We don't know yet. He did say that he needed Chise's arm and that he would hand over one of his one body parts in hope's of granting Chise his Curse. We know that Carthaphilius is now part of Chise, but we haven't received any explicit evidence or references to where it states that she is now immortal. All we can do is wait until someone tells us about Chise's current situation.
