A method and apparatus for the treatment of thrombosis, venous insufficiency, and the like, and in particular to an Automated Compulsory Blood Extraction System (ACBES) configured to provide an efficient and safe means for the measured extraction of blood utilizing a device providing, in effect, an artificial leech, but without the infection, control, care, and other limitations associated with the medicinal leech. The preferred embodiment of the present invention utilizes recent micro technological advances to provide a micro mechanical device which mimics and improves upon the bloodletting properties of the medicinal leech utilizing a micro mechanical valve, micropump, and micro sensor arraignment cooperating with a tertiary jaw array having teeth situated thereon. The preferred embodiment of the present invention contemplates an extraction device which may have a head size of one centimeter or less, and which may be utilized in number about the affected area of the patient to provide controlled, precision, pulsed blood extraction via vacuum induction, supplying a controlled dosage of anticoagulant, histamine anesthetic, or the like. Alternative embodiments of the present invention include an independent, single needle, stationary design configured primarily for emergency use, a multi-needle piston design, a large extraction area array design including concentric needles of adjustable depth, and a deep extraction needle design.
