摘要:
In at least one embodiment, a stent comprises a side branch structure having an inner crown, an outer crown and a plurality of side branch connectors, each side branch connector connecting between the inner crown and the outer crown. Upon expansion of the side branch structure, the inner crown displaces outwardly in a stent radial direction. The entire inner crown moves out of the area defined by the generally cylindrical framework of the main stent body. Upon the outward displacement of the inner crown, the side branch connectors may reorient and also extend out of the area defined by the generally cylindrical framework of the main stent body. The inner crown may further comprise a plurality of outwardly deployable petals. Desirably, side branch expansion forces placed on the inner crown will first cause the inner crown to displace outwardly, then cause the petals to deploy outwardly.
