Abstract:
A catheter assembly for delivering a drug to a selected site in a patient's brain, comprising:intracranial positioning means for providing a passageway within the brain, the intracranial positioning means having proximal and distal ends and a lumen extending from the proximal end to the distal end and terminating at an inflatable balloon; a stylet positioned in the passageway for insertion into the brain; and a delivery catheter received within the passageway after removal of the stylet, the delivery catheter for delivering the drug to the selected site in the brain, the delivery catheter having a first opening near a first end, a second opening near a second end and an axial bore extending therebetween, whereby the balloon can be inflated to seal a tract created during insertion of the intracranial positioning means into the brain so that the drug is fully absorbed by brain tissue at the selected site.
