A method comprises applying a thermal activation signal to a conduit comprising a shape memory polymer, causing a change in at least one property of the shape memory polymer, and regulating fluid flow through the conduit by the change in the at least one property of the shape memory polymer. A conduit comprises a shape memory polymer in an amount effective to regulate fluid flow through the conduit by a change in at least one property of the shape memory polymer caused by application of a thermal activation signal. The conduits and methods disclosed herein may find use as drinking utensils, respirator tubes, pump intake tubes, motor vehicle cooling system bypass hoses, motor vehicle engine oil filter bypass hoses, or motor vehicle powertrain fluid circulation hoses.

The invention claimed is: 1. An intermediate conduit section formed of a single layer wall, presenting a first longitudinal profile and a first open cross-sectional flow area, and comprising a shape memory polymer in an amount effective to reconfigure the profile and area so as to present a second profile and open area and thereby regulate fluid flow through the conduit section, by a change in at least one property of the shape memory polymer caused by application of a thermal activation signal. 2. The conduit section of claim 1, wherein the shape memory polymer comprises polyphosphazenes, poly(vinyl alcohols), polyamides, polyester amides, poly(amino acid)s, polyanhydrides, polycarbonates, polyacrylates, polyalkylenes, polyacrylamides, polyalkylene glycols, polyalkylene oxides, polyalkylene terephthalates, polyortho esters, polyvinyl ethers, polyvinyl esters, polyvinyl halides, polyesters, polylactides, polyglycolides, polysiloxanes, polyurethanes, polyethers, polyether amides, polyether esters, polystyrene, polypropylene, polyvinyl phenol, polyvinylpyrrolidone, chlorinated polybutylene, poly(octadecyl vinyl ether) ethylene vinyl acetate, polyethylene, poly(ethylene oxide)-poly(ethylene terephthalate), polyethylene/nylon (graft copolymer), polycaprolactones-polyamide (block copolymer), poly(caprolactone) dimethacrylate-n-butyl acrylate, poly(norbornyl-polyhedral oligomeric silsequioxane), polyvinyl chloride, urethane/butadiene copolymers, polyurethane block copolymers, styrene-butadiene-styrene block copolymers, and combinations comprising at least one of the foregoing. 3. The conduit section of claim 1, wherein the change in at least one property comprises a change in elastic modulus, a shape, a dimension, a shape orientation, a phase of matter, or a combination comprising at least one of the foregoing properties. 4. The conduit section of claim 1, wherein regulating fluid flow through the conduit section includes collapsing or expanding the conduit section. 5. A drinking utensil including a cylindrical section presenting a first longitudinal profile and a first open cross-sectional flow area and comprising a shape memory polymer in an amount effective to reconfigure the profile and area so as to present a second profile and open area and thereby regulate flow of a drinkable fluid through the drinking utensil, by a change in at least one property of the shape memory polymer caused by application of a thermal activation signal.
