What Do Medical Device Software Development Companies Do?
Medical device software development companies are specialized providers focused on building software for healthcare and medical devices. Unlike general software vendors, they operate within regulated quality systems and follow medical standards such as IEC 62304 (software lifecycle) and ISO 13485 (quality management).
They support both:
- Software as a Medical Device (SaMD)—software that performs a medical purpose without being part of a hardware device.
- Embedded medical software—software running on or in a device.
Beyond coding, these firms manage regulatory engineering, usability/human factors, risk management, clinical validation planning, and post-market surveillance—so products are not only functional but also safe, effective, and compliant.

- Hazard analysis and risk control per ISO 14971, covering software and its interaction with the overall device and use environment.
- Requirements engineering with full traceability; early pathway assessment and, where appropriate, FDA Q-Sub meetings.
2) Design & Implementation
- Architecture emphasizing safety, reliability, and separation of safety-critical functions.
- Coding standards (e.g., MISRA C for embedded) and static analysis for early defect detection.
- Unit, integration, and system testing aligned with IEC 62304; configuration management and change control in validated environments.
3) Verification & Validation
- Code reviews, static analysis, and verification against specifications.
- Usability/human factors and, where applicable, clinical validation to demonstrate safe and effective performance in real-world contexts.
- Interoperability testing (e.g., electronic health records/EHR, imaging networks) and performance testing.
- Preparation of the regulatory submission package and management of review interactions.

Why Work with Specialized Partners?
Regulatory Expertise & Compliance
Experienced partners know the submission landscape and current expectations, which helps avoid redesigns and incomplete documentation. This typically leads to smoother reviews and fewer cycles of questions.
Cost & Time Efficiency
Established processes, reusable frameworks, and specialized expertise can reduce rework and internal overhead. Many companies find that partnering is more efficient than building a full in-house regulated software capability for one or a few products.
Technical Excellence & Innovation
Specialists keep pace with evolving best practices (e.g., cybersecurity, AI/ML, interoperability) and bring proven patterns that scale with your portfolio—without locking you into outdated architectures.

Frequently Asked Questions
How long does development and FDA review usually take?
Timelines vary by device class, complexity, and evidence requirements. Typical ranges are 12–24 months for many Class II solutions and 24–36 months for complex Class III solutions. Experienced partners can reduce delays by anticipating documentation needs and reviewer expectations.
What’s the difference between SaMD and embedded software from a regulatory standpoint?
SaMD is regulated based on intended use and risk as a standalone medical product; embedded software is assessed as part of the overall device. Both adhere to IEC 62304, but SaMD often emphasizes cloud/mobile security, interoperability, and lifecycle monitoring.
How is cybersecurity addressed?
Partners implement risk-based security (threat modeling, secure design, encryption, access control, audit logs), conduct testing (e.g., penetration tests), and establish post-market vulnerability monitoring and incident response—aligned with current FDA cybersecurity expectations.
What should I look for in a partner?
Verify ISO 13485 certification, relevant Class I–III experience, device-type familiarity, submission history, documentation quality, usability engineering competency, and a clear approach to post-market support. Ask for references and sample documentation.
How are updates handled after launch?
Updates follow formal change control, risk assessment, and regression testing. Depending on impact, some changes may require additional regulatory submissions. Robust post-market surveillance feeds continuous improvement while maintaining compliance.
