Embedded Product Development for Medical Devices
Most connected medical products stall not in the lab but at design transfer, when the design history file cannot prove what the prototype already did. We run the whole embedded program — applied-part safety classification, mechanical and enclosure design, electronics, embedded software and verification — inside an ISO 13485 quality system. The scope is non life-support connected devices such as vitals monitors, wearables and bench analyzers, not implantable or life-support instruments.
Challenges specific to Medical Devices
Safety classification is decided too late
The applied-part type and means-of-protection are pinned down only at verification, after the architecture is frozen, forcing a rework of the power and patient interface.
Prototype works but cannot be transferred
A bench-proven unit has no design output records, so manufacturing and the quality team cannot reproduce or release it during design transfer to production.
Risk file and requirements drift apart
Hazard analysis lives in a spreadsheet disconnected from requirements, so a reviewer cannot trace each mitigation to a verified design output and test result.
Embedded software lacks a defined lifecycle
Firmware was written ad hoc without a software safety class, architecture record or unit-level evidence, which an IEC 62304 review will not accept.
Cleaning and reprocessing break the enclosure
An enclosure that passed bench testing degrades after repeated wipe-down or autoclave cycles because materials and ingress sealing were never validated for reprocessing.
Usability hazards surface in summative testing
Use-related risks found in late human-factors evaluation force interface and labeling changes after tooling, blowing the launch schedule and budget.
How GizanTech solves them
- Early safety classification and architecture. We fix the IEC 60601 applied-part type, means-of-protection and energy budget at concept, then anchor the power, patient-interface and partitioning architecture to it before freeze.
- Design transfer and production-ready outputs. We produce design outputs — drawings, specifications, build and inspection instructions — so manufacturing reproduces and releases the unit cleanly during design transfer.
- Risk management linked to requirements. We run ISO 14971 hazard analysis and trace every mitigation to a requirement and a verification result inside the quality system, not a detached spreadsheet.
- IEC 62304 embedded software lifecycle. We assign a software safety class, document the architecture, and deliver unit, integration and system test evidence for the firmware and connectivity stack.
- Reprocessing-validated enclosure and ingress. We select materials and seals rated for the chosen wipe-down, disinfection or autoclave regime and validate IP ingress and mechanical integrity after repeated cycles.
- Human-factors engineering and V&V. We run IEC 62366 formative and summative usability studies early, then close the full verification and validation campaign feeding the design history file.
| Requirement | Standard | GizanTech deliverable |
|---|---|---|
| Safety classification | IEC 60601 | Applied-part type and means-of-protection determination with the supporting energy and patient-interface analysis |
| Patient isolation and leakage budget | IEC 60601 | Isolation-barrier and leakage-current budget across the product, verified against the dielectric and leakage acceptance limits |
| Biocompatible materials and contacts | ISO 13485 | Material and surface specification for patient-contacting parts with ISO 10993 / USP Class VI evidence in the device master record |
| DFM to high-reliability build | IPC Class 3 | Manufacturing and inspection package built to IPC Class 3 acceptance with documented stack-up and process controls |
| Design traceability | ISO 13485 | Requirements-to-risk-to-verification trace matrix and ISO 14971 risk file linking each mitigation to a test result |
| Verification, validation and documentation | IEC 60601 | Full V&V protocols and reports plus the assembled design history file ready for technical-file or 510(k) submission |

Frequently asked questions
Do you build life-support or implantable devices?
No. We develop turnkey non life-support connected products such as vitals monitors, wearables and bench analyzers under ISO 13485, IEC 60601 and IPC Class 3, not implantable or life-support instruments.
What does a turnkey embedded program include?
It spans concept, enclosure and mechanical design, electronics, embedded software, connectivity and the full verification campaign, delivered with the design history file that supports your regulatory submission.
Why classify device safety at the concept stage?
The applied-part type and means-of-protection drive the power architecture and patient interface. Deciding them at concept avoids a rework cycle when verification later exposes an isolation or energy gap.
How do you make a prototype survive design transfer?
We generate complete design outputs — drawings, specifications and build and inspection instructions — under design controls so manufacturing can reproduce, inspect and release the unit without reverse-engineering it.
How is embedded software handled for compliance?
We work to the IEC 62304 lifecycle: a documented software safety class, an architecture record, and unit, integration and system test evidence for the firmware and connectivity, all folded into the design history file.
