Medical
requirements

Meeting the highest standards for medical devices requires more than just advanced technology. Safety, regulatory compliance, and quality must be ensured at every stage—from development to production.

Our batteries are developed under strict regulatory and quality frameworks, ensuring full traceability, risk management, and reliable change control. This guarantees not only product safety but also regulatory compliance for your medical applications.

01 Highest quality & safety

Within medical applications, highest quality and full traceability is required.

Safety-relevant failures are not permitted.

Quality system according to ISO 13485 is a must.

02 Meet regulatory aspects

Different regulatory requirements, depending on the application must be met. Additionally, the requirements are continuously growing.

The product itself but also development and production setup needs to be aligned with these requirements. (CE, FDA, MDR)

03 Risk management and documentation

D-FMEA and P-FMEA are required throughout the whole development process.

All documentation must be complete and consistent.

The supply chain must be secured to avoid any delivery shortfall.

04 Change management

All changes to the product or production process must be communicated, verified, documented, approved, and tracked throughout the product’s entire lifecycle.

Product lifecycle
management

Long-term reliability through structured processes, cross-functional collaboration, and continuous improvement.

At Wyon, Product Lifecycle Management (PLM) is more than a process—it's the strategic backbone of our long-standing zero-failure quality standard. It ensures that every product in serial production meets the highest expectations for reliability, performance, and long-term customer value. Our PLM team is the driving force behind this standard. They manage product-related decisions—from change requests to production challenges—ensuring quality is upheld throughout the entire lifecycle. Regular reviews and close cross-functional collaboration turn feedback into action, embedding a no-failure mindset into our DNA.

We follow a rigorous, long-term approval process that complies with all relevant regulations and includes direct, ongoing communication with our customers. Fast response times ensure we stay aligned with their needs.

Given the exceptional longevity of medical devices, our PLM approach reflects more than operational excellence—it represents a long-term commitment. By ensuring our products remain reliable throughout the full lifecycle of our customers' solutions, we reinforce trust and deliver enduring value.
