Abstract

A catheter system for treating lesions is provided. The system is suitable for treatment of bifurcation lesions, has a low profile and provides substantially predictable translational and rotational positioning. In one embodiment, the system includes a fixed wire balloon catheter and a partially attached guidewire lumen, wherein the guidewire lumen is attached to the catheter at a crotch point. The location of the crotch point is predetermined so as to provide substantially predictable positioning. Several embodiments of the system are described for various types of lesions and vessel configurations.

Claims

1. A catheter system comprising:

a main elongated element having a main elongated element proximal end and a main elongated element distal end;

a balloon positioned at said main elongated element distal end, the balloon comprising a balloon proximal end and a balloon distal end and a wire attached to said balloon distal end;

a core wire positioned internally along a portion of said main elongated element proximal to said balloon, and further positioned externally alongside said balloon, said core wire further attached to said wire at said balloon distal end.

2. The catheter system of claim 1, further comprising an auxiliary elongated element positioned internally along at least a portion of said main elongated element, said auxiliary elongated element having a distal exit point at said main elongated element distal end.

3. The catheter system of claim 2, wherein said distal exit point is positioned at a rotational distance from said external core wire.

4. The catheter system of claim 3, wherein said rotational distance is approximately 180 degrees.

5. The catheter system of claim 2, wherein said auxiliary elongated element further comprises an exit point at a portion of said main elongated element, said exit point for rapid exchange of guidewires.

6. The catheter system of claim 2, further comprising a guidewire positioned through said auxiliary elongated element.

7. The catheter system of claim 1, further comprising multiple core wires.
