1. A multilayered tube, comprising:
at least one stretched polymeric material layer comprising a polymer selected from the group consisting of poly(L-lactide) (PLLA), poly(D-lactide) (PDLA), poly(ε-caprolactone) (PCL), polyglycolic acid (PGA), poly(para-dioxanone) (PDO), poly(hydroxybutyrate), poly(hydroxyvalerate), poly(tetramethyl carbonate), poly(ethylene oxide) (PEO), poly(ethylene glycol) (PEG), poly(propylene glycol) (PPG), and copolymers, derivatives and combinations thereof; and
at least one adhesive material layer comprising a polymer selected from the group consisting of poly(ε-caprolactone), poly(trimethylene carbonate), poly(D,L-lactide), poly(L-lactide)-co-ε-caprolactone), poly(L-lactide-co-trimethylene carbonate), poly(ε-caprolactone-co-trimethylene carbonate), poly(ethylene glycol), poly(L-lactide-co-poly(ethylene glycol)), and copolymers, derivatives and combinations thereof, wherein:
the at least one stretched polymeric material layer exhibits at least partial molecular orientation;
the at least one stretched polymeric material layer and the adhesive material layer are comprised in different layers of the tube;
the at least one adhesive material layer adheres adjacent layers of the at least one stretched polymeric material layer to itself or to other layers within the multilayered tube;
the multilayer tube has an orientation profile that is substantially consistent throughout a wall of the multilayered tube.
