Patents by Inventor David T. Aldridge

David T. Aldridge 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).

  • Publication number: 20240099760
    Abstract: A device and method for creating an arteriovenous (AV) fistula includes a proximal base having a distal diagonal end surface and a distal tip connected to the proximal base and movable relative to the proximal base. The distal tip has a proximal diagonal end surface. A heating assembly, including an energized heating element, is disposed one of the distal diagonal end surface and the proximal diagonal end surface. A passive heating assembly is disposed on the mating diagonal end surface. The distal diagonal end surface and the proximal diagonal end surface are adapted to contact opposing sides of a tissue portion to create a fistula. The angle of the proximal diagonal end surface matches the angle of the distal diagonal end surface, so that the two surfaces match one another during deployment.

  • Patent number: 11937769
    Abstract: A method including detecting a modular surgical device within bounds of a surgical operating room, connecting the modular surgical device to a surgical hub, connecting the surgical hub to a cloud-based system, transmitting surgical data associated with a surgical procedure being performed in the surgical operating room from the modular surgical device to the surgical hub, and transmitting the surgical data from the surgical hub to the cloud-based system.

  • Patent number: 11937821
    Abstract: A power controller device and system allows verification, monitoring, and control of an arteriovenous (AV) fistula creation catheter which comprises a main housing having a power supply, an embedded electronic controller and a user interface display, and which is configured to allow connection to an intravascular catheter. When activated, the device verifies that a valid catheter is connected, downloads stored manufacturing calibration data from the catheter, and provides a user interface to allow initiation of AV fistula creation. Once creation of the AV fistula is initiated, the device provides closed loop control of the catheter heating element and provides a means of monitoring the catheter temperature and tip position to a prescribed parameter to automate the arteriovenous fistula creation procedure.

  • Publication number: 20240074757
    Abstract: A method of operating a catheter assembly including monitoring a gap feedback signal indicative of a distance between a first tissue contact surface and a second tissue contact surface. Producing, via a user interface of the catheter assembly, a graphical depiction of the first tissue contact surface and the second tissue contact surface spaced apart from the first tissue contact surface by the distance. Producing, via the user interface of the catheter assembly, a gap distance warning when the gap feedback signal indicates that the distance is outside of a target gap range.
