Afterwards Touma supressed that "invisible power" inside him and restored his arm, sealing it and returning IB to it´s normal output... Or at least that´s how i interpret it.

I interpret it as a trinity in Touma:
1. The "invisible thing".
2. Touma's real power which is greater than 1 enough to crush it.
3. IB which acts as a lock for 2 while is restraining 1.

It has his own blood as a medium, yeah, very unstable.

At certain point they don't so anymore and just use different rules for thei own power.
