FDA-cleared profile
Rivanna Medical, Inc.
Portable B-mode ultrasound with SpineNav-AI supports lumbar spine scouting and epidural-depth estimation for neuraxial anesthesia and needle or catheter placement.
Clinical fit
Start with the authorized purpose, then verify how it fits your service line and reading workflow.
Regulatory identity
The FDA listing establishes the regulatory identity. It does not by itself establish local workflow fit, pricing, security, or performance in your environment.
Implementation
Use these fields to structure a vendor demo, security review, and implementation estimate.
Public materials reviewed for this exact release do not establish the complete security posture. Request data-flow, identity, audit, encryption, retention, remote-access, vulnerability-management, backup, and incident-response evidence.
Map the installed model, build, options, population, anatomy, inputs, and outputs to K243937 before acceptance.
exact submission · checked 2026-09-03Later product-family features are not evidence that this cleared release includes them.
Validate supported probes and host devices, patient matching, DICOM or local export, PACS measurements, worklist, report transfer, and offline or downtime behavior.
exact submission · checked 2026-09-03Test representative identifiers, orientation, geometry, measurements, units, routing, failure handling, and round trips locally.
Use a signed local test set for the supported population and workflow. Include common and difficult cases, exclusions, acquisition variation, failed or low-quality inputs, reviewer overrides, and downstream effects. K243937 supports the cleared scouting and measurement workflow. Later product-family claims about real-time in-plane guidance are not attributed to this release without exact clearance evidence.

Model capital and recurring cost against net staff time after review, throughput, repeat imaging or rework, room time, consumables, infrastructure, training, service, downtime, upgrade, and replacement costs.
product family · checked 2026-09-03Vendor productivity claims are scenario inputs, not guaranteed local savings.
Monitor by exact hardware, software and model version, patient population, anatomy, protocol, operator, input quality, output edits or overrides, failed studies, repeat acquisition or rework, downstream impact, downtime, incidents, recalls, and updates. Track these product-specific limits: K243937 supports the cleared scouting and measurement workflow. Later product-family claims about real-time in-plane guidance are not attributed to this release without exact clearance evidence.

Economics and lifecycle
These are common procurement questions; unknown values remain visible until a source supports them.
No public list price for the exact cleared configuration was found. Obtain a written quote separating hardware or license basis, enabled features, implementation, interfaces, infrastructure, training, service, upgrades, renewal, consumables, and exit costs.

Safety and lifecycle
Recall and adverse-event records are shown only after product matching. Adverse-event reports do not establish incidence or causality.
Exact-identifier review does not prove absence of all product-family safety signals.

Research record
This audit distinguishes completed source review from fields that have not yet been researched.
Recovered from the prior exact-submission extraction and normalized under the current provenance rules. Exact FDA materials, available current product-family sources, reimbursement context, and exact-identifier postmarket results were reviewed. Pricing, contracted services, enabled options, final security architecture, and local interoperability remain organization-specific evidence. Automated exact-name discovery found 0 PubMed and 2 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.
