SYSTEM AND METHOD FOR DELIVERING FLUID INTO FLEXIBLE BIOLOGICAL BARRIER

摘要

A system and method for delivering fluid into a flexible biological barrier employs a microneedle (12) structure wherein a final position of microneedles inserted into the biological barrier (14) is generally sideways projecting from the delivery configuration instead of the conventional downwards projecting arrangement. The microneedles project from a relief surface (16) which is distinct from a primary biological-barrier contact region (18, 26) of the delivery configuration, and is typically angled upwards away from the biological barrier. During insertion, the contact region is brought into contact with the biological barrier and moved parallel to the surface of the flexible biological barrier so as to generate a boundary (20) between a stretched portion (22) and a non-stretched portion (24) of the barrier.
