Stent with expanding side branch geometry
First Claim
1. A stent assembly having an undeployed state and a deployed state, the assembly comprising:
- a substantially tubular, first stent body defining a lumen positioned within a circumferential plane and having a longitudinal axis therethrough; and
a second stent body, in the undeployed state the second stent body at least partially positioned within the lumen of the first stent body, the first stent body defining a first side branch opening in fluid communication with the lumen, the second stent body comprising a plurality of side branch projecting members, the projecting members defining a second side branch opening in fluid communication with the first side branch opening and the lumen, in the deployed state the projecting members extending through the first side branch opening and forming an oblique angle relative to the longitudinal axis.

Abstract
A stent assembly comprises a substantially tubular, first stent body and a second stent body. In an undeployed state the second stent body is at least partially positioned within the lumen of the first stent body. The first stent body define a first side branch opening in fluid communication with the lumen. The second stent body comprises a plurality of side branch projecting members. The projecting members define a second side branch opening in fluid communication with the first side branch opening and the lumen. In a deployed state the projecting members extend through the first side branch opening and form an oblique angle relative to the longitudinal axis of the first stent body.
