endpoints: software functions as specified; visualization accuracy of STN and GPi/GPe structures; MRI to CT registration accuracy; image processing of CT images for lead segmentation; electrode orientation; lead detection functionality

Reported performance (0 observations)

FDA source did not state a quantitative performance metric — non-reporting is itself the signal.

Each value carries its own analysis unit and task — never compare or pool across devices. Source: 510(k) summary PDF.

    The FDA AI/ML device list shows a newer 510(k) K241083 (decision 2024-06-14) from Surgical Information Sciences, Inc. for a matching device line ("SIS System") — a new clearance for the same line is a change event.

    The FDA AI/ML device list shows a newer 510(k) K230977 (decision 2023-05-02) from Surgical Information Sciences, Inc. for a matching device line ("SIS System") — a new clearance for the same line is a change event.

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.
