Abstract
An automated, and/or semi-automated, sequential drug delivery injector system, where the energy provided to dispense medicament from a plurality of containers or cartridges can be iterated to deliver the medicament(s) in discrete steps, without mixing of the medicament components within the device. A pressurized gas source can drive the flow through a plurality of valves to sequentially dispense a dose, or discrete drugs, from each of the plurality of containers housed within the device. The delivery needle is in fluid communication with a flow path linking the adjacent drug containers when in the nominal state.
Claims20
A drug delivery system comprising:
- a housing configured to hold a first container and a second container, wherein the first container contains a first medicament component and the second container contains a second medicament component;
- a first seal associated with the first container;
- a second seal associated with the second container;
- a fluid communication assembly having a fluidic channel between the first container and the second container, the fluid communication assembly configured to be displaced from a first position to a second position within the housing thereby opening, removing or otherwise piercing the first seal and second seal to provide a fluidic pathway between the first container and the second container;
- at least one stored energy source configured to dispense the first and second medicament components;
- and
- a needle delivery assembly including a delivery needle having a first end and a second end, the first end of the delivery needle in fluid communication with the fluidic channel in the first position.

A drug delivery system comprising:
- a housing configured to hold a first container and a second container, wherein the first container contains a first medicament component and the second container contains a second medicament component;
- a first seal associated with the first container;
- a second seal associated with the second container;
- a fluid communication assembly having a fluidic channel between the first container and the second container, the fluid communication assembly configured to be displaced from a first position to a second position within the housing thereby opening, removing or otherwise piercing the first seal and second seal to provide a fluidic pathway between the first container and the second container;
- a pressurized gas chamber at least partially disposed in the housing and in fluid communication with the first container and the second container;
- an activation mechanism configured to open or otherwise pierce the pressurized gas chamber;
- at least one valve configured to release a portion of pressurized gas that facilitates the dispensing of the first and second medicaments components;
- and
- a needle delivery assembly configured to be in fluid communication with the first and second containers during a delivery phase.
