Image Guided Local Drug Delivery for Central Nervous System Disorders

Features and Uniqueness
  • Effective drug delivery to central nervous system is promising as a new therapeutic strategy against various central nervous system disorders. However, it represents a challenge because systemic delivery is always hindered by blood brain barrier, and local delivery cannot be effective because of the restricted distribution. Recently, local drug delivery system that can achieve robust distribution of the infusates by maintaining a pressure gradient at the tip of the infusion catheter during infusion has developed. Although this method is promising, there still exist several problems as loss of infusates by backflow through catheter tract or inconsistent distribution. We recently developed a method to deliver agents with this method under MRI guidance, and now performing clinical trial to treat recurrent gliomas.
Practical Application

Focal central nervous system disorders such as tumor, epilepsy, and parkinson's disease can be the target for application of this technique. Developments of the new catheters and pre-infusional similation systems are on their way. We are searching for effective collaborative research in this field.
