Device and a system for delivery of biological material

Abstract

The present invention provides a device and a system for the delivery of biological material across the biological tissue. The device may be for the programmed delivery of biological material through a needle or a micro-needle or micro-needles or biodegradable micro-needles.

26 . 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 re-position the main piston to its original position. 
     
     
         27 . The method as claimed in  claim 26 , wherein the portion of the biodegradable micro-needle corresponding to the selected dose includes the vertical movement of the micro-needle strip comprising of biodegradable micro-needles by a known mechanism. 
     
     
         28 . The method as claimed in  claim 26 , wherein the application of force on the main piston either for positioning the biodegradable micro-needle or delivery on to the skin surface uses energy stored in a spring or any other known mechanism. 
     
     
         29 . The device for delivery of biodegradable micro-needle and method of delivery claimed in  claim 26  is as described in the description and shown in  FIG. 3  and  FIG. 4 .
