초록 ▼

A fluid pathway is provided with a flow controller in at least a portion of its length wherein the flow controller comprises an active surface capable of influencing the fluid flow through the fluid pathway, the configuration of the active surface conforming to at least one logarithmic curve conform

대표청구항 ▼

1. A duct comprising: an inlet for receiving the fluid;an outlet for expelling the fluid; andan intermediate fluid pathway between the inlet and the outlet, the intermediate fluid pathway excluding a substantially right angle bend and including a curvature between the inlet and the outlet, the curvature inducing vortical flow that reduces turbulence in the fluid flow as the fluid traverses the intermediate fluid pathway, and wherein the curvature substantially unfolds at a constant order of growth when measured at equiangular radii between the inlet and the outlet. 2. The duct of claim 1 wherein the curvature is configured to facilitate a change of direction in the flow of a fluid. 3. The duct of claim 1 wherein the curvature comprises a spiral twist between the inlet and the outlet. 4. The duct of claim 1 wherein the curvature comprises a helical twist between the inlet and the outlet. 5. The duct of claim 4 wherein the duct comprises a cardiovascular stent. 6. he duct of claim 1 wherein the curvature is substantially in the form of a shell configuration from the phylum Mollusca, class Gastropoda, genus Volutidae. 7. The duct of claim 6 wherein the duct comprises a fluid flow controller for reducing turbulence in fluid flow. 8. A duct comprising: an inlet for receiving the fluid;an outlet for expelling the fluid; andan intermediate fluid pathway between the inlet and the outlet, the intermediate fluid pathway excluding a substantially right angle bend and including a curvature between the inlet and the outlet, the curvature inducing vortical flow that reduces turbulence in the fluid flow as the fluid traverses the intermediate fluid pathway, and wherein the curvature is substantially in the form of a shell configuration from the phylum Mollusca, class Gastropoda, genus Volutidae. 9. The duct of claim 8 wherein the duct comprises a fluid flow controller for reducing turbulence in fluid flow.
