ABSTRACT:
A flow assembly has a hollow housing including a lumen extending from a proximal aperture to a distal aperture. The flow assembly can have a first set of blades including at least one first blade disposed within the lumen, wherein the at least one first blade extends from the housing and can be positioned between the proximal aperture and the distal aperture. The flow assembly also has a second set of blades including at least one second blade disposed within the lumen, wherein the at least one second blade extends from the housing and can be positioned between the at least one first blade and the distal aperture. Also, the flow assembly can have a central passageway substantially free of blades extending from the proximal aperture to the distal aperture.
