  • Patent number: 10758659
    Abstract: The invention relates to systems and methods for optimizing a peritoneal dialysate prescription based on one or more fluid characteristics sensed from a filtrate removed from a patient. The systems and methods include sensors, flow paths, and processors to adjust a peritoneal dialysate prescription and deliver peritoneal dialysis therapy to a patient based on the adjusted prescription. The method can include the steps of removing fluid from a peritoneal cavity of a patient; sampling one or more characteristics of the removed fluid; and adjusting a peritoneal dialysate prescription based on the one or more characteristics of the removed fluid. The system can include a peritoneal dialysate effluent line; at least one concentrate source fluidly connectable to the peritoneal dialysate flow path; and at least one sensor positioned in the peritoneal dialysate effluent line.

  • Patent number: 10744253
    Abstract: The invention relates to systems and methods for adjusting one or more dialysis parameters for delivering a peritoneal dialysis cycle to a patient based on patient or system parameters. The systems and methods include various sensors, flow paths, and processors to adjust the dialysis parameters used to deliver peritoneal dialysis therapy, for a specific peritoneal dialysis cycle. For example, a first peritoneal dialysis cycle can provide data on patient or system parameters that can be used to adjust the dialysis parameters used to deliver a subsequent peritoneal dialysis cycle. One or more peritoneal dialysis cycles are contained in a particular peritoneal dialysis therapy session. Patient parameters can include patient blood pressure; volume of fluid removed; patient goal; blood solute level; effluent solute level; effluent temperature; effluent color or clarity; patient posture; tidal volume remaining in patient; and intraperitoneal pressure.

  • Patent number: 10743779
    Abstract: A system and method for controlling a monitoring mode or treatment mode of an implantable medical device based on the detection of an external signal. The system and related method allow for more frequent monitoring of medical parameters at times where more frequent monitoring is necessary, such as during or after a dialysis session, with less frequent monitoring at other times, allowing for a more efficient medical device. The invention also allows for the frequency or mode of treatment by the implantable medical device, or the transmission of data from the implantable medical device to be controlled based on the external signal.

  • 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.
