  • Publication number: 20190001136
    Abstract: An implantable stimulator device is disclosed preferably having a lead portion and an electronics module integrated and implantable as a single unit, which can enable trial stimulation to occur in a fully implanted solution for a lengthened or unlimited duration. The side of the housing of the electronic module includes a stylet channel which proceeds through the housing at an angle to the implantable stimulator's long axis and bends to proceed through the lead portion along the long axis. The stylet channel can receive a lead stylet to allow the lead portion and the electronics module to be properly positioned within the patient. Because the proximal end of the lead stylet exits the housing of the electronics module at an angle, it provides a handle to steer the lead portion for proper placement within the spinal column.

  • Patent number: 8790612
    Abstract: A composition comprising: a metal oxide of a first metal ions and second metal ions; an electrically conductive material; and a binder material. The second metal ions have a higher oxidation state than the first metal ions. The presence of the second metal ion increases the number of metal cation vacancies. A method of: dissolving salts of a first metal ion and a second metal ion in water to form a solution; heating the solution to a temperature of about 80-90° C.; and adding a base to the solution to precipitate nanoparticles of a metal oxide of the first metal ion and the second metal ion.
