  • Patent number: 11992249
    Abstract: A system includes an implant and a packaging device assembled with the implant to hold an outer sleeve and a head element of the implant in a desired position relative to one another. The packaging device includes clip arms sized and shaped so that, when the arms are held toward a closed configuration, the implant is housed therebetween in the desired position and proximal ends of the arms form a space via which an insertion device is insertable to be coupled to the implant, and a housing defining a space within which the clip is housed. The housing includes a retaining feature for retaining the clip therein and a camming element which, when a proximal force is exerted on the implant via the insertion device coupled thereto, causes the arms to move away from one toward an open configuration to release the implant therefrom.
