Abstract:
A system for maintaining a patient lumen at a bifurcation of an anatomic canal comprising:two slanted-end stents each of which comprises a radially expanded mesh structure substantially forming a cylinder having a longitudinal axis, a back end defined by a plane substantially perpendicular to the axis, and a slanted front end defined by a plane oriented relative to the axis at an angle less than 90 degrees;one V-shaped-end stent comprising a radially expandable mesh structure substantially forming a cylinder having a longitudinal axis, a back end defined by a plane substantially perpendicular to the axis, and a front end defined by the intersection of two planes intersected to form a V-shaped front end as viewed radially;in which the V-shaped-end stent is implantable in a common branch of a bifurcation of the canal and oriented so that the V-shaped front end extends into the bifurcation; andin which the slanted-end stents are separately implantable in secondary branches of the bifurcation and are oriented so that each slanted front end extends into the bifurcation in abutting relation to the V-shaped front end, thereby providing reinforcing coverage to substantially all affected area of the bifurcation.
