The present invention has to do with a method and system for peritoneal dialysis catheter weighted anchors. The peritoneal dialysis catheter weighted anchors can be inserted and retrieved using standard techniques and available insertion/retrieval systems. The peritoneal dialysis catheter weighted anchors can be attached and secured to all types of PD catheters as an ancillary anchor device.

A fluid extraction implantable system shaped and sized to be implanted in a patient, including: a fluid extraction chamber having a flat and thin shape connected to a draining tube and including at least one external flat surface, wherein the at least one external flat surface is configured to be attached to a tissue surface when a negative pressure is applied on the draining tube, wherein the chamber extracts fluids from the tissue by applying the negative pressure through the flat surface on the attached tissue surface.

A method of performing a peritoneal dialysis treatment includes connecting a disposable unit to a source of water. The disposable unit includes at least a first container holding a sterile concentrate containing an osmotic agent, a second container holding a sterile concentrate containing electrolytes, an empty sterile mixing container, and a tubing set with a pre-attached peritoneal fill/drain line. The method also includes receiving a prescription command by a controller, indicating at least the fill volume and desired final concentration of the osmotic agent to be used for a current fill cycle under said treatment, and pumping a quantity of the concentrated osmotic agent that is at least sufficient to achieve the desired final concentration into the mixing container. The contest of the mixing container are mixed, further diluted or concentrated, and then flowed to a patient.

A method of performing a dialysis treatment includes using a pump and a dialysate supply line to transport peritoneal dialysis fluid, the supply line having a proximal end into which peritoneal dialysis fluid is supplied and from which spend dialysate is withdrawn, and a distal end which is connected to a patient's peritoneal access. The method further includes generating proximal and distal pressure signals using pressure detectors located at both the proximal and distal ends, respectively, of said supply line. During a drain cycle in which spent dialysate is pumped from the patient, the method includes, responsively to the proximal and distal pressure signals, detecting a characteristic of a pressure difference between the distal and proximal ends whose magnitude is determined by a predicted change in dialysate properties, and responsively to the characteristic, generating a signal indicating the change in dialysate properties.

A system includes an implantable device including a pump to pump the fluid from the peritoneum to the bladder via respective catheters, control circuitry, battery and transceiver; a charging and communication system configured to periodically charge the battery and communicate with the implantable device to retrieve data reflective of the patient's health; and monitoring and control software, suitable for use with conventional personal computers, for configuring and controlling operation of the implantable device and charging and communication system. The monitoring and control software allows a treating physician to remotely adjust the volume, time, and frequency with which fluid is pumped from the peritoneal cavity to the bladder based on the data reflective of the patient's health.

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.
