Medical device R&D is a longer and more structured process than the phrase might suggest, involving years of iterative design, testing, and documentation before a new catheter, stent, or interventional system reaches a clinician's hands. Unlike consumer product development, medical device R&D operates under strict design control requirements intended to catch problems early and ensure the finished device performs as intended and as documented in its Instructions for Use (IFU). Walking through the stages a device typically passes through inside an R&D center illustrates why bringing a genuinely new device to market takes considerably longer than refining an existing one.
How Does a Device Concept Become a Design Input?
Every device R&D project begins with defining design inputs — the clinical, mechanical, and regulatory requirements a device must satisfy, drawn from clinician feedback, competitive analysis of existing device categories, and identified gaps in current treatment options. Biomedical and mechanical engineers translate these inputs into specific, testable design outputs: dimensions, materials, mechanical performance targets, and manufacturing specifications. This stage typically involves close collaboration between engineering teams and clinical advisors, since a device that meets its mechanical specifications but fails to address the underlying clinical need will not succeed in verification and validation testing later in the process.
What Happens During Verification and Validation?
Verification confirms that a device meets its design outputs — for example, that a catheter shaft achieves its specified kink resistance or that a stent meets its target radial force — typically through bench testing under controlled laboratory conditions. Validation, a distinct step, confirms that the finished device actually meets the user's needs and intended use, which may involve simulated use testing, animal studies where appropriate, or other methods suited to the device category and risk classification. Both verification and validation activities must be documented within the device's design history file, since this documentation becomes essential evidence during regulatory review and any future quality investigation.
How Do Design Controls Lead to a Finished IFU?
As a device design matures through verification and validation, the R&D team works alongside regulatory and quality functions to prepare the technical documentation required for European market authorization under the applicable European medical device regulations (for devices intended for the European market) and to draft the Instructions for Use, the document that specifies indications, contraindications, warnings, and directions for clinical use. The IFU is not an afterthought — its content is derived directly from the verified and validated design and intended use established during R&D, which is why regulatory and quality teams are typically involved throughout development rather than only at the final submission stage. This integrated approach — engineering, clinical input, and regulatory documentation developing together — is intended to reduce the risk of late-stage design changes that can delay market entry.
What Does This Process Look Like at Scale?
As company-stated, INVAMED operates a dedicated R&D center, INVAcenter, staffed by more than 40 biomedical engineers focused on new device design and iteration, supported by a broader manufacturing organization of more than 200 specialists across its Ankara, Turkey campus. The company has stated that this R&D investment has contributed to a portfolio of more than 100 international patents across six continents and more than 150 devices spanning 23 product categories.

How long does it typically take to bring a new interventional device from concept to market?
Timelines vary considerably by device complexity and risk classification, but original device development often takes multiple years when accounting for design iteration, verification and validation testing, and regulatory submission and review. Modifying an existing platform is typically faster than developing an entirely new device category.
