SYSTEMS AND METHODS FOR TREATING A VESSEL USING FOCUSED FORCE
First Claim
1. A method for treating a lesion in a vessel, the method comprising:
- providing a device having a main elongated element, a balloon at a distal end of the device, an auxiliary elongated element wherein a distal end of the auxiliary elongated element is proximal to the balloon, and a wire attached to the device and positioned alongside the balloon and on an opposite side of the balloon as the auxiliary elongated element and a distal connecting element at a distal end of the balloon;
inserting a tracking guidewire into the vessel;
backloading the tracking guidewire into the distal connecting element;
advancing the device over the tracking guidewire until the distal end of the device is adjacent to the lesion;
advancing a second guidewire through the auxiliary elongated element; and
inflating the balloon so as to push at least the attached wire and the tracking guidewire against a lesion in the vessel, said pushed attached wire and tracking guidewire each pushing against different sides of the lesion.

Abstract
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.
