Rotoblation

Rotoblation uses a tiny cutting tool guided into the area of the blockage in a blood vessel by a catheter procedure. Rotoblation is similar to other atherectomy procedures, but instead of using a tiny blade to shave away the obstruction, the device has a specialized tip that bores into the obstruction. The debris created by this technique is much smaller than with other atherectomy devices and can be cleared naturally from the bloodstream as waste. In contrast to directional atherectomy, the rotational device may be preferred when arteriograms of the affected artery or arteries reveal one or more of the following characteristics:

  • A longer segment of artery is affected

  • The entry to an artery is affected

  • Several sites in the same vessel are affected hardened or dense calcium deposits in the lesions reduce the likelihood that other techniques will be effective
