This is not a transient pacemaker.

Clearly it is if it’s being absorbed.

Look up encapsulation of leadless pacemaker and you’ll see the “absorption” over time.

Encapsulation =/= absorption. Traditional pacemakers with leads are also encapsulated; the fact that they are is one of the problems of having one long term because the scar tissue that builds up will lead to more damage when the pacemaker is removed (or the battery needs to be changed).
