Patents by Inventor Hoai (Kevin) Nguyen

Hoai (Kevin) Nguyen 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: 11950794
    Abstract: Retrieval of material from vessel lumens can be improved by electrically enhancing attachment of the material to the thrombectomy system. The system can include a catheter having a distal portion configured to be positioned adjacent to a thrombus in a blood vessel, an electrode disposed at the distal portion of the catheter, and an interventional element configured to be delivered through a lumen of the catheter. The electrode and the interventional element are each configured to be electrically coupled to an extracorporeal power supply.
    Type: Grant
    Filed: October 11, 2021
    Date of Patent: April 9, 2024
    Assignee: COVIDIEN LP
    Inventors: Hoai (Kevin) Nguyen, Gaurav Girdhar, Andyanhdzung Huynh

  • Patent number: 11612430
    Abstract: Retrieval of material from vessel lumens can be improved by electrically enhancing attachment of the material to the thrombectomy system. The system can include a catheter having a distal portion configured to be positioned adjacent to a thrombus in a blood vessel, an electrode disposed at the distal portion of the catheter, and an interventional element configured to be delivered through a lumen of the catheter. The electrode and the interventional element are each configured to be electrically coupled to an extracorporeal current generator. Delivery of current to the interventional element can be gradually ramped up during initialization to improve patient comfort and safety.
