Abstract: Elastomeric bypass grafts (EBG) described herein can be pre-stretched and are able to accommodate limb flexion-induced or organ-induced deformations without producing excessive tortuosity or stresses. In comparison to known grafts, EBGs demonstrate significantly less tortuosity when used for lower extremity repair during limb flexion, and improved flow patterns within the grafts. Longitudinally pre-stretched EBGs described herein improve hemodynamics and may produce better healing responses in the harsh mechanical environment of the lower limbs, compared to known grafts.

Abstract: A stent-graft apparatus includes a membrane configured to exhibit one or more mechanical properties in a range corresponding to a range for the one or more mechanical properties for human vascular tissue, and a scaffold coupled to the membrane, the scaffold including one or more struts.
