I saw his Bankai shatter completely, so I doubt it was sealed.

It was stated by Granz that Renji would not be able to use his bankai in that room.

And what do you know on the next page he even states he sealed Renjis bankai.

"If that were the case, Ikkaku or Mayuri would have different Shikais "

Ikkakus and Mayuri bankais were remodeled with the same Asauchi. Renji and Ichigo got a whole new Asauchi.

"On a side note, do Bankai weapons have to be completely destroyed in order for them to never recover? Does that imply that they would recover if only a part breaks?"

If a bankai is broken/damaged in anyway they can not be repaired only remodeled to function at a level close to what the original was. Ichigo's bankai was cut/broken in half and was stated to not be able to be restored.

In addition it is stated by Mayuri that the parts of Renji's bankai that were broken in his fight with Byakuya never returned. Same with Byakuya's bankai in his fight with Ichigo. Ichigo took out a few of Byakuya's blades but not the whole thing. Mayuri stated those never returned either. But because Renji's and Byakuya's bankais are so large the missing parts were never a real problem.
