SYSTEM AND METHOD FOR MANIPULATING A GUIDEWIRE THROUGH A CATHETER
First Claim
1. A method of manipulating a guidewire comprising the steps of:
- providing a catheter including a lumen disposed there through;
providing a guidewire disposed through the lumen, wherein said guidewire is movable with respect to the catheter;
providing a steering tool;
mounting the steering tool over the catheter such that the catheter is disposed between the steering tool and the guidewire;
tightening the steering tool to apply sufficient radial pressure to pinch the catheter into gripping engagement with the guidewire to manipulate the catheter and the guidewire together.

Abstract
A system and method for manipulating a guidewire includes a steering tool, a catheter, and a guidewire. The steering tool includes a bore disposed there through. The catheter is disposed within the ore of the steering tool. The guidewire is disposed within a lumen of the catheter such that the catheter is disposed between the steering tool and the guidewire. The steering tool includes a main body and nut. The main body includes a collet portion including circumferentially spaced jaw separated by longitudinally extending slots. The nut is threaded over the collet to close the jaw with sufficient radical pressure to deform the catheter such that the guidewire may be manipulated with the catheter disposed between the guidewire an the steering tool.

11. A system for delivering a device to a treatment region within a vessel comprising:
-
a steering tool including a bore disposed there through; a catheter disposed within the bore of the steering tool, the catheter including a lumen disposed there through; and a guidewire disposed through the lumen such that the catheter is disposed between the steering tool and the guidewire, wherein the guidewire is movable with respect to the catheter; wherein the steering tool is capable of being tightened to apply sufficient radial pressure to pinch the catheter into gripping engagement with the guidewire to manipulate the catheter and guidewire together. - View Dependent Claims (15, 16, 17, 18, 20)
