Compliant biological scaffold
View Patent ↗A compliant scaffold incorporates a plurality of elongated apertures that form a geometric pattern enabling biaxial expansion or contraction. An elongated aperture has a pair of nodes located on opposing sides of the aperture and between a pair of antinodes located on the extended and opposing ends of the elongated aperture. A geometric pattern may have various geometric shapes, or tiles, between the plurality of apertures. The geometric tiles have a bounded perimeter formed by the plurality of elongated apertures. A substantial portion of the elongated apertures may be configured with the antinodes proximal to one of said pair of nodes of a separate elongated aperture; wherein the antinodes are closer to one of the pair of nodes than to any other antinode. This unique arrangement of the elongated apertures may be formed in biological material in vivo or ex vivo.

b) a plurality of geometric shapes having a bounded perimeter formed by said plurality of elongated apertures;
wherein upon biaxially expanding the compliant scaffold, the first and second nodes separate from each other and wherein a distance between the antinodes contracts to form an arrangement of tessellated apertures in the compliant scaffold;
wherein the plurality of elongated apertures forms said geometric pattern with a portion of elongated apertures configured with the antinodes proximal to one of said pair of nodes of a separate elongated aperture; wherein the antinodes are closer to said one of said pair of nodes than to any other antinode;
