A real example

The SOP said 5 working days. The regulation said 2.

A UK device maker's complaints SOP gave the team 5 to 6 working days to evaluate a complaint. EU MDR can require a serious incident to be reported within 2. Nobody noticed until the audit.

Without Pathstone

Complaint handling SOP · §4 Evaluation

v1.0

Complaints are received and evaluated within 5 to 6 working days.

Minor NC at audit

With Pathstone

Complaint handling SOP · §4 Evaluation

v1.1

Complaints are evaluated within 1 to 2 working days. Potential serious incidents are escalated the same day for reporting under EU MDR Article 87.

Fixed before the audit

Had a serious incident come in, the SOP would have missed the reporting deadline. Under MDSAP, a finding like that is reported to every participating regulator, and repeat findings can cost you market access.

EU MDR Article 87 sets serious incident reporting deadlines of 2, 10 or 15 days depending on severity.

Human in the loop

Proposals, not silent edits.

Pathstone drafts. Your team decides. Every decision is on the record.

Pathstone proposes a redline, links the evidence behind it, and your team approves, edits or rejects it.

1 · Pathstone proposes

SOP-014 §5 Change evaluation

Draft

5.2 For each change, the developer shall document the affected software items

Inserted: and assess its effect on existing risk control measures, recording the result in the risk file.

Removed: Risk impact is reviewed at the next design review.

Proposed by Pathstone · nothing changed yet

Time

Weeks of document work, down to a review

One change ripples through SOPs, risk files and the technical file. Pathstone finds every affected document and drafts the update, so your team reviews instead of rewrites.

2–3 weeks
for one QA team to update their QMS after a single staff change
3–4 weeks
to answer one round of notified body questions

Money

Consultant days for judgement, not clause-checking

Small RA/QA teams pay consultants to map procedures to standards and prep submissions. Pathstone does that repetitive conformity work, without a full eQMS price tag.

Find the gap before the auditor does

Auditors go straight to open NCs and procedures that don't match the standard. Pathstone checks continuously and keeps every decision on an audit-ready trail.

open NCRs one quality lead inherited, with none closed to show the auditor

What Pathstone takes off your plate

Compliance isn't an audit. It's every week.

Each code change, dataset and threshold tweak can quietly put your file out of date. Here's the work that eats your week, and what Pathstone does instead.

  • Manual drafting

    Documents written from scratch or generic templates, translating engineering into regulatory language by hand.

    Cost: Weeks of writing per artefact

    What Pathstone does: Drafts the update for you

    Proposes the redline in regulatory language, with the ticket, test or clause behind every line.

  • Silent invalidation

    A retrain, new dataset or label change makes requirements, risk controls or claims wrong, and nobody notices.

    Cost: The file drifts away from the product

    What Pathstone does: Watches every change

    A merged PR, new dataset or label change triggers an impact check across the file, rated by severity.

  • Cross-checking by reading

    Consistency between risk file, requirements, tests, labeling and clinical evidence depends on someone reading it all.

    Cost: Gaps surface late, at review or audit

    What Pathstone does: Traces it end to end

    Links each requirement to its risks, tests and labeling, so one change shows everything it touches.

  • Know-how lives in heads

    What to do next, in which order, against which clause, is often unclear to a small team.

    Cost: Rework, detours and consultant dependency

    What Pathstone does: Checks SOPs against the clause

    Reviews your procedures against the standards you're certified to, and flags the ones that fall short.

Who it's for

Built for the small team that owns compliance

At most SaMD companies, two or three people carry the whole QMS, the technical file and the next audit. Pathstone is built for them.

  • Head of Quality / QA lead

    You own the QMS, the NC and CAPA log, and the next audit.

    Use Pathstone to

    • Check SOPs against your standards before an auditor does
    • Close NCs and CAPAs with the evidence already linked
    • Walk into surveillance and MDSAP audits without the scramble
  • Regulatory affairs lead

    You own the technical file, the submissions and the questions that come back.

    Use Pathstone to

    • Keep technical documentation in step with every release
    • Answer notified body and FDA questions with sources attached
    • Assess each change against significant-change criteria
  • CTO / engineering lead

    You ship the product. The file has to keep up without slowing you down.

    Use Pathstone to

    • See the regulatory impact of a PR before it merges
    • Keep requirement, risk and test traceability out of spreadsheets
    • Stop losing weeks to documentation catch-up before release

A good fit if you

  • Build SaMD or AI-enabled medical device software
  • Have a QA/RA team of one to five people
  • Ship software changes monthly or faster
  • Submit to FDA, EU MDR or both, including via MDSAP
  • Run your QMS in an eQMS, SharePoint or Google Drive

Frequently asked questions

Does Pathstone replace our eQMS or our consultant?

No. Pathstone produces the content your eQMS stores and your consultant reviews, and works alongside both.

Is this only for audit prep?

No. Most regulatory work happens between audits: change control, risk updates, SOP reviews. Pathstone works on that day-to-day flow so audit prep stops being a scramble.

Who is accountable for what Pathstone produces?

The manufacturer, as today. Pathstone doesn't replace the PRRC, the Notified Body or clinical judgment, and every approval is recorded in the audit trail.

What if a draft is wrong?

Reject or edit it. Each proposal links to the ticket, test, dataset or clause behind it, so you can check the reasoning before anything changes.
