"QARA FDA 510k FDA Pre Submission process is used by the applicant to obtain feedback from FDA before actual submission for the 510 (k) clearance."

I would also speculate that BIEL is asking the FDA if a new 510k Clearance is required for the RecoveryRX XTRA since the electronics and function have not changed, just the shape of the antenna.
