Abstract
A device for aerosolizing a liquid includes a chamber having a deformable wall which expands and contracts as fluid is delivered and expelled from a fluid chamber. The chamber is partially bounded by a vibrating structure having holes therein for expelling the fluid. In another aspect, the invention provides exemplary aerosolization apparatus and methods for aerosolizing a substance. A liquid is transferred from a first chamber into a second chamber having a substance that is in a dry state to form a solution. The solution is then transferred from the second chamber and onto an atomization member. The atomization member is operated to aerosolize the solution.
