Abstract: An apparatus and method for performing biopsies in-vivo using magnetically labeled nanoparticles is disclosed. One embodiment of the apparatus is called a magnetic needle. When used in a biopsy, one embodiment of the present invention collects diseased cells in-vivo which have been tagged with magnetic nanoparticles coated with receptors for specific diseased cells.

Abstract: An apparatus and methods for the prevention or minimization of lower extremity venous thrombosis comprising an impedance component disposed at the proximal end of the lower extremity and a compression component disposed at the distal end of the lower extremity. The proximal impedance component is activated to impede return venous blood flow, preferably on the femoral vein, until blood volume in the lower extremity is maximized. In response to deactivation of the proximal compression component, the distal compression component is activated to assist return venous blood flow. The apparatus and methods enhance blood circulation in the lower extremity by increasing washout of stagnant blood from the lower extremity, particularly from the venous sinuses and valve cusps where thrombosis tends to form.

Abstract: Devices for electrosurgery by means of oxy-hydro combustion and methods for use of such devices in electrosurgical procedures. Provided are devices for combustion of oxygen and hydrogen, or other hydrocarbon fuels, wherein oxygen and hydrogen may be generated by electrolysis or oxygen and hydrogen, or other hydrocarbon fuels, may be supplied, such devices including an ignition source and an adjustable and translatable sheath for controlling such reactions. Also provided is a detachable and positionable sheath for controlling reactions and minimizing tissue damage with conventional electrosurgery devices.
