  • Publication number: 20200179583
    Abstract: The invention relates to devices, systems, and methods for performing a precision or personalized Peritoneal Dialysis (PD) therapy session or cycle based on dialysis adequacy measurements in patients undergoing peritoneal dialysis treatment. The settings for the precision peritoneal dialysis therapy session can be obtained using one or more flow sensors and one or more uremic solute sensors that measure the uremic solute concentration and volume of the peritoneal dialysate removed from the patient. The desired dialysis adequacy for a specific patient, group of patients, or class of patients, can then be calculated based on the measured peritoneal dialysate concentration and volume. Using the calculated dialysis adequacy, the system and methods can then set one or more peritoneal dialysis parameters for subsequent cycles or sessions.

  • Publication number: 20200179677
    Abstract: The disclosure is directed to securing electrodes of a medical lead adjacent to a target tissue site. The medical lead may include one or more threaded fixation structures disposed circumferentially about the outer surface of the lead body, or elongated member, that resembles a “screw” or “auger.” During implantation, a clinician may rotate the entire lead to “screw” the lead into the tissue of the patient until electrodes of the lead reside adjacent to a target tissue. In this manner, the threaded fixation structure secures the lead within the patient to resist lead migration and improper therapy and provide a fine adjustment for depth of placement. The threaded fixation structure may be disposed on a portion of the lead proximal to or distal to the electrodes of the lead or over the portion of the lead that includes the electrodes.

  • Patent number: 10583236
    Abstract: A blood based solute monitoring system for measuring at least one blood solute species that has a first recirculation flow path in fluid communication with a dialyzer. The first recirculation flow path is configured to allow a fluid to recirculate through a dialyzer such that the concentration of at least one solute species in the fluid becomes equilibrated to the solute species concentration of the blood in a blood compartment of the dialyzer. The blood solute monitoring system has at least one sensor to measure a fluid characteristic.

  • Publication number: 20200054807
    Abstract: The invention relates to devices, systems, and methods for preforming a precision dialysis therapy session based on an analysis of an effluent from a zirconium phosphate sorbent module during an ammonium removal process. The settings for the precision dialysis therapy session can be obtained by estimating a patient's physiological state, such as BUN level, based on the analysis of the effluent for a particular sorbent module linked to a particular patient.

  • Patent number: 10556104
    Abstract: The disclosure is directed to securing electrodes of a medical lead adjacent to a target tissue site. The medical lead may include at least one adhesive element disposed along a longitudinal outer surface of the lead body to adhere the adjacent tissue to the lead. Adhesive elements may be disposed proximal to, distal to, or in-between the electrodes of the lead. Each adhesive element may be inactive during lead implantation and activated by removing a covering sheath to expose the adhesive elements to moisture in the tissue or presenting an energy, e.g. ultraviolet light, to the adhesive elements. Once active, the adhesive elements secure the lead to surrounding tissue to prevent migration of the electrodes from the target tissue.

  • Publication number: 20200029894
    Abstract: An implantable nerve stimulator is implanted in a patient near a nerve target. The implantable nerve stimulator has a plurality of electrodes through which stimulation is provided to the nerve target. The relative location of the nerve target and the electrodes may be determined by applying stimulation to the nerves via each of the electrodes, determining an effect of the stimulation for each of the electrodes, and mapping a location of the nerve relative to the electrodes based on the effect of the stimulation for each of the electrodes.

  • Patent number: 10537673
    Abstract: The invention relates to systems and methods for optimizing a peritoneal dialysate therapy session based on one or more patient or system parameters obtained from a previous peritoneal dialysis therapy session. The systems and methods include various sensors, flow paths, and processors to adjust a peritoneal dialysis prescription for a subsequent therapy session based on data received during or after one or more previous therapy session. For example, a first peritoneal dialysis therapy session can provide data on patient or system parameters that can adjust the dialysis parameters used to deliver a subsequent peritoneal dialysis therapy session. The method can be computer implemented. The system can also include a peritoneal dialysate generation flow path.
