Software is becoming the primary source of innovation across the medical device industry. Today's medical devices increasingly depend on software to diagnose disease, support clinical decisions, guide treatment, monitor patients remotely, analyze medical images, and deliver therapeutic interventions. At the same time, regulatory expectations continue to evolve.
The challenge is building software that can operate safely in patient care environments, withstand regulatory review, and scale after deployment. As part of our broader Healthcare Engineering Services practice, Zymr engineers medical device software across the full spectrum of SaMD and SiMD categories, combining clinical workflows, regulatory engineering, AI capabilities, device connectivity, and quality-system alignment into a unified development approach.

Understanding the Structural Differences
Software as a Medical Device (SaMD)
SaMD is standalone software built to achieve medical goals completely on its own, without being part of a physical medical device. It runs seamlessly on general purpose hardware like standard smartphones, tablets, or cloud servers.
- The Blueprint:
An artificial intelligence tool that processes medical images to flag potential tumor margins, or a mobile application that tracks home biometric trends to dynamically alter insulin dosing targets.
- The Engineering Priority:
Platform portability, secure consumer API gateways, and rigorous over the air change control protocols.
Software in a Medical Device (SiMD)
SiMD is embedded software, firmware, or microcode that serves as an internal component of a physical hardware medical device. It cannot function independently because its primary purpose is to drive, control, or power the physical equipment itself.
- The Blueprint:
The embedded code that controls the inflation rate of a digital blood pressure cuff, or the inner operating systems running an infusion pump or an MRI scanner.
- The Engineering Priority:
Hardware software interface validation, microsecond timing constraints, and strict hardware lifecycle synchronization.

SiMD & Embedded Firmware Development
While many healthcare software firms focus exclusively on applications, we engineer the software running inside the device itself.Our teams develop embedded firmware, RTOS-based systems, device-control software, sensor-processing engines, communication stacks, and connected-device architectures that support safe and reliable device operation across regulated environments.These initiatives frequently complement broader Medical Device Integration Services and IoMT Solutions programs.
Regulatory Documentation & V&V
Successful medical-device software requires more than functional code. It requires evidence. We help organizations establish regulatory-ready documentation frameworks including software requirements, architecture documentation, risk-management files, traceability matrices, test protocols, verification records, validation evidence, cybersecurity artifacts, and Design History Files (DHFs).This helps reduce submission risk while improving audit readiness.
Legacy Medical Software Modernization
Many regulated medical applications were built years ago and struggle to support modern interoperability, cloud-native architectures, cybersecurity expectations, AI-driven capabilities, and evolving user needs. We modernize legacy medical software through platform re-architecture, cloud enablement, interoperability enhancements, UI modernization, security improvements, and lifecycle updates while preserving regulatory continuity. Organizations pursuing connected-care strategies often combine modernization efforts with broader EHR Development Services and interoperability initiatives.
AI/ML SaMD with PCCP Engineering
This is one of the most important emerging areas in medical-device software. Building an AI model is only part of the challenge. The real challenge is creating a regulatory framework that allows the model to evolve safely after deployment. We engineer AI-enabled SaMD platforms that combine algorithm development, validation frameworks, explainability controls, model monitoring, drift detection, and Predetermined Change Control Plans (PCCPs) designed to support long-term regulatory compliance.These initiatives frequently leverage our broader AI/ML Services and MLOps engineering expertise.
Connected SaMD (CDSS, DTx & RPM)
Medical-device software increasingly operates within larger healthcare ecosystems. Clinical decision support tools exchange data with EHRs. Digital therapeutics interact with patient-engagement platforms. Remote monitoring solutions depend on connected devices, analytics engines, and clinician workflows. We engineer connected SaMD ecosystems that combine FHIR interoperability, clinical workflows, cloud-native infrastructure, patient engagement, and intelligent analytics into unified healthcare experiences.

The result is a more efficient and modern validation strategy without sacrificing compliance.
Frequently Asked Questions
What is medical device software development?
Medical device software development involves designing, building, validating, and maintaining software that performs medical functions or operates within medical devices. Depending on intended use, the software may be regulated under FDA, EU MDR, and other global medical-device frameworks.
What standards apply to medical device software?
Common standards include IEC 62304 for software lifecycle processes, ISO 13485 for quality management, ISO 14971 for risk management, IEC 62366 for usability engineering, and IEC 60601-1 for electrical medical-device environments.
What is the FDA 510(k) pathway for SaMD?
The 510(k) pathway allows manufacturers to demonstrate substantial equivalence to an existing legally marketed predicate device. Many SaMD products enter the U.S. market through this process, although De Novo and PMA pathways may apply depending on risk and novelty.
What is a Predetermined Change Control Plan (PCCP)?
A PCCP is a regulatory framework that defines how AI-enabled medical-device software can be updated after deployment. It establishes approved change boundaries, validation requirements, monitoring processes, and governance controls that support future model evolution.
What is the difference between IEC 62304 and IEC 60601-1?
IEC 62304 focuses on medical-device software lifecycle processes, while IEC 60601-1 primarily addresses the safety of electrical medical equipment. Many SiMD products require consideration of both standards.
How much does medical device software development cost?
Costs depend on product complexity, regulatory classification, software scope, AI requirements, validation effort, interoperability needs, cybersecurity requirements, and submission strategy. Regulated software typically requires additional engineering and quality activities compared to conventional software projects.
What is the difference between SaMD and SiMD?
Software as a Medical Device (SaMD) performs medical functions independently of dedicated hardware. Software in a Medical Device (SiMD) operates as part of a physical medical device and supports monitoring, sensing, control, communication, or therapy delivery.
Does my software qualify as a medical device?
The answer depends primarily on intended use, clinical claims, risk profile, and how the software influences diagnosis, treatment, monitoring, or patient care. Regulatory classification should be evaluated early in the product lifecycle.
How does agile development work in FDA-regulated software?
Agile development can coexist with regulated environments when supported by strong traceability, risk management, documentation controls, verification processes, validation evidence, and quality-system alignment throughout the software lifecycle.
How do you develop AI/ML-based SaMD?
AI-enabled SaMD development requires algorithm design, validation planning, explainability controls, risk management, monitoring frameworks, drift detection, lifecycle governance, and regulatory documentation alongside traditional software engineering practices.
What is Computer Software Assurance (CSA)?
CSA is the FDA's risk-based approach to software validation. It encourages organizations to focus validation effort on product quality, patient safety, and critical risks rather than excessive documentation activities.
How does Zymr price SaMD and SiMD development?
Pricing depends on the product category, regulatory pathway, validation scope, AI requirements, firmware complexity, interoperability needs, and engagement model. Organizations can engage Zymr through project-based delivery, dedicated medtech teams, or long-term GCC models.
