  • Patent number: 7664551
    Abstract: Systems and methods are provided for modulating the autonomic nervous system by the electrical stimulation of the neuro-muscular system of a patient, and include an implantable electrical system for gastrointestinal stimulation which incorporates a heart rate sensor to indicate the neurovegetative patient condition, to initiate and terminate stimulation at specific locations, and an algorithm to automatically control electrical stimulation frequency, interval, amplitude, or a combination of such parameters for adaptive treatment of obesity, anorexia, other eating disorders, diseases related with the so called “metabolic syndrome” (e.g., impaired glucose tolerance and diabetes type 2, GERD, systemic hypertension, early arterovascular degeneration, early senility, and the like), and disorders related to a pathologic imbalance of the autonomic nervous system.

  • Patent number: 7519433
    Abstract: An implantable lead device and method for implanting the lead, wherein the lead device electrically stimulates tissue within a patient's body and more particularly the lead device stimulates gastrointestinal tissue. The implantable lead may be inserted through the tissue with minimal expansion of the penetration tunnel and attached to the tissue being stimulated with minimal efforts or apparatus. The implantable lead has flexible properties thus minimizing the potential for electrode erosion, maximizing tissue compliance, and minimizing the mechanical stress concentration that may result in fatigue failure in the lead.

  • Patent number: 7292889
    Abstract: Apparatus and method for stimulating neuromuscular tissue in the stomach. The neuromuscular stimulator stimulates the neuromuscular tissue by applying current-controlled electrical pulses. A voltage sensor detects the voltage across the neuromuscular tissue to determine if the voltage meets a predetermined voltage threshold. A control circuit adjusts the current-controlled pulse if the voltage is found to meet the voltage threshold, such that the voltage does not exceed the voltage threshold. A voltage-controlled pulse may also be applied to the tissue. A current sensor would then detect whether the current on the neuromuscular tissue meets a predetermined current threshold, and a control circuit adjusts the voltage-controlled pulse such that the current does not exceed the current threshold. A real time clock may be provided which supplies data corresponding to the time of day during the treatment period.
