Stent for ostial lesions and vascular bifurcations
First Claim
1. A stent for vascular ostial and bifurcation lesions constituted by a tubular body formed by a metal framework which, when subjected to the action of an expansion balloon is capable of exerting tension in a direction of its diametrical expansion until outer surfaces press against an endothelium of an application vascular conduit, defining an endovascular positioning which maintains or increases the clearance of said conduit, comprising:
- said tubular body constituted by a succession of sections a framework of which is festoon shaped;
each festoon shaped section being comprised by rows of entrances and projections;
said sections and said rows being engaged by means of engaging bridges;
at least one end row comprises means affording expansive bending capacity; and
said expansive bending forming a portion to be attached to the ostial or bifurcation lesion.

Abstract
A stent for ostial lesions and vascular bifurcations has a tubular body comprised by a succession of sections of skeletal members. In one or both end rows of the tubular body, there are expansive bending devices comprising sectional weakenings and open extremities. In the case of the end row, by a proper expander balloon, expansive bending of longitudinal branches of the end row may be produced. Bending is produced due to sectional weakenings. Open extremities allow producing the expansion in a way such as the flourishing of a flower bloom. Under such conditions, bending of the end row makes possible the adequate coverage of the ostial or bifurcation lesion affecting wall of the application vascular conduit.
