Abstract: The invention relates to systems and methods for sensing fluid characteristics of peritoneal dialysate infused into and removed from a patient during treatment. The systems and methods include sensors, processors, and flow paths for determining patient health based on the fluid characteristics of the peritoneal dialysate. The system can be a peritoneal dialysis cycler which can include an infusion line; an effluent line; at least one pump positioned in the infusion and/or effluent line; and at least one sensor fluidly connected to the effluent line. The sensor can be at least one of a flow sensor, an ion selective electrode, a pH sensor, a pressure sensor, a refractive index sensor, and a temperature sensor. The method can include infusing peritoneal dialysate through an infusion line; removing peritoneal dialysate through an effluent line; and determining at least one fluid characteristic of the peritoneal dialysate in the effluent line.

Abstract: An apparatus and method for replenishing urease in a sorbent cartridge for use in sorbent dialysis. The system is configured to allow insertion of a urease pouch, injection of a urease solution, or addition of a urease cartridge, into a dialysis cabinet containing a dialysis flow loop. The urease can be dissolved and the resulting urease solution added to the sorbent cartridge in the flow loop to replenish the urease within the sorbent cartridge. The sorbent cartridge can also comprise other, rechargeable, sorbent materials for removing toxins other than urea from spent dialysate.

Abstract: Techniques for modeling therapy fields for therapy delivered by medical devices are described. Each therapy field model is based on a set of therapy parameters and represents where therapy will propagate from the therapy system delivering therapy according to the set of therapy parameters. Therapy field models may be useful in guiding the modification of therapy parameters. As one example, a processor compares an algorithmic model of a therapy field to a reference therapy field and adjusts at least one therapy parameter based on the comparison. As another example, a processor adjusts at least one therapy parameter to increase an operating efficiency of the therapy system while substantially maintaining the modeled therapy field.

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.

Abstract: Parallel modules for in-line recharging of sorbent materials using alternate duty cycles for a sorbent cartridge. The sorbent cartridge can have two or more modules contained therein having connectors connecting each of the modules. One or more of the modules can be reusable and the sorbent materials therein can be recharged.

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.

Abstract: A portable dialysis cabinet for use in dialysis. The portable dialysis cabinet can have a size and weight that facilitates easy movement of the cabinet from one location to another with relative ease. The portable dialysis cabinet can have additional features necessary to facilitate portability, such as wheels and a handle. In general, the portable dialysis cabinet can contain all the necessary components for performing a dialysis session.

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.
