## Abstract

The present invention provides a portable therapeutic device for treatment of dyslipidemia, hyperviscosaemia, diabetic neuropathy, and peripheral artery disease, using rotating Static Magnetic Fields (rSMF). The device comprises a two part plastic housing with a handle and a designated treatment area, a DC motor with microcontroller and a cylindrically shaped magnet roller, which comprises magnets tightly fitted into a stainless steel sleeve capped with two bearing shafts protruded on each end. The magnet roller assembly rotates freely inside the housing with little clearance at assigned low frequency in line with the DC motor axis driven by magnetic torque from magnetic couplings, which include equally sized quad-pole magnet plates on each coupling base. The rSMF-based device produces an inhomogeneous surface intensity of 4000-7000 Gauss from its dual-pole or quad-pole parallel circuitry for an effective treatment regimen of the indicated disorders.
