  • Ex vivo and in vivo systems for evaluating hemostatic patches, sealants, adhesives on solid organs
    Patent number: 11885735
    Abstract: The present is directed to systems for ex vivo testing performance of a hemostatic or sealing product attached to an animal organ and fully covering a cored channel in said organ, comprising: a pressure sensor positioned proximate to said hemostatic or sealing product in said cored channel; a monitoring or recording device configured to receive pressure readings from said pressure sensor; and a pressurized fluid source connected to said cored channel and configured to supply said pressurized fluid into said cored channel under constant or variable pressure. The present invention is also directed to methods of use for such systems.
    Type: Grant

  • Systems, devices and methods for consistently and uniformly measuring the diameters of sutures
    Patent number: 11454485
    Abstract: A system for measuring the diameter of a suture includes a test bench, a first suture clamping assembly slidably mounted to the test bench, and a second suture clamping assembly fixed to the test bench. The system includes a suture diameter gauge slidably mounted to the test bench and located between the first and second suture clamping assemblies for obtaining suture diameter measurements for a suture secured to the clamping assemblies. The system has a rotation assembly coupled with the first and second suture clamping assemblies for simultaneously rotating the first and second suture clamping assemblies on an axis between a first position and a second position that defines a right angle with the first position. The system includes a suture tensioning assembly for applying tension to a suture secured to the first and second suture clamping assemblies as the suture is rotated on its axis.
