Abstract

A crimping device for crimping a medical device includes a housing assembly, an iris assembly including crimping members, a handle assembly, and a rotating body operably coupled to the handle and to the crimping members such that rotation of the handle causes rotation of the rotating body to drive the crimping members toward or away from each other to close or open the iris assembly. A sizing key is configured to be coupled to the rotating body. When the sizing key is not coupled to the rotating body, the rotating body has a first range of rotation corresponding to a first minimum size of the iris assembly. When the sizing key is coupled to the rotating body, the rotating body has a second range of rotation corresponding a second minimum size of the iris assembly, which is larger than the first minimum size of the iris assembly.
