Crimpable and expandable side branch cell
First Claim
1. A stent having a longitudinal axis and comprising a side branch cell, the side branch cell comprising a plurality of petals including a first petal, each petal comprising a plurality of straight struts and at least one turn, each petal having a central axis, the central axis of the first petal extending in a direction nonparallel to the stent longitudinal axis, wherein at least two of said straight struts of the first petal extend substantially parallel to said stent longitudinal axis.

Abstract
A stent may include a side branch cell comprising a plurality of petals. Each petal may comprise struts and turns, and may have a longitudinal axis oriented at an angle to the stent longitudinal axis. Each petal may include a plurality of straight struts which are substantially parallel to the stent longitudinal axis. Each petal may include at least one appendage which may be oriented substantially parallel to the stent longitudinal axis, and which may remain substantially parallel to the stent longitudinal axis as the stent is deployed. The dimension of the side branch cell about the circumference of the stent may increase more than the dimension of the side branch cell in a stent lengthwise directions as the stent is expanded.

13. A stent comprising a body having a longitudinal axis, the stent having a nominal state and a crimped state, the body defining a plurality of interconnected strut members, a plurality of said interconnected strut members comprising a plurality of petals, the plurality of petals defining a side branch opening, each petal having a longitudinal axis, in at least the nominal state the longitudinal axis of each petal being substantially parallel to the longitudinal axis of the body.
- 14. A stent comprising a body having a longitudinal axis, the stent being expandable from an unexpanded state to an expanded state, the body defining a plurality of interconnected strut members, a plurality of said interconnected strut members comprising a plurality of petals, the plurality of petals defining a side branch opening, each petal having a longitudinal axis, each petal further comprising at least one appendage, each appendage comprising a first strut member, a turn and a second strut member, each appendage having a longitudinal axis, wherein when the stent is in the unexpanded state, the longitudinal axis of each appendage is substantially parallel to the longitudinal axis of the body.
