STENT MIT ABZWEIGUNG UND FLEXIBLEN SEITENTEILEN

摘要

A bifurcated stent for maintaining the patency of body lumens such as coronary arteries comprising a main stent portion and a smaller diameter side stent portion having an end secured to the length of the main stent portion. The side stent portion is preferably flexible so as to be readily insertable into a side branch of a body lumen. For delivery, the bifurcated stent is mounted on a first and second catheter with the first catheter extending through the length of the main stent portion and the second catheter extending through a part of the main stent portion and then through the side stent portion. Preferably, the end of the side stent portion is secured to the main stent portion with multiple sutures around the perimeter of the end of the side stent portion. The invention also comprises the method of implanting the bifurcated stent.
