A deployment device for a prosthesis includes a driving assembly, including a driving tube and a driving pin. The deployment device also includes a driven assembly, including a driven tube and a driven pin. The driven pin and the driven tube may be further associated with the prosthesis. The driving tube, the driving pin, the driven tube and the driven pin may all be located coaxially, with the driving pin configured to translate through a cavity in the driving tube and the driven pin configured to translate through a cavity in the driven tube. This configuration allows for a two-stage implantation process for the prosthesis, as the driving tube and driving pin may move together in one stage and may move relative to one another in a second stage. |
