ABSTRACT:
A catheter, guidewire or other cylindrical object cutting device which includes a base, at least one circular saw blade mounted on a spindle member, and a clamp for manipulating the object to be cut. The at least one circular saw blade is rotatably mounted on the spindle member. The spindle member is free to move vertically and horizontally with respect to the base to thereby control the location, size and depth of the cuts in a cylindrical object disposed adjacent thereto. The clamp is able to hold the object to be cut, as well as rotate it to expose the entire circumference of the object to the saw blade. By releasing the clamp, a pinch roller can advance the object before the clamp is re-engaged to securely hold the object for cutting. Sensors are also provided to enable detection of wear of the saw blade so as to signal needed replacement or adjustment of the saw blade to compensate.
