I'm a little surprised it is your player. That is unless you used the force wrench to pickup/remove the conduit. I'm not sure if MCEdit can do that to a player. If it can open the player.dat or your minecraftname.dat then you use it. Either way backup the file to be safe. If MCEdit is no help delete it from the save folder. This will get rid of all the items in your inventory and on your hot-bar. To get the items back refund them with NEI.
