CROWN STENT ASSEMBLY

摘要

A stent assembly comprises a proximal stent (20) and a distal stent (30) . Each stent has a tubular body defining a stent lumen (35a, 35b) and a circumference. A proximal flap (40) extends from the distal end (45) of the proximal stent and a distal flap (50) extends from the proximal end (55) of the distal stent. Each flap defines only a portion of the circumference. In an expanded state the proximal flap and the distal flap form a side branch support having a side branch support lumen. The side branch support lumen is in fluid communication with the stent lumen and has a longitudinal axis different from that of the stent lumen.
