Abstract:

The present invention is a method for releasing an active agent into a use environment by disposing this active agent within the lumen of a population of tubules. and disposing the tubules into a use environment, either directly or in some matrix such as a paint in contact with the use environment. The tubules have a preselected release profile to provide a preselected release rate curve. The preselected release profile may be achieved by controlling the length or length distribution of the tubules or by placing degradable endcaps over some or all of the tubules in the population, or by combinations of these methods. The invention is also a population of tubules having a preselected release profile to provide a preselected release rate curve.
