Claim:
1. A system for delivering a substance to a patient, the system comprising: a trajectory guide configured to be secured to a body of the patient; a cannula supported by the trajectory guide, the cannula comprising a cannula body defining at least one longitudinally extending lumen, an inlet port, and at least one exit port, wherein the trajectory guide provides X-Y adjustment and pitch and roll adjustment for the cannula; a substance delivery device, comprising: a syringe in fluid communication with the tubular body proximal end via first flexible tubing having a connector that is matingly and removably secured to the tubular body proximal end connector, wherein the syringe and the first flexible tubing contain the slave fluid, wherein activation of the syringe to cause the slave fluid to move the diaphragm in the second direction causes a substance to be loaded within the tubular body between the diaphragm and the tubular body distal end; wherein the at least one longitudinally extending lumen of the cannula is fluidly connected to the tubular body distal end via second flexible tubing, and wherein the cannula is adapted to transfer the substance from the tubular body to a selected location in the patient via the at least one exit port upon activation of the syringe to cause the slave fluid to move the diaphragm in the first direction.
