  • Patent number: 10837892
    Abstract: Systems, methods, and devices are provided for testing a drug eluting prosthesis. A drug eluting prosthesis is placed within a conduit that is coupled at one end to a first conduit frame and at a second end to a second conduit frame. The first conduit frame is coupled to the second conduit frame using a movable shaft, such that the first conduit frame and the second conduit frame can move relative to each other. When the first conduit frame and the second conduit frame are moved relative to each other, they expose the conduit and the drug eluting prosthesis to compressive or tensile forces. While the drug eluting prosthesis is being exposed to compressive or tensile forces, a fluid flow is provided through the conduit to test the particle shed rate of the drug eluting prosthesis.

    Abstract: The invention generally relates to systems and methods for stress testing to failure tubular mesh devices, specifically, one or more stents or mesh grid tubes. A radial compression method of stress to fatigue is developed by placing a tubular medical implant within a lower than normal compliance test vessel. A radial expansion method of stress to fatigue is developed by placing higher than normal compliance tubes within a tubular medical implant. A method for radial expansion and radial compression is conducted by placing a higher than normal compliance tube through the mesh device and the placing the tube and device within a lower than normal compliance test vessel. Each method is tested on a tester that operates by delivering pulsatile flow with varying pressures, frequencies and testing parameters. Fracture of the test subject is visualized by high speed camera.

  • Patent number: 10307915
    Abstract: An inspection method of a suction nozzle. Air flow rates that flow in multiple reference pipes that have different sectional areas are measured. A proportionality factor between air flow rates and sectional areas of the reference pipes is calculated based on the measured air flow rates of the multiple reference pipes, and the sectional areas of the multiple reference pipes. An air flow rate in a suction nozzle that is an inspection target is measured. The sectional area of the suction nozzle is calculated based on the air flow rate of the suction nozzle and the calculated proportionality factor. The sectional area of the suction nozzle calculated in this manner is substantially fixed even when the pressure of air supplied from an air source fluctuates. The sectional area of the suction nozzle is proportional to the air flow rate that flows in an inner portion of the suction nozzle.

    Abstract: Exemplary embodiments of the present invention provide a differential pressure transducer that comprises first and second diaphragms of different configurations, i.e., different diameters and/or thicknesses. The pressure transducer provides more versatility over prior art designs as the diaphragms can be of different configurations yet still maintain substantially similar back pressures. Therefore, the errors commonly associated with back pressures are eliminated because the back pressures from the diaphragms ultimately cancel out in the sensor's differential pressure measurement.

  • Patent number: 9021864
    Abstract: A mechanism is provided for sensing molecules. A twin-nanopore probe includes a first channel and a second channel. A first pressure-controlled reservoir is connected to the first channel to generate a positive pressure. A second pressure-controlled reservoir is connected to the second channel to generate a negative pressure. A container includes ionic solvent with molecules, and a tip of the twin-nanopore probe is submerged in the container of the ionic fluid with the molecules. The first channel, the second channel, the first pressure-controlled reservoir, and the second pressure-controlled reservoir are filled with the ionic fluid. The first pressure-controlled reservoir drives the ionic fluid out of the first channel and the second pressure-controlled reservoir draws in the ionic fluid with the molecules and solvent through the second channel. A change in magnitude of ionic current through the second nanopore of twin-nanopore probe is detected when molecules pass through the second nanopore.

  • Publication number: 20150040644
    Abstract: A fatigue testing system provides simultaneous cycle testing for a plurality of prosthetic devices under simulated physiological loading conditions. A plurality of sample holders containing test samples of prosthetic devices is positioned between a distribution chamber and a return fluid chamber to form an integrated test chamber. A reciprocating linear drive motor operates a rolling bellows diaphragm to cyclically pressurize fluid within the test chamber and drive the pressurized fluid through the prosthetic devices being tested. The test chamber defines a return flow conduit in fluid communication with each of the sample holders, the return fluid chamber, and the distribution chamber. Compliance chambers and throttle valves associated with each of the sample holders regulate the pressure gradient and back pressure across the prosthetic devices being tested.
