These relate to registered appearance or design rights. They are not certificates of chamber pressure safety, electrical safety or clinical effect.
Model- and market-specific evidence
Request final drawings, relevant test or compliance documents, user instructions and any other evidence required in your destination market. Availability and applicability must be confirmed by the manufacturer.
Verification note
A design patent is evidence about a design right. It is not evidence that a specific chamber configuration is approved, safe or effective for a medical use.
