  • Patent number: 11273243
    Abstract: A system includes a dialyzer having a blood side and a dialysate side, a first extracorporeal circuit including one or more first fluid connectors structurally configured to connect the blood side of the dialyzer to the vascular system of a kidney patient, and a second extracorporeal circuit including one or more second fluid connectors structurally configured to connect the dialysate side of the dialyzer to the vascular system of a healthy animal. The present teachings may thus include a system where hemodialysis is performed using a healthy animal (e.g., a person with normal kidney function) to help remove harmful solutes from, and provide helpful solutes to, a kidney patient. In this manner, the healthy animal is “virtually donating” its kidney function to the kidney patient.

  • Patent number: 11253429
    Abstract: An alignment assembly for a cartridge interface of a drug delivery device is disclosed. The assembly optionally includes a coupling for opening fluid communication between the cartridge and the delivery device. For example, the coupling optionally includes a cannula insertable through a septum of the cartridge. The assembly may include a guide for positioning the cartridge and/or an access channel thereof within a first precision of a loaded position. The assembly optionally includes a cartridge engagement fitting (for example a gripping expander sleeve collar) attached to the coupling. Optionally when the cartridge is engaged to the fitting, the coupling is retained in connection with the access channel to within a second precision. The second precision is optionally higher than the first precision. In some embodiments one or more compliant supports movably retain the fitting oriented to engage the cartridge when the access channel is in the loaded position.

  • Patent number: 11246973
    Abstract: A drainage bag is provided for a thermal control unit adapted to deliver temperature-controlled liquid to a patient in order to control the patient's temperature. The drainage bag is used to hold and transport the liquid when the liquid inside the thermal control unit is changed. The drainage bag includes a bottom layer, a top layer sealed thereto, and a float secured to the top layer that is positioned adjacent an opening in the top layer. As the liquid from the thermal control unit drains into the opening in the top layer, the liquid lifts the float and the float lifts the top layer of the bag. The bag thereby expands its volume to accommodate the liquid from the thermal control unit. The bag may further be designed to be carried without sealing the opening and without spilling the liquid. A method for using the bag is also disclosed.

  • Patent number: 11197951
    Abstract: An apparatus and method are disclosed for detecting the disconnection of a vascular access device such as a needle, cannula or catheter from a blood vessel or vascular graft segment. A pair of electrodes is placed in direct contact with fluid or blood in fluid communication with the vascular segment. In one embodiment, the electrodes are incorporated into a pair of connectors connecting arterial and venous catheters to arterial and venous tubes leading to and from an extracorporeal blood flow apparatus. Wires leading from the electrodes to a detecting circuit can be incorporated into a pair of double lumen arterial and venous tubes connecting the blood flow apparatus to the blood vessel or vascular graft. The detecting circuit is configured to provide a low-voltage alternating current signal to the electrodes to measure the electrical resistance between the electrodes, minimizing both the duration and amount of current being delivered.
