Premarket evidence — what FDA accepted

Device typehardware with ml
source quote (p.6)
“The purpose of this Special 510(k) Pre-Market Notification is to modify the Segmental Wall Motion and introduce Auto EF with contrast software application onto the Philips EPIQ Series Diagnostic Ultrasound System and Affiniti Series Diagnostic Ultrasound Systems. No hardware changes to the EPIQ or Affiniti systems were made due to the SWM v2 and Auto EF with contrast, and existing, cleared Philips TTE transducers are used with these software applications.”
AlgorithmThe SWM v2 software is a semi-automated quantitative imaging algorithm. Auto EF with contrast is an AI based automated software feature.
source quote (p.6)
“The SWM v2 software is a semi-automated quantitative imaging algorithm, as users are generally expected to review and concur with the initial and generated results. The users can also manually edit algorithm-generated segmental wall motion scores for individual segments based on their clinical expertise. Auto EF with contrast is an Al based automated software feature that assists clinicians with assessing Left Ventricular Ejection Fraction (LVEF) from images acquired with contrast agent as part of an adult transthoracic echo (TTE) examination.”

    recall event 97217 (openFDA)

Recall and MAUDE counts are product-code-level (reports aren't reliably attributable to one device); a recall is shown as device-attributed only when the recall record itself lists this clearance number. Signals are descriptive observables with sources — never a judgment that the device is unsafe or drifting. Snapshot 2026-07-08.

Reimbursement — how devices like this got paid

Not yet tracked — no payment pathway indexed for this clearance (the reimbursement corpus is a growing seed set).

Applicable FDA guidance — what the submission is measured against

FDA guidance documents and guiding principles applicable to 510(k) AI/ML devices in the Radiology panel. A curated reference index, not legal or regulatory advice — each item states its own status, and a draft is never binding.

Applicability is derived from the device's FDA advisory panel and pathway — cross-cutting guidances apply to every AI/ML device; panel-specific ones are flagged. Titles, dates, and links verified against fda.gov as of July 2026.
