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.

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.

Abstract: A novel system and apparatus for testing surgical fastening devices in an ex-vivo body wall wound closure simulation device is disclosed. The system is particularly useful with simulating abdominal wall wound closure. The system has a body wall curvature approximator device, a tissue fixation system, and a tissue support and tensioner device. The system provides for anatomically correct presentation and tensioning on body wall tissue specimens for ex-vivo wound closure simulation. The system may also be used for other anatomic tissue specimens in addition to body walls.
