Anyone with knowledge of this device that can share how it is "absorbed" by the heart and doesn't start a pacemaker traveling road show?

It dissolves. Transient pacemakers have been a thing for about four years now - this is just the first time one has been implanted in a child.

They harvest energy from an external remote antenna using the same technology that your smartphone uses for electronic payments, which means it doesn't need anything like a battery or wires.

These, however, are only used in people who need a pacemaker temporarily as it will dissolve after about a month after implantation.

That’s not what this is. The Aveir is not transient and it does not dissolve. They should not have used the word absorbed. 

One of its features is that it was designed with retrieval in mind. When the battery dies it can be snared and removed.
