Active implants & Drug Delivery

PEEK-OPTIMA™ polymers for next generation implantable and drug delivery medical devices

Accelerating new medical device design 

The inherent characteristics of PEEK polymers provide exceptional design and processing versatility to overcome the limitations of conventional materials in active implantable medical devices and drug delivery systems

Trends driving innovation in medical devices

Drug delivery & active implantable medical devices have the potential to lower treatment costs, improve patient outcomes and promote an active lifestyle. Finding ways to improve the device or to develop new solutions is challenging – but with the right high performing materials, that journey can be easier. We are here to help you discover what is possible, and how far you can push the boundaries when inventing with PEEK.

Patient comfort

Manufacturers seek new technologies to help support patients with compliance, adherence and increase patient comfort

Wireless technology

Many new AIMD systems communicate wirelessly with the implant and other external equipment, and need to be minimally invasive

Smaller size batteries

Designers want to optimize the performance of ever increasingly miniaturized applications - how can devices be thinner and smaller whilst still retain a long battery life?


Superior biomaterial properties of PEEK-OPTIMA Natural polymer have the potential to improve performance in active implantable medical devices. One of the most dynamic areas in the healthcare industry today are active implantable medical devices (AIMDs). An AIMD is any active medical device that is intended to be totally or partially introduced into the human body for diagnostic or therapeutic purposes, and which is intended to remain in place.


The dielectric properties of PEEK-OPTIMA polymer allow for exceptional performance as an insulator, with minimal interference and minimal loss over changing conditions such as temperature, humidity, and frequency.

Cochlear implants

Lightweight and durable to resist impact, and for continued use over time, even in miniaturised parts found in bone conduction implants.

Artificial heart impeller pump

Ventricular assist devices

PEEK-OPTIMA polymers have proven biocompatibility and resistance to a broad range of chemicals and blood, along with excellent wear resistance - and can be used to develop state-of-the art VAD such as total artificial hearts.
