26. A device for delivery of a biodegradable micro-needle across a biological barrier, wherein the micro-needle comprises a therapeutically active ingredient and a biodegradable polymer, wherein the device comprises;
-
a. a micro-needle strip comprising a biodegradable micro-needle, and b. a mechanism to cut a selected portion of biodegradable micro-needle corresponding to the selected dose of the biodegradable micro-needle to be delivered;
the mechanism further comprising a main piston and an auxiliary piston for positioning and applying the biodegradable micro-needles to the skin surface;
a roll for loading the micro-needle strip of biodegradable micro-needles;
a cutter for cutting the biodegradable micro-needles;
a flexible wall comprising an opening for discharge of micro-needles and housing holding all the components of the device;
wherein, the micro-needle strips comprising at least one biodegradable micro-needle. - View Dependent Claims (27, 28, 29, 30, 31, 35, 37)

- 32. A method for delivering the biodegradable micro-needle from a device wherein the method comprises (a) setting up the portion of the biodegradable micro-needle corresponding to the dose of the biodegradable micro-needle to be delivered, (b) rotating the main piston by half or one rotation in one direction to cut the portion of the biodegradable micro-needle corresponding to a set dose of biodegradable micro-needle (c) rotating the main piston by half or one rotation for the next operation in the same direction to position the auxiliary piston for the next operation (d) applying force on the main piston to position the biodegradable micro-needle on the flexible wall and to deliver the portion of the biodegradable micro-needle corresponding to a set dose of biodegradable micro-needle on to the skin surface, and (e) a release mechanism to reposition the main piston to its original position.
