    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.

    Abstract: An inflation device includes a syringe body containing a bore. The bore holds a fluid that is used to inflate a dilation balloon. A plunger assembly slides within the syringe bore and contains a sealing member that forms a fluid tight seal with the syringe body. A shut-off valve is disposed within the distal end of the syringe body. The distal end of the syringe body has a fluid bypass channel fluidically coupled to the aperture of a connector. The shut-off valve has a spring-biased moveable piston with a bypass lumen contained therein, wherein the bypass lumen forms a fluid path between the bore and the fluid bypass channel when the pressure of the fluid is below a threshold value. The fluid path between the bore and the fluid bypass channel is interrupted when the pressure of the fluid is above the threshold value.
