    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: In a mechanical test system, a method of compensating for acceleration induced load error in a load sensor in a mechanical communication with a component comprises measuring an acceleration of the component to obtain an acceleration measurement. A load sensor measures a force applied by the mechanical test system to a test sample in substantially a same direction of the acceleration to obtain a force measurement. The force measurement is modified with a transfer function that includes at least one of a gain correction and a phase correction to compensate for an error value in the force measurement attributed to movement of at least the load sensor when the force is applied to the test sample.
