When developing an active implantable device, the electronic system is rarely the most visible part of the project. Yet it determines almost everything that matters: how long the device lasts, how small it can be, whether it will pass regulatory review, and ultimately whether it is safe to implant in a human body. Understanding these […]

The pressure on early neuro lead projects Engineers and project managers in early-stage neuromodulation work under a consistent set of constraints: limited resources, tight timelines, and regulatory requirements that cannot be deferred. Custom electrode leads are needed quickly, but conventional manufacturing paths depend on custom tooling, long procurement cycles, and supplier relationships that take time
Custom Neuro Leads in 8 Weeks: Why CorTec Is the Expansion of Your Team Read More »
The lead is the starting point of every active implant system. Its geometry, materials, and manufacturing quality set the constraints for encapsulation, electronics, and regulatory documentation alike. Bridging the distance between a validated lead and a complete active implant system is where most development programs slow down. It demands expertise that spans disciplines most organizations keep separate: the mechanics of implantable

Active implant systems are the foundation of modern neurotechnology. It enables precise, bidirectional communication with the nervous system, driving powerful BCIs and Medical Devices in Neuromodulation, advancing therapy, research, and assistive technologies. Its impact on data quality, adaptability, and clinical effectiveness makes it a core technology in neurotech. Unlike isolated devices, integrated systems continuously interact

Bringing a neuromodulation medical device to clinical reality is rarely just engineering. It is a long, tightly interdependent chain of decisions: electrode design and materials, implantable electronics and embedded software, system integration, biocompatibility testing, and regulatory documentation, each one affecting the others. At CorTec, we bring proven end-to-end expertise to address this complexity across every

We are again featured in the latest edition of Open Access Government – more specifically our Brain Interchange System and our way to Stroke Rehabilitation. Our Goal: enhancing the plasticity and enabling the patient to recover after a stroke. One method to achieve the enhancement of plasticity is electrical stimulation of the brain. Fundamental studies

A group of authors from the University of Bordeaux has assessed the state of the art in neuroprosthetics in a whole range of applications – from sensorimotor to cognitive functions. The results of their analysis are now available in a comprehensive review in Communications Biology. As the authors describe, the first attempts for neuroprosteses were

The vagus nerve is one of the biggest cranial nerves. It interconnects the brain with almost all internal organs, including the heart, the respiratory tract, the kidney, and the digestive tract. It mediates important reflexes for autonomic functions and modulates a wide range of body functions, making it an attractive target for bioelectronic interventions. On

About half of the patients afflicted by a stroke permanently suffer from chronic deficits in arm and hand movements. These deficits are not ameliorated by classical physiotherapy and severely affect quality of life. New therapies are urgently needed. We recently reported on an NIH project with Professor Ojemann from the University of Washington at Seattle,
