Scientists at New York University Abu Dhabi have developed a novel brain implant capable of precisely delivering drugs to multiple brain regions, opening new pathways for treating neurological disorders. The research findings were published in the latest issue of Journal of Neural Engineering.

This implant, named "Strategic Precise Injection for Regional Liquid Administration" (SPIRAL), is a thin, flexible catheter that can accurately release drugs at multiple sites within the brain. It not only covers broader and more complex brain tissue regions but also maintains the implant’s compact size and minimally invasive characteristics.

The research team noted that neurological disorders often originate in specific brain regions, and existing tools struggle to target these areas precisely. SPIRAL enables simultaneous drug intervention in multiple brain regions without increasing additional risks, potentially revolutionizing treatment models for such disorders.

SPIRAL features meticulously designed openings for controlled drug release. Through advanced computer modeling and extensive experimental validation, the research team confirmed its safety and effectiveness.

Compared to conventional implants, SPIRAL does not trigger more severe inflammatory responses, indicating its suitability for long-term treatment. Additionally, SPIRAL holds promise for advanced therapies such as electrical stimulation, offering new hope for patients with neurological disorders like epilepsy and Parkinson’s disease.
