1. A system suitable for delivering a therapeutic agent to a target site, the system comprising: a container for holding the therapeutic agent, wherein the container comprises first and second regions,wherein the first region houses the therapeutic agent in a pre-delivery state, and wherein the first region comprises an outlet to the target site,wherein the second region is separated from the first region by a platform positioned within the container, the platform forming a substantially fluid tight seal with an inner surface of the container,wherein the therapeutic agent is retained above the platform when the system is in a handheld position and there is fluid communication through the platform between the first and second regions; anda pressure source having pressurized fluid, the pressure source in selective fluid communication with at least a portion of the container,wherein fluid from the pressure source is directed from the second region of the container into the first region of the container via the platform to urge the therapeutic agent in a direction from the second region towards the outlet of the first region and towards the target site. 2. The system of claim 1 further comprising a housing configured to securely retain the container and the pressure source, wherein the housing is adapted to be held in a user's hand in the handheld position. 3. The system of claim 1 further comprising an orientation device for indicating a vertical orientation of the container when held in a user's hand. 4. The system of claim 1 further comprising a cap secured to the first region of the container, the cap having an inlet port and an outlet port, wherein the fluid from the pressure source is directed through the inlet port of the cap, and wherein the fluid is redirected within the container to urge the therapeutic agent through the outlet port of the cap. 5. The system of claim 1 further comprising an inlet tube disposed at least partially within the container, the inlet tube having a first end positioned near the first region of the container and a second end positioned near the second region of the container, wherein the fluid from the pressure source flows through the inlet tube in the direction from the first region to the second region. 6. The system of claim 5 wherein the second end of the inlet tube comprises at least a 90 degree curvature to redirect fluid flow in a direction from the second region of the container towards the first region of the container. 7. The system of claim 5 further comprising a u-shaped tube coupled to the second end of the inlet tube, wherein the u-shaped tube is configured to redirect fluid flow in a direction from the second region of the container towards the first region of the container. 8. The system of claim 5 further comprising an outlet tube disposed at least partially within the container, the outlet tube having first and second ends, wherein fluid exiting the second end of the inlet tube urges the therapeutic agent into the second end of the outlet tube and towards the first end of the outlet tube. 9. The system of claim 8 wherein the second end of the outlet tube is spaced away from the second end of the inlet tube. 10. The system of claim 8 further comprising a flow assembly having an inlet, and outlet, and at least one opening disposed therebetween, wherein the inlet of the flow assembly is coupled to the second end of the inlet tube, the outlet of the flow assembly is coupled to the second end of the inlet tube, and the at least one opening is sized to receive the therapeutic agent when fluid passes between the inlet and the outlet of the flow assembly. 11. The system of claim 1 further comprising a pressure regulator valve disposed between the pressure source and the container. 12. The system of claim 1 wherein the therapeutic agent comprises a powder.
