Encapsulation

Protection at the Heart of Tomorrow's Implants

Encapsulation: A Key Challenge for the Implants of the Future

Active implantable medical devices must operate for long periods of time in a particularly demanding environment.

Encapsulation must therefore protect the components from moisture and bodily fluids, while meeting requirements for biocompatibility, mechanical strength, and reliability.

The choice of materials and encapsulation design depends directly on the device’s functions. Titanium, PEEK, or hybrid solutions may be considered, depending on the project’s constraints, the integrated components, and electromagnetic transmission requirements.

Encapsulation must therefore be considered from the earliest stages of design in order to achieve the best balance between protection, performance, integration, and durability.

Developing an encapsulation solution requires taking into account all the constraints related to the device and its operating environment.

Cisteo MEDICAL and Tame-Care are working on various aspects, including:

Biocompatibility of the Materials Used
Waterproofing and protection against bodily fluids
Mechanical Strength and Durability
Integration of Electronic Components
Electromagnetic Transmission for Wireless Systems
Thermal Management of Implanted Components
Compatibility with Manufacturing Processes
Reliability of the encapsulation over the implant's lifespan

The goal is to develop an encapsulation solution tailored to the architecture and specific functions of each medical device.

Titanium offers excellent mechanical strength and high resistance to the physiological environment.

It is a solution particularly well-suited for implants that require airtight and durable encapsulation.

One of the key advantages of PEEK is that it is transparent to electromagnetic waves, which can facilitate the integration of wireless communication or power transfer functions.

A combination of materials can make it possible to simultaneously meet the various requirements of the implant.

This approach makes it possible to combine protection, hermetic sealing, electronic integration, and the transmission of signals or energy, depending on the device's architecture.
