The present embodiments provide systems and methods suitable for delivering a therapeutic agent to a target site. A container holds the therapeutic agent and a pressure source has pressurized fluid in selective fluid communication with at least a portion of the container. A catheter, in fluid communication with the container, has a lumen sized for delivery of the therapeutic agent to a target site. In one embodiment, a diameter of particles of the therapeutic agent is in a range of between about 1 micron to about 925 microns, a mass of the particles of the therapeutic agent is in a range of between about 0.0001 mg to about 0.5 mg, a ratio of an inner diameter of the catheter to the diameter of particles is at least 4:1, and a regulated pressure of the pressurized fluid is between about 0.01 psi to about 100 psi.

A container for medical liquids comprises an inner container having a distal end and a proximal end, a first porous separating element being arranged at the proximal end, the first porous separating element delimiting a holding volume for holding a medical liquid, and comprising an outer container, in which the inner container is arranged with the proximal end and with at least portions of the holding volume. The outer container extends around the inner container gas-tight such that a gas under positive pressure can be arranged in a peripheral volume arranged between an outer surface of the inner container and an inner surface of the outer container. An outlet channel section is connected to the distal end of the inner container. At least portions of the outlet channel section are arranged outside of the outer container. A valve device can be arranged in the outlet channel section, which valve device is designed, in an open position, to open a fluid connection between a distal outlet opening of the outlet channel section and the holding volume and, in a closed position, to block the fluid connection between the distal outlet opening and the holding volume.

A fluid dispensing device is provided for dispensing a measured amount of fluid into a living organism. The device includes a rigid fluid reservoir closed by a septum for use in a fluid dispensing device for dispensing a measured amount of fluid into a living organism, wherein the device has a main housing enclosing the operative components of the device, the said fluid reservoir located within the main housing, an injection assembly including a needle, and a trigger mechanism. The needle has a first end adapted to piercing the septum and pushing the septum into the reservoir so that the septum acts as a piston, expelling the fluid through the needle, and a second end adapted to injecting the fluid into the living organism.

The present disclosure relates to a portable pressure container for driving a medical device. The container includes a pressure housing confining an interior volume and a pressure outlet extending through the pressure housing. The interior volume comprises a liquid storage portion and a gas storage portion. The liquid storage portion and the gas storage portion are in flow connection with each other. The liquid storage portion is configured to store a liquid phase of a driving medium. The gas storage portion is configured to store a gas phase of the driving medium. The pressure outlet is only in flow connection with the gas storage portion.
