ABSTRACT:
A recanalization catheter comprising a very small diameter elongated, flexible tubular member having a distal end at which a tool is mounted for high speed rotation. A flexible drive assembly is located within the tubular member and is connected to the tool. The drive assembly includes a flexible drive shaft mounted within plural spaced bearings to enable the shaft to be rotated at a very high rate of speed from a remotely located motor. The bearings serve to keep the drive shaft centered even as the catheter is bent through a sharp radius of curvature, while also preventing the shaft from going into critical whirl.
