Patent ID: 8728032

Claim:
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 and has a reservoir containing the therapeutic agent; a pressure source having pressurized fluid, the pressure source in selective fluid communication with at least a portion of the reservoir of the container, wherein fluid from the pressure source is directed through the first region of the container in a direction towards the second region of the container, wherein the fluid is at least partially redirected to urge the therapeutic agent in a direction from the second region of the container towards the first region of the container and subsequently towards the target site, wherein, during use when at least some of the pressurized fluid is directed through the container in a hand-held orientation, the first region of the container is disposed vertically above the second region of the container; and 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 and into the reservoir of the container, 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.
