Hemostatic powder delivery devices and methods

The present invention is directed to a device for expressing a hemostatic powder having an elongated reservoir with a manual air pump, such as a bellows, at a proximal end and an expression port at a distal end. A porous filter is slidably disposed within the reservoir between the bellows and the plunger and the expression port, and a spring is disposed within the reservoir between the air pump and the plunger. The powder is disposed within the reservoir between the porous filter and the expression port, and the pump is in fluid communication with the expression port through the porous filter and through the powder.
