Patents by Inventor Scott R. Ward

Scott R. Ward has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 5978702
    Abstract: Techniques using one or more drugs and electrical stimulation for treating a neurological disorder, including epilepsy, by means of an implantable signal generator and electrode and an implantable pump and catheter. A sensor is used to detect a seizure or symptoms resulting from the onset of a seizure. A microprocessor algorithm analyzes the output from the sensor in order to regulate the stimulation and drug dosage delivered to the neural tissue.
    Type: Grant
    Filed: October 24, 1997
    Date of Patent: November 2, 1999
    Assignee: Medtronic, Inc.
    Inventors: Scott R. Ward, Mark T. Rise
  • Patent number: 5832932
    Abstract: The present invention is directed to techniques and apparatus for infusing drugs into the brain to treat movement disorders resulting in abnormal motor behavior. The invention employs an implantable pump and a catheter, the catheter having a proximal end coupled to the pump and a discharge portion for placement adjacent a predetermined infusion site in the brain for infusing therapeutic dosages of the one or more drugs into the brain. The pump is operated to discharge a predetermined dosage of the one or more drugs through the discharge portion of the catheter into the infusion site. A sensor may be used in combination with the implantable pump and catheter, whereby the sensor generates a signal relating to the extent of the abnormal motor behavior. The therapeutic dosage is regulated so that the dosage is adjusted in response to an increase in the abnormal behavior to decrease the abnormal motor behavior.
