Comprehensive Guide to Software as a Medical Device (SaMD) Compliance & Global Registration

Introduction

The convergence of healthcare and advanced technology has transformed the way medical interventions are designed, delivered, and monitored. At the heart of this transformation is Software as a Medical Device (SaMD), software that performs medical functions independently of an associated hardware device.

Unlike traditional Software in a Medical Device (SiMD), which is embedded within a physical product, SaMD operates autonomously, often in the cloud, on mobile platforms, or within clinical decision-support environments. It powers diagnostic algorithms, remote monitoring, digital therapeutics, and AI-enabled decision support, all of which rely on robust data pipelines and advanced analytics.

As this ecosystem matures, regulators around the world are moving quickly to clarify Software as a Medical Device regulation, align expectations, and ensure that patient safety, performance, cybersecurity, and data integrity are preserved. For manufacturers, the challenge is twofold: understanding these evolving frameworks and building SaMD compliance and global registration strategies that can withstand scrutiny from multiple regulators.

This comprehensive guide explores the global Regulatory landscape, SaMD classification guidelines, lifecycle, and risk-management practices, and the emerging trends shaping the future of SaMD, providing a strategic lens for organizations seeking sustainable market access and competitive differentiation.

The MedTech Industry and the SaMD Revolution

What is SaMD, and how does it differ from other software related to Medical Devices

Software as a Medical Device (SaMD) is a subset of digital health, referring to standalone software designed for medical purposes like diagnosis, monitoring, or treatment of diseases, independent of hardware devices. Digital health broadly encompasses technologies such as apps, wearables, telemedicine, and data analytics to enhance healthcare delivery, efficiency, and patient outcomes, with SaMD representing regulated software tools within this ecosystem.

There are three (3) types of software related to Medical Devices:

• Software as Medical Devices (SaMD)
• Software in a Medical Device (SiMD)
• Software used in the manufacturing of a medical device

SaMD vs. SiMD: Key Distinctions

This distinction has practical implications for SaMD classification guidelines, documentation, and the technical content required for Software as a Medical Device registration in each jurisdiction.

Global Regulatory Landscape: Comparing US, EU, MDSAP, and India

Key frameworks include:

• IMDRF SaMD definitions and principles
• 21 CFR Part 820 (QSR / QMS requirements)
• FDA Quality Management System Regulation (QMSR)
• Total Product Lifecycle (TPLC) approach for continuous learning and improvement

Pathways for SaMD registration in the U.S.:

1. Device Listing and Establishment Registration – for Class I devices
2. 510(k) Premarket Notification – for devices with substantial equivalence
3. De Novo Classification Request – for novel, moderate-risk devices
4. Premarket Approval (PMA) – for high-risk, innovative devices

The FDA also promotes transparency and modernization through:

• SaMD Pre-Certification Program
• Predetermined Change Control Plan (PCCP), allowing AI/ML SaMDs to adapt under defined controls
• Cybersecurity guidance for medical devices

European Union – MDR Framework

Under the EU Medical Device Regulation (MDR) 2017/745, standalone software performing a medical purpose is classified as a medical device.

According to MDCG 2019-11 Guidance:

• Classification depends on intended purpose and impact on patient health.
• Manufacturers must demonstrate compliance with essential safety and performance requirements.
• A Notified Body assessment is required for higher-risk classes (IIa and above).

Key compliance elements under EU MDR:

• QMS certification per ISO 13485
• Risk management aligned with ISO 14971
• Software lifecycle processes as per IEC 62304
• Clinical evaluation and PMS following EU MDR Annex XIV and XV

MDSAP – A Unified Audit Model

The Medical Device Single Audit Program (MDSAP) enables a single Regulatory audit that covers multiple markets: the U.S., Canada, Brazil, Japan, and Australia.

Benefits include:

• Reduced Regulatory burden through unified audits
• Streamlined documentation and QMS consistency
• Improved readiness for global multi-market registrations

India – CDSCO and the Evolving Digital Health Framework

India’s Central Drugs Standard Control Organization (CDSCO) regulates SaMD under the Medical Device Rules, 2017.

• SaMD included under Class A to D based on intended use
• CDSCO is actively developing frameworks for AI-based diagnostic tools
• Manufacturers must obtain an Import License (Form MD-15) or Manufacturing License (Form MD-9), depending on the device category

The National Digital Health Blueprint (NDHB) and Ayushman Bharat Digital Mission (ABDM) aim to integrate SaMD into India’s broader healthcare digitalization efforts.

SaMD Lifecycle: From Concept to Sustained Compliance

A robust SaMD lifecycle integrates design, clinical, Regulatory, and post-market processes into a single, coherent system. The aim is not just to secure initial approval, but to support safe iteration and global scalability.

Concept and Planning

The lifecycle begins with a clear definition of the SaMD’s intended medical purpose, patient population, use environment, and clinical benefit. At this stage, organizations evaluate which SaMD classification guidelines apply across target markets (FDA, EU MDR, TGA, MHRA, CDSCO, etc.) and determine a Regulatory strategy that covers all relevant SaMD approval requirements.

Strategic planning should also consider which QMS software for medical devices, tools, and processes will be used for documentation, design control, and lifecycle traceability.

Development and Validation

During development, manufacturers operationalize design controls and SDLC processes in line with IEC 62304. Requirements, architecture, implementation, and verification activities must all be traceable and mapped to risk controls.

This is where QMS software medical device platforms become critical, helping teams manage:

• Design history files and configuration management
• Risk control implementation and verification of evidence
• Cybersecurity controls and usability engineering outputs

Validation activities ensure that the final product meets user needs, performs as intended across environments, and is robust against foreseeable misuse and cybersecurity threats.

Clinical Evaluation

Clinical evaluation for SaMD involves demonstrating that the software delivers clinical performance consistent with its intended purpose. This may leverage:

• Prospective clinical studies
• Retrospective data analyses
• Real-world data from pilot deployments

International guidance, such as IMDRF’s SaMD Clinical Evaluation document, helps harmonize expectations.

For AI/ML devices, explainability, dataset representativeness, and bias mitigation must be considered core parts of clinical evidence, mainly where regulators are increasingly focused on transparency and fairness.

Regulatory Submissions

Once development and clinical evaluation are complete, manufacturers prepare region-specific dossiers and pursue Software as a Medical Device registration.

For example:

• In the US, submissions may proceed via 510(k), De Novo, or PMA.
• In the EU, MDR requires comprehensive technical documentation and Notified Body review, based on risk classification.
• In Australia, software as a medical device TGA requirements must be met, with classification and evidence aligned to TGA guidance.
• In the UK, software as a medical device, MHRA expectations are set by MHRA’s evolving post-Brexit device regulations.

Each of these processes reflects a distinct interpretation of Software as a Medical Device regulation, and aligning documentation across them is a core challenge for global SaMD manufacturers

Post-Market Surveillance and Vigilance

After market entry, SaMD must be monitored for safety, performance, and usability in real-world settings. Post-market surveillance (PMS) draws on incident reports, user feedback, performance analytics, and cybersecurity monitoring to identify emerging risks.

PMS obligations are integral to SaMD approval requirements globally and often include:

• Vigilance reporting for serious incidents
• Periodic safety or performance update reports
• Corrective and preventive actions (CAPA)
• Ongoing clinical follow-up in some jurisdictions

For AI/ML products, PMS also extends to monitoring model drift, performance degradation, and unintended behaviour resulting from changes in data distributions.

Sustenance and Lifecycle Maintenance

SaMD is rarely static. New features, cybersecurity patches, updated clinical logic, or artificial intelligence and machine learning algorithm retraining may all be required over time. These changes must be systematically assessed for impact on risk and performance, documented within the QMS, and, where necessary, notified to regulators.

Manufacturers increasingly rely on QMS software for medical devices and Regulatory intelligence platforms to manage this complexity, ensuring that product updates remain aligned with Software as a Medical Device regulation across multiple jurisdictions.

Risk-Based Approach: ISO 14971 and IEC 62304 in Practice

A risk-based framework is the backbone of SaMD compliance. It ensures that hazards are systematically identified, evaluated, mitigated, and monitored throughout the lifecycle.

ISO 14971 – Risk Management for Medical Devices

ISO 14971 provides a structured approach to risk management. For SaMD, this includes not just functional failures, but cybersecurity threats, data integrity issues, UI/UX-induced errors, and algorithmic risks.

The standard’s emphasis on traceability, from hazard identification through to verification of risk controls, aligns closely with global SaMD classification guidelines and is essential for robust SaMD approval requirements.

IEC 62304 – Software Lifecycle Processes

IEC 62304 defines the processes, activities, and tasks required across the software lifecycle. When paired with ISO 14971, it ensures that software development, maintenance, and problem resolution are executed in a controlled, auditable way.

Together, these standards provide regulators with confidence that SaMD manufacturers have embedded risk thinking into their engineering practices, rather than treating risk management as a “paper exercise.”
