Software as a Medical Device, from definition to CE mark.

SaMD is a medical device in its own right, and EU MDR treats it accordingly. Understand the IMDRF definition, why Rule 11 raises the stakes, and the clinical evidence standalone software actually needs.

The framework

Why software becomes a regulated device.

When software has a medical purpose without being part of a hardware device, it is SaMD, and EU MDR and the FDA regulate it as a device, with classification driving everything that follows.

01

What SaMD is

The IMDRF defines Software as a Medical Device as software intended for one or more medical purposes that performs those purposes without being part of a hardware medical device. A wellness or general-fitness app is not SaMD; software that diagnoses, screens, monitors or informs treatment is. That single distinction decides whether you are in scope at all.

02

Classification: Rule 11 raises the stakes

In the US the FDA applies a risk-based Class I/II/III model. In the EU, MDR Rule 11 governs software, and it is demanding.

Why Rule 11 matters

  • Software providing information used for diagnosis or therapy is at least Class IIa
  • Serious deterioration or surgical intervention decisions push it to IIb
  • Death or irreversible deterioration decisions reach Class III
  • Most clinically meaningful SaMD leaves Class I behind, and needs a Notified Body

03

The evidence SaMD needs

The IMDRF clinical evaluation framework for SaMD rests on three levels: a valid clinical association (is the output meaningfully linked to the clinical condition?), analytical validation (does the software process inputs correctly?), and clinical validation (does it achieve the intended purpose in the target population?). Alongside sits the IEC 62304 software lifecycle, risk management to ISO 14971, and cybersecurity, all feeding the Clinical Evaluation Report (CER).

04

After launch: software never stands still

SaMD evolves through updates, and each material change can affect safety, performance and even classification. A robust PMCF plan for software tracks real-world performance, model drift where AI is involved, and the impact of new versions, keeping the clinical evaluation and CE mark valid over time.

Questions we hear first

Software as a Medical Device, answered.

What is Software as a Medical Device (SaMD)?
Per the IMDRF, SaMD is software intended for one or more medical purposes that performs those purposes without being part of a hardware medical device. Software that diagnoses, screens, monitors or informs treatment is SaMD; a general wellness app is not.
How is SaMD classified in the EU?
EU MDR Rule 11 governs software. Software providing information used for diagnostic or therapeutic decisions is at least Class IIa, rising to IIb or III as the potential harm increases, so most clinically meaningful SaMD requires Notified Body involvement.
What clinical evidence does SaMD need?
The IMDRF framework requires a valid clinical association, analytical validation and clinical validation, supported by the IEC 62304 software lifecycle, ISO 14971 risk management and cybersecurity, all documented in the Clinical Evaluation Report.
Does SaMD need PMCF after launch?
Yes. Because software evolves through updates and, for AI, can drift, a PMCF plan must track real-world performance and the impact of new versions to keep the clinical evaluation and CE mark valid over time.
