Embodiment Construction

[0040] The present invention is a balloon expandable stent for bifurcation and opening lesions. The term bifurcation in this patent includes all types of bifurcation lesions (sites) and lesions (sites) adjacent to bifurcations in blood vessels, or all types of opening lesions (including aortic ostia and juncture sites).

[0041] The stent has a tubular structure and includes a balloon-expandable body capable of supporting a main blood vessel. It has a portion that expands out corresponding to the expansion of the main body to at least partially enter the side branch vessel and support the side branch opening, the portion being deployed without the need for an additional dilatation balloon. Deployment can be achieved with additional balloons, if desired.

[0042] An example of a bifurcated stent design 10 is shown in FIG. 1 as a two-dimensional uncrimped flat shape. Other structural features of the stent 10 are shown in FIG. 2 , while FIG. 3 shows the same stent 10 mounted on...

Abstract

The present invention provides methods and devices for placement of a stent in a bifurcation or ostial lesion. The stent comprises a main body and a flaring portion. The main body is designed to expand and support a main vessel while the flaring portion deploys at least partially in response to expansion of the main body and is designed to open into and support a side branch or bifurcation ostium area. The stent may also comprise a therapeutic agent which can be delivered to a blood vessel.
