The object
Per Gisle Djupesland invented a breath-powered nasal drug-delivery device that couples a patient exhalation with an engineered delivery path and nozzle. The physical system is designed to reach targeted nasal regions more reliably than a conventional spray, providing a product platform for medicines where deposition matters.
What Per did
Invented a breath-powered precision device for directing medicine through the nasal cavity.
Why it matters
The technology made breath-powered, bidirectional nasal delivery a distinctive physical alternative to conventional pump-spray dosing.

The Norwegian business directory Proff reports Djupesland as both managing director and board chair of Nesensia AS, with 2025 financial figures; this is direct recent evidence of an operating role.
