Abstract
An improved assembly and method for accurately and safely delivering a drug to a selected intracranial site are disclosed. The assembly ensures delivery of the drug to the selected site by providing a barrier which prevents “backflow” or leakage of the drug. The assembly includes a guide catheter having an inflatable balloon which is able to seal or occlude the tract created by the insertion of the guide catheter into the brain. The guide catheter further includes a passageway which receives a delivery catheter through which the drug is administered to the selected site in the brain. Upon delivery of the drug to the selected site, the balloon may be deflated and the assembly removed.
