CRIMPABLE AND EXPANDABLE SIDE BRANCH CELL

摘要

A stent (10) may include a side branch cell (30) comprising a plurality of petals (40) . Each petal may comprise struts (36) and turns (38) , and may have a longitudinal axis (42) oriented at an angle to the stent longitudinal axis (18) . 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 (70) 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.
