A device for delivering biological agents includes a cannula for insertion into tissue having a distal end with a notch formed therein. A flexible membrane extending across the cannula notch has a surface for supporting a quantity of a biological agent. A temperature controlled fluid is disposed within the cannula for displacing the support surface of the membrane laterally with respect to the cannula to deliver the biological agent with precision to a tissue site or body cavity.
