| Outline of Final Research Achievements |
Recently, we have been working towards CNS (central nervous system) drug delivery system that enables effective distribution of the infusate. Aiming at improved and stable drug delivery system, we developed ultrasound facilitated drug delivery (UFD) device that achieve improved distribution in brain parenchyma. In this study, in order to improve the system, we developed pressure-controlled microinfusion pump. We demonstrated that our system enabled constant pressure delivery within +/- 1mmHg pressure range. Second generation UFD device was also fabricated for stable delivery. Subsequently, to prove that our device is applicable to multiple CNS diseases, we attempted to deliver therapeutic agents to epilepsy model, spinal disease model, and Alzheimer disease model. Anti-epileptic agents worked in epilepsy model, chemotherapeutic drug worked in spinal tumor model. Both of these headed for publication of the literature.
