IEC 62304 Medical Device Software Lifecycle
by Nick Clark | Published April 25, 2026
IEC 62304 establishes the international standard for medical-device software lifecycle. Spatial-adaptation provides the architectural substrate for emerging continuously-improving medical-AI software.
IEC 62304 Frame
IEC 62304 (Medical device software — Software lifecycle processes) establishes safety-class structure (A/B/C) with C the most stringent for software where failure could cause death or serious injury.
Architecture Implications
Class-C medical software increasingly faces emerging continuously-improving AI-software requirements that traditional waterfall lifecycle handling does not support effectively.
Architectural Mapping
Runtime-signed adaptation artifacts map to medical-software update authority. Sandbox pre-activation maps to safety-class-appropriate verification. Cascade-deactivation maps to medical-software incident response.
Standard Evolution
IEC 62304 emerging revision integrating AI/ML capabilities and emerging FDA PCCP framework integration both push toward structurally-supported architecture.
