Abstract:
An expandable supportive endoluminal graft, comprising:a tubular supporting component with a longitudinal axis, an internal surface, and an external surface, said tubular supporting component having a network of land areas with open areas defined between said land areas, said tubular supporting component being expandable from a first diameter at which the expandable supportive endoluminal graft is insertable into a body pathway to a second diameter, said second diameter being greater than said first diameter;a liner constructed of an essentially inert biocompatible material, said liner applied to said internal surfaces; anda cover constructed of an essentially inert biocompatible material, said cover applied to said external surface;wherein said liner is bonded to said cover at locations defined by said open areas of the tubular supporting component; andsaid liner and said cover are both made from a porous elastomeric material that provides a structure which allows normal cellular ingrowth, said porous elastomeric material selected from the group consisting of grafts constructed by electrostatic spinning of polymeric fibers, elution of particulate materials from polymeric sheeting, and solvent phase inversion from polymeric sheeting.
