1. A vascular bypass graft, comprising:
an elongate tubular graft made of an elastomeric material that comprises a network of nanofibers arranged to cause the tubular graft to exhibit non-linear elastic compliance in response to increasing longitudinal tensile loads;
a first pre-stretch regulator coupled to a first end portion of the tubular graft and a second pre-stretch regulator coupled to a second end portion of the tubular graft; and
one or more wings extending laterally from the tubular graft.
