Through your infusion, you create a weapon that heals while it hurts.

Daily   ✦     Arcane, Healing
Minor Action      Melee touch

Target: One weapon or implement

Effect: Until the end of the encounter, once per round when an attack that uses the target as a weapon or an implement hits, one bloodied ally within 5 squares of the target's wielder regains hit points equal to 10 + your Constitution modifier.
As a free action, the target's wielder can end the effect when he or she hits a creature using the target in order to spend a healing surge. In addition, the target of that attack is stunned until the end of its next turn.
