Microneedle Lidocaine Delivery

Developed a novel microneedling-based lidocaine delivery device to enable rapid, uniform local anesthesia with minimal patient discomfort. Led the design of a single-use cartridge system featuring a hollow, adjustable-depth microneedle array fabricated from biocompatible polymer (PLA/PETG), integrating a modular fluid reservoir. Created preventative-maintenance protocols and standardized hardware cartridges for components subject to wear, vibration, or thermal cycling, reducing downtime and ensuring consistent performance.

I collaborated with surgical fellows and medical students to validate fluid distribution and anesthetic penetration, refining microchannel dimensions and actuation force through iterative prototyping. Documented every design iteration in a revision-controlled bill of materials. The resulting system demonstrated faster onset times and more uniform lidocaine diffusion compared to traditional injections, streamlining clinical workflows and enhancing patient experience.

The project is still ongoing, once it is finished the report will go here.
