FDA-cleared profile

JBS-LVO

JLK, Inc.

Notification-only parallel workflow analysis of acute brain CTA to identify suspected large-vessel occlusion in the terminal ICA or MCA-M1 and notify a neurovascular specialist for image review; the finding is not for diagnosis beyond notification.

Evidence status: each field states its source quality, applicability, and review date. Research pending, information not established, and vendor documentation pending remain distinct outcomes.

Care setting and population
Hospital-network acute-care workflow operating in parallel with standard-of-care image interpretation.
  • FDA source
  • Exact FDA submission
  • Checked 2026-09-08
Workflow role
Parallel triage and notification for suspected LVO, with mobile informational preview and specialist communication; notified clinicians must review non-compressed images and complete patient evaluation.
  • FDA source
  • Exact FDA submission
  • Checked 2026-09-08
Required input
DICOM CT angiography images of the brain acquired in the acute setting, focused on terminal ICA and MCA-M1 vessels and transmitted to the JLK server.
  • FDA source
  • Exact FDA submission
  • Checked 2026-09-08
Output and human action
A binary positive or negative suspected-LVO flag, notification to a neurovascular specialist recommending image review, and a compressed mobile preview for informational triage only; the original image is unchanged.
  • FDA source
  • Exact FDA submission
  • Checked 2026-09-08
Limitations
The device does not process scans containing metallic artifacts. It is limited to the labeled terminal ICA and MCA-M1 LVO use. The mobile preview is compressed and not diagnostic; the device must not be used in lieu of full patient evaluation or to make or confirm a diagnosis.

Use these fields to structure a vendor demo, security review, and implementation estimate.

Integration
The locked AI algorithm is hosted on the JLK server, receives applicable CTA images in DICOM format from CT systems, and sends notifications and previews through a mobile application. Exact hosting, PACS, RIS, EHR, security, and local interface compatibility are not established.

Evidence

Performance evidence

Metrics are shown only when they are tied to a source, endpoint, population, and tested product version. Candidate literature without exact product and version linkage is not shown as product evidence.

Evidence summary
FDA standalone retrospective performance testing used an independent dataset with ground truth from two U.S. board-certified neuroradiologists and a third adjudicator when needed. Sensitivity was 91.8% (95% CI 85.8%-95.8%), specificity was 92.8% (95% CI 87.2%-96.5%), and AUC was 95.6% (95% CI 93.0%-98.1%). CTA-to-notification time ranged from 2.32 to 3.29 minutes, with mean 2.95 minutes (95% CI 2.89-3.02), against a target of 3.5 minutes or less.

Safety and lifecycle

Postmarket record

Recall and adverse-event records are shown only after product matching. Adverse-event reports do not establish incidence or causality.

Postmarket safety review
The exact-identifier FDA recall query returned no native recall record for K241480. This limited result does not establish absence of recalls or other safety information and does not cover later versions, family records, MAUDE reports, corrections, or field notices.

Exact-submission ACR model-card fields were normalized under the current provenance rules; vendor and independent-study confirmation remain distinct. Exact FDA scope controls clinical claims. ACR provides bounded exact-submission catalog context. Candidate literature metadata remains a discovery queue until full-text identity, endpoint, population, and version review is completed. Automated exact-name discovery found 0 PubMed and 0 ClinicalTrials.gov candidate records. Candidates require human product and version matching; zero candidates is not evidence that no studies exist. Native FDA recall identifiers produced 0 postmarket candidate records; 0 have been reviewed (0 published, 0 rejected) and 0 remain unreviewed.

Candidate leads remain unpublished until a human confirms the exact product and tested version.
