During our visit there, they requested that we design a fin that could be used for rehabilitation purposes in their facility. However, they wanted a fin that could be placed on a patient's existing socket and could be switched out from one patient to another.

From this idea we designed the Mechanical Fin. This design is unique and requires the user to remove his/her existing knee/pylon system to mechanically attach the swim fin. The proximal attachment of the fin can be placed to almost any socket (with either male of female receivers). This is a very simple procedure which will be explained to the user by his/her prosthetist in order to safely maintain alignment.
