Abstract

---

A microneedle has a proximal end portion and a distal end portion and defines a lumen. The proximal end portion is configured to be coupled to a cartridge to place the lumen in fluid communication with the cartridge. The proximal end portion includes a base surface that is configured to be placed in contact with a surface of a target tissue. The distal end portion of the microneedle includes a beveled surface. The beveled surface defines a tip angle of less than about 20 degrees and a ratio of a bevel height to a bevel width of less than about 2.5.
