William P. Hajko has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10874787
    Abstract: The invention relates to a degassing vessel and related systems and methods that can remove certain gases such as carbon dioxide from a dialysis system with minimal foaming inside the degassing vessel. The invention further relates to mechanical systems and methods for degassing a dialysate or any fluid used for, during or resulting from dialysis.
    Type: Grant
    Filed: January 31, 2018
    Date of Patent: December 29, 2020
    Assignee: Medtronic, Inc.

  • Patent number: 10420872
    Abstract: The degassing system can include a degassing vessel and can utilize a vacuum pump and a fluid pump located downstream of the degassing vessel to control the pressure within the degassing vessel in order to control the concentration of gases in fluid exiting the degassing system. The degassing system can further comprise sensors in communication with the pumps to control the rate of flow and pressure through the degassing system. The degassing system may be placed in a dialysate flow path to remove dissolved gases including carbon dioxide from the dialysate.

  • Patent number: 10195327
    Abstract: A sensing and storage system for fluid balance during dialysis is provided. The sensing and storage system has flow sensors on either side of a dialyzer in a controlled volume dialysate flow path. The sensors are positioned so that no fluid can be added to or removed from the dialysate flow path between the sensors except for that which is added or removed by action of a control pump. The sensing and storage system can have a fluid removal line for the removal of fluid from the dialysate flow loop.
