    摘要： A stent crimping assembly is provided for crimping a stent from a first diameter to a reduced second diameter. The crimping assembly includes a plurality of movable wedges disposed about a rotational axis to form a wedge assembly. Each wedge includes a respective first side and a second side converging to form a tip portion. The tip portions are arranged to collectively form an iris about the rotational axis thereof. The iris defines a crimp aperture about which the movable wedges are disposed. A control unit is electronically programmed to control the mechanical components. A method of calibrating the control unit includes inserting a quill of known diameter into the iris and reducing the diameter of the iris onto the quill.

    摘要： A stent crimping apparatus is provided which includes a crimping assembly adapted to crimp the stent, a clamp assembly configured to secure the medical device; and a control unit configured to control the movement of the crimp assembly. The clamp assembly includes a lower clamp device defining a seating groove formed and dimensioned to seat a portion of the medical device therein, and a retaining assembly having an elastomeric member. This elastomeric member defines a contacting groove oriented in an opposed manner proximate to at least a portion of the seating groove. The clamp assembly further includes an actuation mechanism associated with the retaining assembly and the lower clamp device such that operation thereof causes the retaining assembly to move between an opened condition and a closed condition. In the opened condition, the medical device can be positioned between the lower clamp device and the retaining assembly, and in the closed condition, retaining the medical device between the contacting groove of the elastomeric member and the seating groove of the lower clamp device.
