Dry to Wet Injector

Abstract: 

The present disclosure relates to an apparatus and method for combining a solid particulate with a solvent prior to an injection protocol within an injector device. The solid particulate may be a pharmaceutical compound and the microcapsules contain a solvent for such particulate. Upon application of pressure, the microcapsules may be configured to burst and release the solvent, thereby dispersing and/or partially dissolving the particulate. The injector therefore allows for the use of relatively unstable pharmaceutically active compounds in a device that requires relatively long storage times and the use of pharmaceutical compounds that are relatively stable in the dry state.
