1. A stent comprising:
- a main body defining a plurality of cells, the main body including opposite ends;
an end structure adapted to be flared relative to the main body, the end structure being located adjacent at least one of the ends of the main body; and
the end structure including predefined bend locations for facilitating flaring the end structure relative to the main body.

14. A stent comprising:
-
a main body defining a plurality of cells, the main body having opposite ends;
a plurality of end struts adapted to be flared relative to the main body, the end struts being integrally connected with at least one of the ends of the main body; and
the end struts including regions of reduced radial wall thickness for facilitating flaring the end struts relative to the main body. - View Dependent Claims (15, 16)

18. A stent comprising:
-
a main body including a plurality of support members defining a plurality of open cells, the support members extending about a circumference of the main body and each defining an undulating pattern having a plurality of peaks and valleys;
a plurality of end struts adapted to be flared relative to the main body, the end struts being connected to at least some of the peaks of the main body; and
the end struts defining notches for facilitating flaring the end struts relative to the main body. - View Dependent Claims (19, 20, 21, 22)

23. A method for implanting a stent at a junction between first and second vessels, the stent including a main body and an end structure adapted to be flared relative to the main body, the stent also including predefined bend locations for facilitating flaring the end structure relative to the main body, the method comprising:
-
positioning the stent such that the main body is located within the first vessel, the end structure extends into the second vessel, and the predefined bend locations are located adjacent the junction between the first and second vessels;
radially expanding the main body into contact with an interior surface of the first vessel; and
flaring the end structure relative to the main body such that the end portion generally conforms with an interior surface of the second vessel, the end structure being flared by bending the stent at the predefined bend locations while maintaining the predefined bend locations adjacent the junction between the first and second vessels.

24. A stent comprising:
-
a main body defining a plurality of cells, the main body having opposite ends;
a plurality of end struts adapted to be flared relative to the main body; and
the end struts having lengths, and the end struts being thinned along their lengths relative to the main body for facilitating flaring the end struts relative to the main body.
