  • Patent number: 11129566
    Abstract: An improved pressure sensory threshold testing instrument comprised of a filamentous testing element (132) mounted on a head member (102) that is pivotally attached to a handle member (100) with a nonelectrical power assist pivot mechanism. The power assist pivot mechanism aids in actively biasing the head member (102) into either an open, testing position or a closed, storage position. The power assist mechanism and geometry resist accidental opening that could expose and damage the filament. The design facilitates one-handed operation with no change in grasp needed throughout the whole process of retrieval, testing, and storage. This singular grasp allows for increased ease and efficiency of the testing procedure. The configuration speeds the testing process while protecting the filament more securely in an instrument that is portable in a pocket. The design also minimizes the potentially threatening appearance of this type of medical testing device.

  • Patent number: 9050473
    Abstract: 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. As movement of the selected group of electrodes occurs, current redistribution amongst the various electrode contacts takes place. 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.

  • Publication number: 20140296194
    Abstract: Methods of reducing or abolishing neuropathic pain in humans and animals are discussed. In some examples administration of the apoptosis inhibitor taurours-odeoxycholic acid (TUDCA), greatly reduced both neuronal loss and the increase in glia, and partially reversed spinal nerve ligation (SNL)-induced mechanical hypersensitivity. Among RVM neurons, serotonergic (5-HT) neurons decreased by 35% ipsilateral to SNL. In some examples, the density of 5-HT immunoreactive varicosities in the superficial dorsal horn of the spinal cord was lower ipsilateral to SNL. The RVM 5-HT neurons that remained after SNL appeared to facilitate nociception. When rats that had undergone SNL were treated with the 5-HT neurotoxin, 5,7-dihydroxytryptamine (5,7-DHT), mechanical withdrawal thresholds increased significantly. In some examples nerve injury induces death of antinociceptive RVM neurons which can be reduced or abolished by TUDCA.

  • Patent number: 8444571
    Abstract: A system and method is disclosed for measuring muscle reflexes (e.g., a bulbocavernosus reflex) as a tool for identifying/diagnosing dysfunctions (e.g., spinal cord abnormalities, bladder voiding dysfunction, and sexual organ dysfunction) non-invasively by using mechanical stimulation. The system and method includes a probe having a predetermined patient contacting portion, wherein when the contacting portion is moved into contact with a particular area of the patient (e.g., the patient's genitals), the contact induces a muscle reflex. The probe detects the pressure resulting from the contacting portion being abruptly and forcibly brought into contact with the particular area. Such detection is used to electronically initiate capture of electrical responses from a plurality of electrodes placed on the patient's skin in proximity to the particular area. Such electrical responses are processed to determine characteristics of the patient's reflexes of one or more muscles adjacent to the electrodes.

    Abstract: Disclosed herein are a pure silver device and a method for diagnosing and treating pain on human body. The pure silver device comprises an elongated handle, a head having both a hammer head and a comb opposed to each other, a panel, and an outwardly extending protrusion on the bottom end of the handle. The pure silver device is used to diagnose and treat pain by finding out pressure pain points on both abdominal area, at which root of pain is located, and a symptomatic area of the human body and then by releasing the pressure pain points by tapping, pressing, rubbing, combing or combining the foregoing. Owing to the highest thermal and electrical conductivity of silver, the pure silver device produces amazingly better stimulation of the pressure pain points. Therefore, the pure silver device is more effectively used for diagnosing and treating pain than other devices made out of any other material, even sterling silver and magnetic material.
