Patents by Inventor Jon Armstrong

Jon Armstrong 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: 12324894
    Abstract: An improved method and device are provided for forming and/or maintaining a percutaneous access pathway. The device generally comprises an access pathway and attachment device. The provided assembly substantially reduces the possibility of iatrogenic infection while accessing and/or re-accessing a body space.
    Type: Grant

    Date of Patent: June 10, 2025
    Assignee: Critical Innovations LLC
    Inventors: Ross I. Donaldson, Oliver Buchanan, Tim Fisher, Jon Armstrong, John Cambridge
  • Publication number: 20240376206
    Abstract: Disclosed are methods for treating extensive-stage small-cell lung cancer (ES-SCLC) with an antibody that inhibits PD1/PD-L1 activity in combination with etoposide and a platinum-based therapeutic agent.

  • Publication number: 20240350128
    Abstract: Systems, methods and compositions relating to delivering synthetic polymer formulations to the body are described, which can be used by a range of medical personnel including those with minimal experience and training. Under some embodiments, the present invention relates to systems and devices for delivering polymer formulations to a body cavity (e.g. peritoneal cavity) to reduce or stop bleeding. Under some embodiments, an initial percutaneous access pathway is first formed using a delivery device with a probe and needle mechanism that automatically stops the advance of the device upon insertion into a body cavity or space, thus minimizing user error and improving patient safety. The hollow probe then allows transmission of polymer, mixed with gas and/or additional substances, from a holding chamber or canister to flow through the device and hollow probe into the patient's anatomic cavity or space of interest, stopping expansion when the device senses the appropriate pressure.
