20090275920 | SYSTEMS AND METHODS FOR TREATING A VESSEL USING FOCUSED FORCE - Systems and methods for treating a vessel include devices having a main elongated element with a balloon at its distal end, an auxiliary elongated element wherein a distal end of the auxiliary elongated element is proximal to the balloon, and a core wire having a internal core wire portion and an external core wire portion, wherein the external core wire portion is external to the balloon. In some embodiments, a distal connecting element is attached to the distal end of the balloon. In some embodiments, the distal connecting element is positioned at a rotational distance from the auxiliary elongated element. In some embodiments, the balloon is a fixed wire balloon. Inflation of the balloon causes guidewires positioned within the device and external core wires to be pushed up against the lesion, providing a focused force for cracking the lesion. | 11-05-2009 |
