1. A vascular tissue repair device, comprising:
a generally tubular intraluminal scaffold having a luminal surface, an abluminal surface, and a wall thickness between the luminal surface and the abluminal surface, the intraluminal scaffold being composed of nonwoven fibers made of a biodegradable and/or bioresorbable material, the luminal surface being comprised of substantially curvilinear nonwoven fibers and the abluminal surface comprising substantially linear fibers and the abluminal surface being adapted to face and be in apposition to a luminal wall of the vascular tissue;
wherein the nonwoven fibers in the wall thickness between the abluminal surface and luminal surface exhibit a transition gradient between substantially curvilinear and substantially linear throughout the wall thickness; and
wherein the generally tubular intraluminal scaffold has an average porosity capable of cellular permeability.
