Abstract
A method and apparatus deliver dry, flowable hemostatic powder into a gas flow stream by gravity delivery within a body of the apparatus. The hemostatic powder is then carried with the gas out of the apparatus into an elongated delivery tube inserted into a patient. Delivery of the powder into the gas flow stream creates a bolus of powder and air which becomes more uniformly distributed as it passes through the elongated delivery tube.
