Convection-enhanced delivery (CED) is a bulk flow–driven process. Its properties permit direct, homogeneous, targeted perfusion of CNS regions with putative therapeutics while bypassing the blood-brain barrier. Development of surrogate imaging tracers that are co-infused during drug delivery now permit accurate, noninvasive real-time tracking of convective infusate flow in nervous system tissues. The potential advantages of CED in the CNS over other currently available drug delivery techniques, including systemic delivery, intrathecal and/or intraventricular distribution, and polymer implantation, have led to its application in research studies and clinical trials. The authors review the biophysical principles of convective flow and the technology, properties, and clinical applications of convective delivery in the CNS.

Convection-enhanced delivery is a means to deliver therapeutic agents directly into brain tissue for the treatment of brain tumors and other disorders of the central nervous system. Unfortunately, recent clinical trials have demonstrated limited efficacy of this procedure and suggested that one of the main obstacles is poor distribution of the infused agent [1].

Convection-enhanced delivery (CED) is a means to deliver therapeutic agents directly into brain tissue for the treatment of brain tumors and other disorders of the central nervous system, such as Parkinson’s disease. Recent clinical trials have shown limited efficacy of this procedure, with poor distribution of the infused agent being the primary obstacle [1]. One of the challenges with improving the distribution is the effect of backflow, in which the infused fluid preferentially flows along the outside of the catheter toward the surface of the brain rather than through the tissue toward the desired region for delivery.
