ABSTRACT:
A device, system and method deliver an agent to a soft mass, such as an area of the body, and more specifically the brain. One aspect includes creation of one or more channels, tunnels or grooves in tissue using a relatively small diameter, minimally-invasive stylet and then removing the stylet prior to infusion. The stylet-created channels become paths of increased hydraulic conductivity, through which the infusate will tend to flow and produce a predictable infusion pattern. Infusate will be carried into these channels with relatively low resistance, and then infuse outward from these channels into the surrounding tissue. By carefully positioning these channels, one can control and modify the preferred paths and duration of distribution.
