I don't recall any reference to LS healing/sustaining Big Ds or Alpha Series in Bio2 with their ADAM. I think the bond in that game was simply a physiological/mental connection, but they never said it was a blood transfusion. If they walk away from their LS, they lapse into a coma, and if she dies, they go mad.
