  • Systems for testing valves
    Patent number: 10350069
    Abstract: A chamber assembly for testing a valve includes a proximal chamber portion that defines a proximal interior space, and a distal chamber portion that defines a distal interior space. The distal interior space includes a gas space. When a liquid is inserted into the proximal and distal chambers there is an interface between the liquid and a gas in the gas space. A valve holder is disposed adjacent to the proximal interior space and the distal interior space. The valve holder is configured to receive the valve in a bore of the valve holder. A shortest distance between a center of the valve when in the bore and the interface is at least about 45 mm.

  • Specimen conditioning and imaging system
    Patent number: 9753104
    Abstract: A conditioning system includes a sample chamber capable of receiving a specimen as well as first and second specimen-holding fixtures positioned within the sample chamber and configured to apply mechanical stimulation to a specimen held by the fixtures. The system has at least one port capable of providing a fluid to the sample chamber. The chamber is sized and shaped so that it can be inserted into an imaging device which can record images of a specimen held by the fixtures.
