Abstract
A system for performing an intraparenchymal drug infusion including a pump device, a delivery tube, a sensor, and a processor. The tube is fluidly coupled to the pump device, establishing an infusate pathway from the pump to an infusate exit port of the delivery tube. The sensor is positioned to sense a parameter indicative of pressure in the infusate pathway. Finally, the processor is programmed to generate information indicative of infusate delivery effectiveness of a drug infusion procedure based upon information from the sensor. In some embodiments, the processor generates a net infusion pressure profile, such as a pressure-time curve, and prompts display of the pressure profile to a neurosurgeon for subsequent evaluation of infusate delivery effectiveness.
