The microneedle has a proximal end portion a distal end portion and a hub portion between the proximal end portion and the distal end portion. The proximal end portion is configured to be coupled to a medicament container, such as, for example a syringe. The portion of the lumen within the proximal end portion has a first diameter. The distal end portion is configured to pierce a target tissue. The portion of the lumen within the distal end portion has a second diameter smaller than the first diameter. The hub portion includes a surface configured to contact the target tissue when the distal end portion is disposed with the target tissue.
