Disclosed herein are proximally-flaring stents and balloon catheter systems and methods for using the same to restore patency to a side branch and its ostium at a vessel bifurcation, where the side branch can only be approached from the direction of the main artery. The system and methods include a proximally-flaring stent (10) and one or more balloon catheters (250, 400) with inflatable balloons that are able to push a flanged proximal portion (40) of the proximally-flaring stent entirely against the artery walls of the main artery of the side branch so that blood flow is not occluded.
L~invention divulgue des systèmes de stents à évasement proximal et cathéters à ballon, ainsi que des procédés d~utilisation desdits systèmes afin de rétablir la perméabilité d~une branche latérale et de son ostium à une bifurcation vasculaire lorsque la branche latérale ne peut être atteinte que depuis l~artère principale. Le système et les procédés comprennent un stent à évasement proximal (10) et un ou plusieurs cathéters à ballon (250, 400) dont les ballons gonflables peuvent pousser entièrement une partie proximale à bride (40) du stent à évasement proximal contre les parois de l~artère principale donnant accès à la branche latérale, de sorte que la circulation sanguine n~est pas obstruée.
