Their expertise

Mechanical engineering & microtechnology

Cisteo MEDICAL places precision mechanics at the core of medical device development, designing miniaturized, robust, and durable systems. Its mechatronics design office optimizes product architecture, while micromechanics and prototyping accelerate validation and industrialization.

Biocompatible materials

Cisteo MEDICAL masters key medical-grade materials, including nitinol for implantable structures, silicone for biocompatible components, and polymers for encapsulation. This expertise ensures biocompatibility, mechanical strength, and reliable device performance in demanding physiological environments.

Encapsulation

Cisteo MEDICAL develops advanced encapsulation solutions for active implants, including high-precision laser welding in cleanroom environments, leak testing, and hermetic housing assembly. This expertise, particularly with titanium enclosures, ensures robust sealing, electronic protection, and long-term implant reliability.

Industrialization & production

Cisteo MEDICAL manufactures and assembles medical devices in ISO 5 and ISO 7 cleanrooms, ensuring sterility and compliance. The company masters design for manufacturing, process validation (IQ/OQ/PQ), and the production of prototypes, pilot runs, and fully integrated systems.

The expert in implantable and miniaturized medical devices

Cisteo MEDICAL supports manufacturers in developing medical devices with high mechanical and material constraints, particularly in active and non-active implants and minimally invasive surgery.

Its expertise in microtechnologies, biocompatible materials, and encapsulation processes makes it a key partner for projects requiring reliability, miniaturization, and long-term performance.

Certifications

At Cisteo MEDICAL, quality and regulatory compliance are integrated from the design phase and throughout the entire development of medical devices.

The company is ISO 13485 certified, ensuring a quality management system that meets medical device requirements from design to manufacturing, including active implantable devices. It is also FDA registered.

Thanks to the DIAG Medical Device accreditation from Bpifrance, Cisteo MEDICAL enables its clients to benefit from enhanced regulatory support that is partially subsidized.

The company therefore supports its partners in structuring their regulatory strategies, preparing technical documentation, and securing access to international markets.
