Developing Software as a Medical Device (SaMD) is a meticulous process, blending technological expertise with regulatory understanding. This guide delves into the various stages of SaMD development, highlighting the importance of market research, design precision, expert validation, and regulatory navigation. This blog offers a comprehensive roadmap for those looking to venture into or refine their approach to SaMD.
$23.26 billion – that's the potential valuation of the global market for connecting medical devices with healthcare IT platforms by year's end. With a robust CAGR of 25.2%, the surge in software development for medical devices is undeniable.
“From standalone medical devices to integrated software-device solutions, we're experiencing more streamlined care delivery and operations,” says Dr Aakash Doshi, CEO of Montar Healthtech.
But the potential of these medical devices isn't just in their standalone capabilities. Collaborating with device manufacturers and digital partners can lead to a more holistic approach to healthcare delivery.
By developing digital pathways, we can ensure that medical device usage integrates seamlessly into operations. This integration allows for a powerful combination of remote monitoring, real-time data analysis, and in-person consultations, ensuring that technology truly enhances patient outcomes.
Before we look at software development for medical devices, let’s start with the basics!
Terms like "medical device software" and "software as a medical device" often get used interchangeably. However, understanding their nuances is important for healthcare software product development.
Medical device software is a component or accessory of a medical device. Its primary role is to enhance the device's functionality, control, or monitoring capabilities. The safety, effectiveness, and regulation of medical device software are intrinsically tied to the overall medical device. It's not just about the software but how the software and the device function as a cohesive unit.
These devices have components like microcontrollers, microchips, microprocessors, and built-in memory, which can be programmed. Medical devices that use embedded systems, powered or configured by this intricate coding, include:
On the other hand, SaMD stands out as software that functions independently without being part of a physical medical device. It holds medical significance in its own right for diagnosis, prevention, monitoring, treatment, or disease alleviation. In other words - the software itself is the primary medical tool. It's designed to run on standard computers and infrastructure.
SaMD can utilise various tools, from specialised medical sensors to webcams or microphones. Its versatility allows developers to employ various programming languages and technologies, from web-based to mobile development.
Such software typically handles tasks like:
The SaMD market, growing at a CAGR of 51.88%, highlights its potential, driven by the industry’s adoption of IoT, or the “internet of things.” Within a healthcare ecosystem, there is potential to use a large number of software at any given time. These systems and devices should work seamlessly together for operations to run smoothly, as disjointed networks could be chaotic - ultimately harming patient outcomes and, of course, the bottom line.

Developing Software as a Medical Device (SaMD) requires a blend of technological expertise, regulatory understanding, and ethical commitment. So, let's dive deeper into each phase of this intricate process to provide a clearer perspective.
"Market research is the bridge between what you think and what your customers truly want.”
Laying a solid foundation starts with comprehensive market research. For instance, considering the rising global diabetic population, a study might reveal a gap in user-friendly diabetes management apps tailored to the elderly. This discovery can be the spark for a new SaMD solution. The feasibility of this idea needs evaluation. Questions will arise: Will the target demographic be receptive to such a tool? Are there existing solutions, and if so, what gaps do they leave unfilled?
At the heart of any successful digital health pathway is the user—the patient and the healthcare provider.
(a) Designing software interfaces that are intuitive and user-friendly ensures that patients can easily navigate and use the system.

(b) The design phase is where the concept takes form. The design must stay true to the initial vision. If the primary goal was to offer a user-friendly interface, especially for seniors, the design should avoid complex navigation or jargon.
New methodologies are available which help simplify the design process. To find out more about how you can upgrade your design process using these tools, check out our blog on Design Thinking
(c) A dynamic platform that can manage, update, and disseminate clinical guidelines and device usage instructions will bring more value to the end users. Open communication channels empower patients to seek guidance, share data, and collaborate with healthcare professionals, fostering a more integrated care approach.

(d) As the design crystallises, the development phase kicks in. Here, a Minimum Viable Product (MVP) can be a game-changer. Finalise a basic version of the software to start with. Early adopters can test this MVP, providing invaluable feedback that shapes the final product.

Before a full launch, the SaMD solution should undergo rigorous validation. This is where industry experts come into play. For an asthma prediction app, insights from pulmonologists or environmental health experts can be invaluable. Their feedback can refine the tool, ensuring it's both medically sound and user-centric.
Every region has its regulatory framework. For SaMD developers targeting the European market, compliance with the EU's Medical Device Regulation (MDR) is essential. Meanwhile, in the U.S., the FDA's guidelines for SaMD provide the roadmap. Beyond these, understanding global standards, such as ISO regulations, ensures the SaMD solution is universally compliant.
Patient safety and data privacy need to be well protected at a time when cybersecurity threats are on the rise. Sensitive personal data should be encrypted and stored securely, especially when transmitted from devices. Adhering to medical data privacy regulations ensures legal compliance and builds patient trust.
As the number of connected devices grows, the software architecture must be robust enough to handle this expansion. Scalability ensures that the software remains efficient and responsive as more patients adopt and use the system.
The ultimate goal is to create software that places power in the hands of patients, allowing them to monitor their health actively. By providing healthcare providers with comprehensive data, they can make informed decisions, offering proactive interventions and truly personalised care.
Building a Software as a Medical Device (SaMD) is more than just coding; it's a structured journey from initiation to deployment. As we've explored, understanding the market, ensuring design precision, validating with experts, and navigating regulatory landscapes are all crucial steps. But what’s the endgame? A software that stands autonomously, enhancing healthcare delivery and outcomes. The right software can turn a good digital health solution into a great one!
