The other 2 pending actions are split between the remaining 2 distinct examiners. The 3 distinct art units involved suggest that the company's filings cover several different technical sub-fields within the medical and mechanical area.

CHRISTEN PILAR BROWN-LORRIG, as the busiest examiner with 2 pending actions, is the primary point of contact. The 4 pending office actions and 3 distinct art units indicate that the company must navigate multiple sets of examination guidelines even with a small number of applications.
