Response

The IFU and label content was reviewed during the Phase 5 Product Validation design review (R-TF-012-026 Product Validation Phase 5 Checklist, section "Information Provided by Manufacturer"), which confirmed IFU completeness, intended use, contraindications, warnings, technical specifications, and label regulatory information. However, that design review verified content at the regulatory-checklist level rather than tracing each of the 26 individual labeling requirements defined in R-TF-012-037. This per-requirement traceability has now been added. The updated documentation is described below.

Verification and validation plan. The verification and validation of labeling and IFU requirements is a planned activity within our design and development process. GP-012 Design, Redesign and Development defines Phase 5 (Product Validation) activities, which explicitly include "Labelling / User manual / Translation" as a design phase activity subject to verification and validation. The verification method statement in R-TF-001-006 (described below) implements this planned activity by defining the scope (26 LR codes from R-TF-012-037), method (content review per EN 62304 § 5.5.2), items under review (IFU version 1.1.0.0 and device label), and acceptance criteria.

Verification record. A labeling requirements verification section has been added to R-TF-001-006 IFU and Label Validation (section "Labeling requirements verification"). This section contains:

• A verification method statement citing EN 62304 § 5.5.2, which permits verification by review, inspection, or analysis. The 26 labeling requirements (LR codes) are design inputs specifying information content that must appear in the IFU and/or device label; content review is the appropriate verification method for documentation requirements.
• A verification results table with one row per labeling requirement (26 rows), documenting for each: the LR code, requirement name, location (IFU and/or Label), the specific IFU or label section where the requirement is implemented, the acceptance criterion, and the verification result (pass/fail).
• A verification summary confirming that all 26 labeling requirements passed verification against IFU version 1.1.0.0 and the device label.

This verification record satisfies EN 62304 § 5.5 (all requirements verified, by review per § 5.5.2), EN 82304-1 § 5.2 (release documentation demonstrating the product meets specified requirements), and MDR Annex II 6.1(a)(b) (description of verification activities and evidence of adequate verification).

eIFU accessibility verification. In addition to the content review described above, the accessibility and navigability of the eIFU has been verified through automated software testing. Test case C543 (T384 in TestRail), mapped to software requirement SRS-BA6 ("Display the legal information about this medical device"), verifies end-to-end that the eIFU is reachable, accessible, and navigable via the link provided on the electronic label. The test procedure confirms: (1) the device API returns the eIFU URL in the instructionsUrl field, (2) the URL is a well-formed HTTPS address, (3) the eIFU responds with HTTP 200, (4) the content renders as a navigable Docusaurus site with the Instructions for Use, and (5) the eIFU contains identifiable device information (device name and manufacturer). This test case passed and has been reviewed and approved. The test evidence (API response, HTTP headers, browser screenshots of the eIFU site) is stored in the verification test artifacts. This test case has been added to the traceability matrix under SRS-BA6 and to the verification tests export.

Traceability. R-TF-012-043 Traceability Matrix has been updated with a new Part 4 ("Labeling Requirements (LR) to Verification Evidence") that traces the 26 LR codes to their verification evidence in R-TF-001-006. Additionally, the traceability matrix now includes test case C543 mapped to SRS-BA6, providing traceability from the software requirement for displaying legal information to the eIFU accessibility verification test. The coverage analysis has been updated accordingly to include labeling requirements: 26 of 26 labeling requirements have verification evidence (100% coverage).

Validation. Validation of labeling effectiveness — confirming that the IFU and label information achieves its intended purpose for users — is addressed through the summative usability evaluation (R-TF-025-007 Summative Evaluation Report), which tested IFU comprehensibility and usability with representative users per EN 62366-1. This satisfies EN 82304-1 § 5.3 (validation of the product for intended use).

Red-lined versions of R-TF-001-006 and R-TF-012-043 will be provided.
