## Abstract

A method and system of implanting multiple prostheses uses a deployment device including a front delivery assembly and a base assembly. The prostheses may be housed within the front delivery assembly and deployed using an impact force generated within the base assembly. The multiple prostheses can be implanted in quick succession. The deployment device uses power assistance generated from energy stored in an energy storage system. In one embodiment, a compression spring stores mechanical energy that can be transformed into an impacting force following a triggering event.
