  • Patent number: 10076283
    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.

  • Patent number: 10071323
    Abstract: This disclosure generally relates to at least one reusable module of a sorbent cartridge in a sorbent dialysis system and a method of using the same. One of the drawbacks of a conventional sorbent dialysis system is the high cost. In one aspect of the invention, the sorbent cartridge contains at least one module for optionally recharging sorbent materials in-line with an optional bypass and conduits for the sorbent cartridge. The sorbent cartridge can have two or more modules that are connected to one another through connectors. The modules can be reusable and the sorbent materials contained in the modules can be recharged.

  • 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.

  • Patent number: 9993639
    Abstract: This disclosure describes techniques for securing an elongated member, such as a medical lead, within a tissue of a patient. In particular, suction is applied from a vacuum to a vacuum cavity located proximate to a distal end of the lead to draw in tissue from the target therapy delivery site to the vacuum cavity. A fixation element is coupled to the tissue within the vacuum cavity to fix the lead to the target therapy delivery site. The fixation techniques of this disclosure secure the medical lead to the tissue of the patient to prevent the medical lead from migrating away from the target tissue location.
