side branch petals of at least one side branch portion extending out obliquely from the primary tubular body in relation to the first longitudinal axis and defining a second lumen, the first lumen and the second lumen being in fluid communication.

Abstract
A stent has an undeployed state and a deployed state. The stent has a primary body with an outer surface and an inner surface with a wall extending therebetween. The inner surface defines a first lumen having a first longitudinal axis therethrough. The primary body has at least two side branch portions which define secondary lumens having a second longitudinal axis therethrough. The first lumen and the secondary lumen are in fluid communication and in the deployed state one of the side branch portions deploy and the second longitudinal axis forms an oblique angle with the first longitudinal axis.

16. A stent having an undeployed state and a deployed state, the stent comprising:
a primary body having a plurality of interconnected stent members and an outer surface and an inner surface, the inner surface defining a primary lumen having a first longitudinal axis therethrough, adjacent stent members defining a plurality of cell openings in fluid communication with the primary lumen, at least two of the cell openings having a greater area than the adjacent cell openings and having petals which when in the deployed state extend out and form a side branch lumen having a side branch longitudinal axis, the side branch lumen and the primary lumen in fluid communication with one another. - View Dependent Claims (17, 18, 19, 20)
