Publication number: 20230225866Abstract: A venous valve prosthetic implant for treatment of venous disease may include an expandable anchoring frame, a valve seat attached to the anchoring frame, a ball retention member attached to the anchoring frame, and a ball disposed within the lumen of the anchoring frame, between the valve seat and the ball retention member. The anchoring frame may include a first end, a second end, and a middle valve portion, where the middle valve portion expands to a smaller diameter than a diameter of either the first end or the second end. The ball may move back and forth within the middle valve portion, between a fully open position and a fully closed position.Type: ApplicationFiled: January 6, 2023Publication date: July 20, 2023Inventors: Albert K.

Publication number: 20210369459Abstract: A prosthetic venous valve includes an expanding anchoring frame, a valve seat at the middle portion of the anchoring frame, a ball disposed within the lumen of the anchoring frame and having an outer diameter, and least one ball retention tether coupled with the ball and the anchoring frame. The ball retention tether includes at least one elastic component or material. The anchoring frame has an upstream end, a downstream end, a middle portion and a lumen extending through the anchoring frame from the upstream end to the downstream end. The ball moves between an open position, in which the ball is located apart from the valve seat, and a closed position, in which the ball is located in contact with or near the valve seat to reduce or prevent backflow of blood through the prosthetic venous valve.Type: ApplicationFiled: June 2, 2021Publication date: December 2, 2021Inventors: Dale L. Ehnes, Teresa Woodson, Christopher Staudenmayer, Austin Walker, Thomas Kramer, Albert K. Chin, Mark Geusen

Patent number: 6157896Abstract: A method for determining the geolocation of an object such as a vehicle traversing the earth's surface or airborne thereabove includes employing a device which is capable of operating autonomously to transmit signals to a selected low earth orbit (LEO) satellite for relay to a receiving station whose position is known, identifying the device and its geolocation, speed, altitude and/or heading. The device includes a microcomputer which operates a Global Positioning System (GPS) receiver for receiving GPS signals to identify the device geolocation and the precise time. A nonvolatile memory on board the device stores LEO satellite ephemeris data, satellite operational and message formatting parameters, LEO satellite visibility footprint data and visibility contour information for the device caused by obstacles which are permanently or temporarily in proximity to the device during deployment and which block transmission of signals between the device and the LEO satellite, depending on relative positions.Type: GrantFiled: December 30, 1996Date of Patent: December 5, 2000Assignee: Southwest Research InstituteInventors: Milford Pike Castles, Austin Walker Boyd, Jr., James Andrew Moryl

Patent number: 6147644Abstract: A system and method for transmitting information to a receiving station via one or more Low Earth Orbit (LEO) satellites includes a device which is capable of operating autonomously to transmit signals to a selected LEO satellite for relay to a receiving station identifying the device and its geolocation including longitude and latitude and/or speed, altitude and heading or course. The device includes a microprocessor which operates a Global Positioning System (GPS) receiver for receiving GPS signals to identify its geolocation and precise time. A nonvolatile memory onboard the device stores LEO satellite ephemeris data, and identification, operational and message formatting information to enable the device to transmit information including voice, data and/or the geolocation of the device to a selected LEO satellite, such as the next visible LEO satellite, for relay to a receiving station.Type: GrantFiled: December 30, 1996Date of Patent: November 14, 2000Assignee: Southwest Research InstituteInventors: Milford Pike Castles, Austin Walker Boyd, Jr., James Andrew Moryl
