I was thinking a basic medigun look with the spooked effect going from the medigun to the person being healed instead of the default red or blu effect. Btw the name means chicken pox healer. It's supposed to be an op over affected medigun that is a challenge to face and use. While you have a medic you will be a challenge to defeat but if you don't defend him/her properly you will end up not only without a medic, but with bleeding and massive overheal (these are supposed to counter act each other to add another element to gameplay).
