Abstract
Summary The MINOP project involves the development of microsystems technology for use in minimally invasive neuro-surgical operation techniques. New methods for cranial endoscopy have been developed in association with seven partners from medicine, technology and industry. Some of these methods have already been put into clinical operation. Methods being developed include: two wavelength laser (setup and tests on a model); biportal endoscopic approaches; endoscope-assisted techniques; deflectable instruments, based on Nitinol (nickel/titanium alloy); micro-technologically manufactured endoscope lenses; and fluid-controlled flexible endoscopes.
