Developing a medical device requires careful planning, from defining the initial concept to preparing for commercial production. Decisions made during development can affect how a device performs and how easily it can be manufactured at scale.
Understanding the medical device development process helps teams identify potential challenges early and make informed decisions as a product progresses towards market.
In this guide, we explore the key stages of medical device development, including where manufacturing expertise can support the transition from design to production.
1. Concept Development & Requirement Definition
Medical device development begins with defining the problem a product needs to solve. Teams establish its intended purpose and the requirements it must meet, taking into account its expected performance and how it will be used.
Applicable regulatory requirements and potential risks also need to be considered from the outset. For example, a wearable device designed for prolonged skin contact will have different material requirements from a component housed within diagnostic equipment.
Early manufacturing input can help teams assess whether their proposed design is practical to produce. Material selection and component construction can influence the manufacturing methods available, making these important considerations during initial planning.
At BDK, our full-service project management approach begins with understanding the customer’s brief and technical requirements, providing a foundation for identifying suitable materials and manufacturing methods.
2. Design Development & Prototyping
Once the requirements are established, the next step is to develop a workable design. Prototyping allows teams to assess how a proposed device functions and identify changes that may be needed before progressing further.
Material compatibility is particularly important when developing devices containing adhesive components. Adhesives may need to bond different substrates or maintain their performance under specific conditions, depending on the intended application.
Testing prototypes can help identify potential issues with component fit or adhesion before the design moves towards production. This gives teams an opportunity to refine the construction while changes are still relatively straightforward.
BDK supports medical device projects through prototyping and the development of bespoke adhesive components. Our manufacturing capabilities include specialist die-cutting, lamination, perforation, slitting and assembly to meet specific component requirements.
Considering converting methods, material tolerances and production controls during development can help ensure that a component designed at prototype stage remains suitable for repeatable commercial manufacture
3. Testing, Verification & Validation
Design verification confirms that design outputs meet specified requirements, while design validation confirms that the finished device meets user needs and its intended use.
The testing required depends on the device and its associated risks. For adhesive components, this may include assessing adhesion strength or evaluating performance under relevant environmental conditions.
This process should reflect how a component will function within the finished device. Results from an individual material may not fully represent its behaviour when combined with other materials, so the test approach needs to account for the intended construction.
Risk management also continues throughout this stage, helping teams identify potential hazards and assess appropriate controls as the design develops.
4. Manufacturing Preparation & Process Validation
A successful prototype must be translated into a repeatable, controlled manufacturing process. Manufacturing preparation involves establishing suitable production methods and controls to ensure components meet their specifications.
For adhesive components, factors such as die-cutting accuracy and material alignment can influence the quality of the finished product. These requirements need to be understood before production begins.
Process validation provides documented evidence that a manufacturing process can consistently achieve its intended results under defined conditions. Production volumes also need consideration; methods used for early prototypes may require adjustment before larger quantities can be manufactured reliably.
BDK supports customers from prototyping through to volume manufacture, helping bridge the gap between design development and production.
5. Regulatory Readiness & Commercial Production
Before a medical device can be placed on the market, its manufacturer must meet the regulatory requirements applicable to the product and its intended market. These responsibilities depend on the project and the parties involved. Medical device manufacturers remain responsible for ensuring that the finished device meets the requirements applicable to it.
Depending on the device, this may involve technical documentation or clinical evaluation. Any changes to materials or manufacturing processes can affect the evidence needed to demonstrate compliance.
Quality management is equally important during production. Manufacturers need appropriate controls to ensure that products continue to meet their specifications, with relevant records maintained throughout the process.
For adhesive components, this may include material traceability and documented manufacturing controls. The specific requirements depend on the component’s function and the wider needs of the finished device.

Supporting Your Medical Device Development Project
Medical device development requires a clear understanding of the product’s requirements and how it will be manufactured. Bringing manufacturing expertise into the process early can help teams assess component designs before committing to production.
For projects involving adhesive components, a specialist manufacturing partner can provide valuable input on material suitability and production feasibility.
BDK works with medical device manufacturers to develop and produce engineered adhesive components to specific requirements. Our services include prototyping, specialist converting and assembly, with support for process validation where required.
