  • Lead electrode for use in an MRI-safe implantable medical device
    Publication number: 20050222642
    Abstract: An implantable stimulation system comprises a stimulator for generating electrical stimulation and a conductive stimulation lead having a proximal end electrically coupled to the stimulator, wherein at least a first component of the impedance looking into the stimulator is substantially matched to the impedance of the stimulation lead. At least one distal stimulation electrode is positioned proximate the distal end of the stimulation lead.

  • Telemetry antenna for an implantable medical device
    Publication number: 20050203584
    Abstract: A telemetry antenna for an implantable medical device includes one or more portions having a non-linear configuration. In some embodiments, the non-linear configuration provides an antenna having a greater antenna length than the linear lengthwise dimension of the antenna structure. In some embodiments, the non-linear configuration is a serpentine pattern.

  • Energy shunt for producing an MRI-safe implantable medical device
    Publication number: 20050070972
    Abstract: A neurostimulation system is configured for implantation into a patient's body and comprises a neurostimulator, a conductive stimulation lead having a first proximal end and a first distal end, at least one distal electrode electrically coupled proximate the first distal end, and a lead extension having a second proximal end electrically coupled to the neurostimulator and having a second distal end electrically coupled to the first proximal end. A shunt is electrically coupled to the first proximal end for diverting RF energy from the lead.
