Abstract
An atherectomy catheter includes a rotary cutting knife that is driven from the distal (nose) or side (circumference) direction. The catheter collects plaque shavings in a hollow collection chamber mounted in between the rotary cutting knife and the main catheter tubing. In contrast to prior art designs, which utilized nose mounted plaque collection chambers, the present design is able to store a substantially larger volume of removed plaque, thus increasing the length of time and amount of plaque removal that can be accomplished before the catheter must be removed from the body and cleaned. This decreases medical procedure time, allows for more complete and careful plaque removal, and reduces the burden on the patient and physician.
