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 method for treating an aneurysm comprising:

providing a catheter having;

a shaft;

a fixed wire balloon connected to the shaft with a core wire extending distally from a distal tip of the balloon;

a stent with a side opening;

an auxiliary elongated element associated with the shaft and having a distal opening;

and

a guidewire extending through the auxiliary elongated element and exiting through the distal opening;

introducing the catheter into a vessel with an aneurysm;

introducing the guidewire into the aneurysm;

positioning the catheter over the guidewire so that the side opening of the stent is positioned at the aneurysm;

deploying the stent;

removing the catheter leaving the stent and the guidewire in place;

introducing a standard microcatheter over the guidewire;

deploying an embolic device from the microcatheter into the aneurysm.

2. The method of claim 1 wherein the auxiliary elongated element distal opening is disposed adjacent the proximal end of the balloon.

3. The method of claim 2 wherein the auxiliary elongated element has a proximal opening.

4. The method of claim 3 wherein the proximal opening is adapted for rapid exchange of a guidewire.

5. The method of claim 4 wherein the vessel is a cranial vessel.

6. The method of claim 5 wherein the auxiliary element is on the shaft.

7. The method of claim 5 wherein the auxiliary element is in the shaft.

8. The method of claim 1 wherein the auxiliary element is on the shaft.

9. The method of claim 1 wherein the auxiliary element is in the shaft.

10. The method of claim 1 wherein the vessel is a cranial vessel.
