| 1. An apparatus for delivering a biologically active material to a body lumen comprising:
a catheter having a distal portion and a proximal portion;
a balloon, having a balloon wall including a layer defining an outer surface and an inner surface, disposed at the distal
portion of the catheter; and
a plurality of micro-needles disposed upon the outer surface of the balloon,
wherein the micro-needles are capable of contacting the body lumen to deliver the biologically active material to the body
lumen; and the micro-needles are disposed upon a plate, which is attached to the inner surface of the layer of said balloon
wall in a manner such that the micro-needles project through the layer of the balloon wall.
