  • Patent number: 11166676
    Abstract: This medical device measures blood flow rate through the renal artery after a kidney transplant in real time. The device utilizes a force sensing resistor (FSR) to detect the amount of blood and the given blood pressure at any instantaneous point in time. The FSR wraps around the renal artery after transplantation and should remain connected for five to seven days for optimal kidney blood flow and kidney functioning detection. This will be achieved by measuring the flow rate, estimating blood pressure, and beats per minute this device should alert doctors if irregular kidney function should occur for fast and immediate surgical or bedside intervention. Our goal is to detect post-transplant kidney rejection in real-time. The device is biocompatible and sterile, easily removed from the renal artery, and smaller than 5 mm in diameter.

  • Patent number: 10039199
    Abstract: An adapter has two conductors each with a U-shaped bend forming upper longer legs and lower shorter legs. The conductors face each other with the longer legs linearly aligned with each other and the shorter legs aligned with each other, thereby forming a first gap between the longer legs and a second gap between the shorter legs. The first gap is substantially smaller than the second gap, so that an electrical package can be placed across the first gap to contact the two upper longer legs, while the two shorter legs are spaced further apart to span a larger gap between conductors of a connector. Thus, the adapter enables the electrical package to be connected to conductors having a gap that is larger than the electrical package.

  • Patent number: 9808607
    Abstract: In one aspect, an implantable shunt system is disclosed that, in one example implementation, includes a resilient member and a connected fluid regulating device. The fluid regulating device selectively permits fluid flow through an opening valve of an implantable shunt according to an adjustable opening pressure. The opening pressure is proportional to an amount of tension on the resilient member. One or more tension sensors that are connected to the resilient member measure an amount of tension on the resilient member. The tension sensors generate tension data that corresponds to the measured amount of tension. The system further includes a communication unit with a transmitting unit that transmits the measured data over a communication link. The system also includes a reading unit that receives the transmitted tension data over the communication link. The reading unit includes a connector that electrically connects the reading unit to the transmission unit.
