A method and apparatus for administering percutaneous electrical therapy to a recipient. The apparatus can include an electrical coupler having a coupling member configured to be removably positioned at least proximate to a percutaneous probe. The coupling member can be coupleable to a source of therapeutic electrical signals via a therapeutic signal transmission link to transmit the therapeutic electrical signals to the recipient. The apparatus can further include a status signal transmission link at least proximate to the therapeutic signal transmission link and coupleable to a status signal emitter. The status signal transmission link can be at least tamper-resistant and/or tamper-evident, and can be configured to transmit a status signal having a first characteristic value when the status signal transmission link is in a first condition and a second characteristic value when the status signal transmission link has been altered from a first condition to a second condition.

Assignee:
Heartstream, Inc. - Seattle WA
International Classification:
A61B 504
US Classification:
128696
Abstract:
The present invention is an apparatus and method for detecting differential mode signals in an environment where differential mode signals co-exist, and might be corrupted by, common mode signals. The most basic apparatus of the present invention essentially comprises first and second input leads through which both differential mode and common mode signals are input; a first amplifier block having a gain that is substantially one; and at least an inverting node and a non-inverting node connected to the first and second input leads. The output of the amplifier block is fed back to the input of the non-inverting node of the amplifier block in a manner to increase differential mode impedance while maintaining a low common mode impedance. Various embodiments of the basic presently claimed circuitry provides for additional methods of monitoring the level of common-mode signal introduced to the apparatus and other fault detection functions.

John Harris - Bellevue WA, US
International Classification:
A61B 5/0476
US Classification:
600544
Abstract:
Medical device systems and methods for operating medical device systems conserve energy by efficiently managing computational demands of the systems. Signals from a subject are processed and analyzed and an estimate of a propensity for a subject to have a neurological event is determined. Based on the results of the analysis and the estimate, further analysis may be performed and the estimate may be refined. Succeeding cycles of signal measurement and analysis are scheduled depending on the results of the analysis and the estimate. The schedule may be varied temporally or with regard to the types and intensities of analyses performed.
