A needle for atraumatic injection of particles of fat into the body of a patient is disclosed. The needle contains a through-bore which extends continuously between the proximal, intermediate, and distal portions thereof. The distal end of the needle has a generally conical configuration terminating in a relatively blunt, smooth surface. The needle is characterized by a plurality of radial ports equally spaced about the circumference of the intermediate portion adjacent the distal portion, and the cross-sectional area of each port corresponds with the cross-sectional area of the through-bore. When the needle is inserted into a given location below the skin of the body of a patient, and when particles of fat are delivered to the through-bore at the needle proximal portion, the particles are injected into the body via the ports.
