Abstract
Devices and methods are provided for fatigue testing a medical device, e.g., an annuloplasty ring, using a cam rotatably mounted relative to a base and one or more sets of mounts on the base for securing opposite ends of the medical device. For example, each set of mounts may include a stationary mount on the base, a sliding mount on the base adjacent the cam, and a follower slidably mounted to the sliding mount that contacts the cam such that the follower reciprocates along a horizontal axis as the cam rotates about a vertical axis. The follower and stationary mount include connectors to secure opposite ends, respectively, of a medical device such that rotation of the cam causes the follower to reciprocate and apply tensile and/or compressive loads to fatigue test the medical device.
