ABSTRACT:
A drug delivery system includes a container having proximal and distal ends and a rapidly openable divider, replaceably disposed within the container to separate the container into a proximal chamber that is selectively gas impermeable and able to receive a pressurized gas and a distal chamber having an opening at a distal end thereof. A membrane is disposed between the opening in the distal chamber of the container and a biologic material, such as a patient's skin, treated with a medicament. In operation, rapid opening of the divider causes a shock wave to be generated and transmitted through the opening in the distal chamber to impinge on the membrane which transfers the shock wave to the biologic material. The system may further include a drug housing mountable in a fluid tight manner on the biologic material and an optional sealing element by which the fluid tight seal is created.
