A micro-needle () comprising a sharp tip (), an elongated body () and a head () containing at least two parallel independent lumens (), each of said lumens () communicating with a distal side opening () of the head (); said openings () being essentially oriented in a direction which is perpendicular with respect to its lumen () main direction and wherein the distal top end () of said lumen () is in the head () of the micro-needle ().

Multichannel micro-needles

An out-of-plane microneedle manufacturing process comprises the simultaneous creation of a network of microneedles and the creation of a polygonal shaped hat above each microneedle under formation. The process comprises the following steps: providing bridges between the hats, maintaining the bridges during the remaining microneedle manufacturing steps, removing the bridges, together with the hats, when the microneedles are formed.
