The Healbomb Launcher
This weapon concept is actually coming in the future for the 2.2 update for TF 2 Classic. I am not in the beta testing, meaning I have no idea how that one looks/works. So instead I've made my own version with the current attributes at my disposal
there is no server where you can play with this, but you can now download the pack yourself and test it on offline server: https://gamebanana.com/mods/481173 (updated every few weeks)

Also keep in mind these weapons are proof of concept, so if you have a suggestion for a change tell me in the comments
