Abstract
An improved catheter atherector for shaving, cutting, and emulsifying accumulated plaque 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 catheter atherector includes an emulsification reduction sphere and extraction wire that rotate and move axially inside the vessel to engage the occlusive material. Emulsified occlusive reduced plaque material and blood only flow in a proximal direction into a catheter lumen. The operation of the device does not substantially disrupt blood pressure within the blood vessel.
