Spectranetics Laser wire. This independently movable wire is coupled to a pulsed laser. It actively crosses chronic total occlusions and then serves as a “rail” to support the delivery of angioplasty devices.

CardioGenesis PMR laser delivery system. These photographs of the working end of the catheter depict the 1.75-mm lens coupled to a 400-μm optical fiber. The nitinol petal array retards full transmural advancement of the device.

4. Fig 3
PercuSurge embolization containment system. (A) A inch GuardWire is advanced beyond the diseased vein graft segment. The distal tip of the GuardWire carries an elastomeric low pressure occlusion balloon. The GuardWire is delivered through a standard guiding catheter. (B) The distal occlusion balloon is inflated and angioplasty and stenting of the vein graft is completed. (C) With the distal occlusion balloon still inflated, the angioplasty device is removed over the GuardWire and an aspiration catheter (Export catheter) is advanced and particulate debris removed before deflation of the distal occlusion balloon. The GuardWire is then deflated and removed.
