Maximal resection and functional preservation, are often conflicting, but are both important factors to improve patient’s quality of life. Pulsed jet system is designed to achieve this goal by removing lesions without impairing small diameter vessels (100 μm - ). Standardization and specialization of surgical procedures is expected to achieve more easily compared to conventional surgical device using pulsed jet system. We have already reported significant increase of tumor removal rate, significant reduction of intraoperative blood loss and operation time in difficult lesions in the vicinity of sella turcica and skull base through expanded transsphenoidal approach. The system can eject small amount ( - 2 μl) of high speed liquid (- 50 m/s) for minimally invasive surgery, such as endoscopic, catheter, and microscopic surgery. The system is now under stage to expand clinical application outside the field of neurosurgery, and we are expecting new collaboration who can deal with increasing safety, effectiveness, differentiation from conventional instruments, accessibility.
