Apparatus and Methods for Drug Delivery Using Microneedles |
| 摘要 |
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. |

1. An apparatus, comprising:
a microneedle having a distal end portion and a proximal end portion, and defining a lumen, the proximal end portion configured to be coupled to a cartridge to place the lumen in fluid communication with the cartridge, the proximal end portion including a base surface configured to contact a surface of a target tissue, the distal end portion including a beveled surface, the beveled surface defining a first bevel angle and a second bevel angle different than the first bevel angle. |
