Abstract: An improved plaque extractor for shaving, scooping, cutting, and emulsifying accumulated plaque from blood vessels into fine particles, and removing the particles from blood vessel walls without cutting or permanently stretching the walls, and without substantially blocking the blood flow through the vessel during plaque removal operation. The plaque extractor includes an extractor guide and an internal auger, in which both are rotating and moving axially inside the vessel to engage the occlusive material. The operation of the device does not substantially disrupt blood pressure within the blood vessel.
