Patents by Inventor Douglas P. Perrin

Douglas P. Perrin 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: 20230211045
    Abstract: An implantable, autonomously growing medical device is disclosed. The device may have an outer, braided outer element that holds an inner core. Degradation and/or softening of the inner core permits the outer element to elongate, allowing the device to grow with surrounding tissue. The growth profile of the medical device can be controlled by altering the shape/material/cure conditions of the inner core, as well as the geometry of the out element.

  • Publication number: 20230039350
    Abstract: Method and devices for viewing one or more valve leaflets via a viewer. In some embodiments the viewer includes a body having a first end and a second end opposite the first end, the first end being closed and having a transparent viewing window, the second end arranged to be attached to an aorta or a pulmonary artery, and one or more ports arranged to provide fluid access to an internal portion of the viewer to pressurize the one or more leaflets. A diameter of the viewing window is larger than an outer diameter of the second end. An outer diameter of the first end of the body is larger than an outer diameter of the second end. The body is a tubular body.

  • Patent number: 7255192
    Abstract: A self-actuating robot or vehicle tether capable of moving itself, remaining free while traversing around obstacles, and free itself is disclosed. In a preferred embodiment of the invention, a valve is mounted to the tether or robot. An inflow conduit attached to or in the tether is connected to the valve. A fluid flows through the tether and the valve is opened and closed to create a waterhammer effect in the inflow conduit. The forces created on the tether from the waterhammer effect result in motion of the tether and in freeing of the tether from obstructions. Closing and opening the valve further creates pressure changes in the tether, thereby causing momentary dimensional changes in the tether. In an alternative embodiment, a plurality of valves are placed along the tether. Pulsing of the plurality of valves while a fluid flows through the tether results in the tether effectively moving itself.
