Patent number: 6909917Abstract: An implantable pulse generator includes a current steering capability that allows a clinician or patient to quickly determine a desired electrode stimulation pattern, including which electrodes of a group of electrodes within an electrode array should receive a stimulation current, including the amplitude, width and pulse repetition rate of such current. Movement of the selected group of electrodes is facilitated through the use of remotely generated directional signals, generated by a pointing device, such as a joystick.

The redistribution of stimulus amplitudes utilizes re-normalization of amplitudes so that the perceptual level remains fairly constant. This prevents the resulting paresthesia from falling below the perceptual threshold or above the comfort threshold.Type: GrantFiled: August 15, 2003Date of Patent: June 21, 2005Assignee: Advanced Bionics CorporationInventors: Carla Mann Woods, David K.

An EMS generator is connected to the belt through the transducer. As the user exercises in a first direction, increasing stimulation is applied to the subject muscles. As the user moves the rotatable component in the opposite direction, decreasing stimulation is applied to the user. In an alternative embodiment, the belt has at least one pair of electrodes connected to a common adjustment control so that as the voltage increases to one of the electrodes, it decreases to the other electrode of the pair, and vice versa. A toggle switch makes possible the selection of a particular pair.Type: GrantFiled: January 21, 2003Date of Patent: April 5, 2005Inventor: Arthur F. Hurtado

Publication number: 20040267168Abstract: The method and apparatus for balancing the electric potential of a human body takes advantage of pressing to arouse the force and latent power of self-treatment by electric current of the human body. The method mainly is done by pressing the abdomen and the buttocks to make the human body generate regular respiration whereby positive and negative ions in the nature are absorbed and delivered by the blood and the nerve system for circulation to make complement and get a balanced effect with the positive and negative ions in the cell tissues in the nerve system of the human body. The apparatus is provided mainly on a base with massage mechanisms, by pressing the vital points on the abdomen and the buttocks periodically for predetermined times with the massage mechanisms, and by the images shown, the user can totally pay attention to the area where the electric current flows through to promote balancing of the positive and negative ions to get the effect of removing diseases and making good health.Type: ApplicationFiled: June 27, 2003Publication date: December 30, 2004Inventor: Kuo-Wei Feng

Publication number: 20040088036Abstract: A device, which is preferably disc shaped, has two primary layers. A first layer has one side, which is the lower side in use, for adhering to a patient's skin surface, a second, upper layer on the underside of which electrical circuitry is printed or affixed so that the electrical circuitry is sandwiched between the layers. The device can be made in several sizes to accommodate patient size and location of the acupuncture point to be stimulated. Two distinct forms of the device are presented: a single use and a reusable device for. In the single use device, the first, lower layer is preferably a foam with non-conductive adhesive on both sides: the bottom side for adhering to the skin and the top side for adhering to the upper polyester disc. The holes through this lower foam layer include, preferably, eight holes spaced concentrically about one central hole in the middle of the lower foam layer.Type: ApplicationFiled: October 31, 2002Publication date: May 6, 2004Inventor: Bruce R.
