Patent ID: 8365725

Claim:
A method of deagglomerating dry powder in a dry powder inhaler, comprising: generating a dry powder and air flow pattern having flow vortices in response to user inspiratory effort using at least one turbulence promoter that extends across at least a portion of an inspiratory flow path that is spaced apart from and downstream of a drug containment system comprising dry powder, the at least one turbulence promoter comprising a mesh body of a malleable material that cooperates with a wall of the inhaler to be held in the inhaler, the mesh body configured to generate at least some flow vortices having an axis of rotation that extends axially in an inspiratory flow direction in the inspiratory airflow path and at least some flow vortices having an axis of rotation that is substantially perpendicular to the inspiratory flow direction to thereby facilitate deagglomeration of the dry powder without trapping undue amounts of the dry powder in the inhaler.
