Patent ID: 6896694

Claim:
A device for disobstruction of arteries having obstructions in proximity to primary and secondary branches or bifurcations of the artery, comprising: a balloon catheter having a balloon; and a stent covering the balloon, the stent having a wall formed by a flexible metallic wire mesh which is constricted prior to inflation of the balloon and expanded upon inflation of the balloon, the stent having two ends, one end adhered to the balloon when the balloon is not inflated, and the other end circumferentially non-attached to and radially spaced from the balloon when the balloon is not inflated, the other end configured to be selectively, partially expanded when the balloon is not inflated to enable passage of a proximal end of a metallic wire previously introduced into the secondary branch of the artery, the wire providing access to the secondary branch, and adapted for guiding one of a second balloon and a second stent unto the secondary branch.
