Abstract: The invention relates to an infusate frame for use in dialysis. The infusate frame includes one or more openings cut-out of a rigid support frame. The one or more openings are sized and shaped complementary to one or more infusate containers, ensuring that only a single infusate container can occupy a specific opening.

Abstract: The invention relates to an infusate holder for use in dialysis. The infusate holder can include one or more interior compartments for holding infusate containers or infusates. The interior compartments are aligned to cooperate with fluid connectors of a dialysis system, ensuring that the proper infusates are added to the dialysis system at a proper location.

Abstract: Introducers for implanting a lead having a fixation element distal to an electrode include a window, electrode, or conductive member alignable with the electrode of the lead white maintaining the fixation element in a retracted configuration. The window, electrode or conductive member of the introducer provide a mechanism for applying test stimulation signals to determine whether the lead is properly positioned in a patient without deploying the fixation element.

Abstract: A device includes (i) a housing defining an interior, wherein the interior has a blood compartment, a plasma compartment, and a fluid compartment; (ii) a first filter disposed in the interior of the housing, and (iii) a second filter disposed in the interior of the housing. The first filter separates at least a portion of the blood compartment from at least a portion of the plasma compartment. The first filter is configured to allow plasma components, but not cell components, of blood to pass through the first filter from the blood compartment to the plasma compartment. The second filter separates at least a portion of the plasma compartment from at least a portion of the fluid compartment. The second filter is configured to allow fluid and small molecules, but not larger components, to pass through the second filter from the plasma compartment to the fluid compartment. The device may include a sorbent in the plasma compartment to remove or reduce the concentration of selected components of the plasma.

Abstract: An implantable medical elongated member extends between a proximal end configured to be coupled to a medical device and a distal end. The implantable elongated member includes one or more fixation elements coupled to at least a middle portion and/or a proximal portion of the elongated member in order to substantially fix a position of the elongated member to tissue at one or more intermediate points between the proximal end and the distal end of the elongated member.

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.

Abstract: A sorbent based monitoring system for measuring the solute concentration of at least one component of a fluid. The system has a sorbent regeneration system for regeneration of the fluid and has a sorbent cartridge that has at least one material layer. The fluid is conveyed through the sorbent cartridge and contacts at least one sensor after having contacted at least one material layer.

Abstract: Systems and methods for multiple analyte analysis are provided. In one embodiment, a method includes determining concentrations of first and second analytes in a sample. The first and second analytes may be, for example, glucose and hydroxybutyrate. In this form, an indication related to the measured concentration of hydroxybutyrate is provided in response to determining that the concentration of hydroxybutyrate is above a predetermined value. In a further aspect of this form, a quantitative indication representative of the measured glucose concentration is automatically provided regardless of the value of the measured glucose concentration. In another embodiment, a system includes a meter configured to interact with a test element to assess first and second analytes in a sample. Further embodiments, forms, objects, features, advantages, aspects, and benefits shall become apparent from the description and drawings.

Abstract: Systems and methods for controlling fluid movement and volumes of fluid between a subject and a controlled compliant flow path. The controlled compliant flow path has a means for selectively metering in and metering out fluid from the controlled compliant flow path. An extracorporeal flow path is in fluid communication with the controlled compliant flow path across a semi-permeable membrane where the extracorporeal flow path has a first terminal end and a second terminal end.

Abstract: Techniques and systems for determining a head position of a patient and controlling delivery of electrical stimulation to a target stimulation site based on the determined head position are described. In some examples, movement of the head of the patient may result in movement of a lead, through which the electrical stimulation may be delivered, relative to the target stimulation site. Thus, controlling delivery of the electrical stimulation based on the head position may improve the efficiency and efficacy of the electrical stimulation therapy.

Abstract: Systems and methods are provided for determining an estimated risk of arrhythmia during or after dialysis based on changes in serum potassium concentration of a patient and an amount of fluid removed from the patient during dialysis. The systems and methods allow for a determination of a risk that arrhythmia will occur due to the changes in potassium and fluid volume of a patient during dialysis, and for optimizing a dialysis prescription in order to minimize the risk of arrhythmia.

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.
