Patent attributes
An allergen-loadable microneedle cartridge is disclosed. The cartridge includes at least one substrate, a plurality of microneedles in a microneedle layout protruding from at least one substrate, and fillable allergen sites corresponding to the microneedle layout. The fillable allergen sites and microneedle layout are configured such that the microneedles can penetrate subject skin and deliver pharmacologically active doses of allergens in a minimally invasive process. A planar allergen filling system for loading the allergen-loadable microneedle cartridges is also disclosed. The system has a loading section with spaced-apart allergen loading sites that correspond to the microneedle layout of the microneedle cartridge. Filling wells having allergen deposition areas larger than the allergen loading sites transfer deposited allergen to the allergen loading sites through capillary channels. The allergen-loadable microneedle cartridge is loaded by contacting its fillable allergen sites with the loading section of the planar allergen filling device.
