  • External presentation of electrical stimulation parameters
    Publication number: 20070055318
    Abstract: An external indicator device presents parameters associated with stimulation therapy generated by a pulse generator, which may be associated with an external or implantable stimulation device. In this manner, the external indicator device enables a user to visualize stimulation parameters without actually delivering stimulation therapy to a patient via implanted electrodes. The electrical stimulation parameters may include electrical amplitude levels, pulse widths, pulse rates, electrode combinations, and electrode polarities for stimulation generated by the pulse generator.

  • Passive flow control devices for implantable pumps
    Patent number: 6979315
    Abstract: An implantable drug delivery device is provided with a passive flow control device is provided in the form of a valve which may assume two flow states. Flow control is achieved by duty cycling the valve using a control module which generates appropriate signals in response to an input telemetry signal corresponding to a desired flow rate. In another embodiment, a passively controlled bolus delivery device is provided to deliver a bolus of drug in addition to normal dosage.
