Guide wire control catheters for crossing occlusions and related methods of use |
| abstract |
A wire control catheter for aligning and guiding a guide wire through a lesion in a vessel is provided. The wire control catheter includes a shaft having a guide wire lumen and a control wire lumen. A control wire passes through the control wire lumen and is used in combination with an articulation structure to deflect or curve a distal tip portion of the catheter. The distal catheter shaft may include a centering device for centering the catheter within the vessel. The distal catheter shaft also may include a pre-dilation balloon for dilating the lesion prior to performing angioplasty or other treatment on the lesion. Additionally, a sliding sheath catheter may be used to provide additional support to the guide wire. The sliding sheath catheter is sized to fit within the guide wire lumen of the control catheter and to allow the guide wire to pass through it. A method of treatment of a blood vessel includes inserting a guide wire into the blood vessel and advancing a control catheter over the guide wire until the distal tip of catheter is near the occlusion in the blood vessel. The tip of the catheter then is deflected via a control wire and an articulation structure. The guide wire is then advanced across the occlusion. The control catheter also may be advanced across the occlusion simultaneously with the guide wire or subsequent to the guide wire crossing. Prior to crossing the occlusion, the wire control catheter may be centered using a centering device. Subsequent to crossing the occlusion, the occlusion may be pre-dilated with a pre-dilation balloon of the wire control catheter. |
