Abstract
An applicator and method for dispensing a stream of a particulate and a fluid from a cannula and a mixing tip. The mixing tip includes a housing having an inlet, an outlet, and a mixing channel extending therebetween. A fin is positioned within the housing and extends along at least a portion of the mixing channel. The fin spirals about the mixing channel from the inlet toward the outlet for mixing and distributing the particulate generally uniformly within the fluid. The stream is directed into the mixing channel of the mixing tip and spiraled along the fin within the mixing channel. The spiraling increases turbulence and mixes the stream into a mixed stream of particulate and fluid. The mixed stream is discharged from the mixing tip for being dispensed onto an anatomical site.
