A leg wound, preventing him from walking, requiring his own wand to heal or some machinations on V’s part to find some non-magical interaction way to heal/move Harry would have also done nicely.
To what end? He already has his wand back at that point, so this would merely be a slight inconvenience to V (but a great inconvenience to himself).
Also, for what it’s worth, Harry still has the Healing Pack (which he bought in chapter 7) in his pouch, right? So there’s a way to heal him without any magical interaction between V and H; even if H doesn’t know the appropriate healing spells.
