  • Patent number: 8326436
    Abstract: Systems and methods for improving response of implantable leads to magnetic fields during medical procedures such as magnetic resonance imaging (MRI) are described. In various embodiments, the lead includes an inner conductor that is helically shaped and radially surrounded, at least in part, by one or more high-voltage conductors. The high-voltage conductor can be mechanically and/or electrically coupled, via a coupler, to the shocking coil. The pitch of the inner and/or outer conductor can be varied (e.g., continuously or at certain points) along the length of the lead. In some embodiments, the filar thickness, the pitch, and the mean coil diameter of the inner coil, the high voltage conductor coil, and the shock coil can be configured such that these coils have a desired inductance value when subjected to externally applied electromagnetic energy at radio frequencies commonly generated by MRI scanners (e.g., 40 MHz to 300 MHz).

  • Patent number: 8271097
    Abstract: Various embodiments relating to MRI safe, multi-polar active fixation stimulation leads with co-radial construction are disclosed. Some embodiments, allow the use of the generally smaller diameter co-radially constructed body (coated wires) to construct an active fixation lead, with an extendable/retractable fixation mechanism. Some embodiments use a connector assembly with an inner terminal ring, a terminal pin partially rotatably positioned within the annular inner terminal ring, and one or more resilient C-clips disposed within circumferential recesses. The resilient C-clips mechanically and electrically couple the inner terminal ring and the terminal ring while substantially limiting relative longitudinal translation of the terminal pin.

  • Patent number: 8209033
    Abstract: A system delivers stimulation to volume receptors in the cardiovascular system to induce diuresis in a patient suffering volume overload. The system senses a volume signal indicative of a level of fluid retention in the patient's body and controls the delivery of the stimulation using the volume signal. In various embodiments, the stimulation includes one or more of electrical stimulation, which delivers electrical pulses to the volume receptors, and mechanical stimulation, which physically stretches the volume receptors.

  • Patent number: 7977864
    Abstract: In one method of making an organic electroluminescent device, a transfer layer is solution coated on a donor substrate. The transfer layer includes an amorphous, non-polymeric, organic matrix with a light emitting material disposed in the matrix. The transfer layer is then selectively patterned on a receptor. Examples of patterning methods include laser thermal transfer or thermal head transfer. The method and associated materials can be used to form, for example, organic electroluminescent devices.
