  • METHOD AND DEVICE TO MANAGE FLUID VOLUMES IN THE BODY
    Publication number: 20180353136
    Abstract: A system and method for determining the amount of fluid to be removed from a dialysis patient is disclosed. The system utilizes sensors and a computer. The computer obtains the input parameters from the sensors, along with information added directly by the user, and performs a forward algorithm to determine a recommended change in patient fluid level. As fluid is removed, the effect of the removal on the parameters is detected by the sensors and re-transmitted back to the computer. The computer then performs a backward algorithm to refine the variables used in the forward algorithm and obtain more accurate results. The system and method provide for changing the amount of fluid removed from the patient based on the results of the algorithm and the data received from the sensors.

  • Implantable neurostimulator supporting trial and chronic modes
    Patent number: 10046164
    Abstract: In some examples, a chronic implantable neurostimulator supports trial and chronic modes of operation. In addition, in some examples, the neurostimulator can alternatively include one or more sensors that may or may not function differently in trial and chronic modes. The device may be designed to be used as both a trial neurostimulator and a permanent, or chronic, neurostimulator. A trial neurostimulation period can be used to evaluate the efficacy of the therapy. A percutaneous or implantable trial neurostimulator is used for the trial neurostimulation period. In most cases, the trial period is successful, in which case the trial stimulator is explanted and replaced with a permanent, i.e., “chronic,” implantable stimulator. In accordance with the disclosure, an implantable neurostimulator supports both trial neurostimulation and chronic neurostimulation in the event trial stimulation is successful.
