Biomedical patches with aligned fibers

A fiber structure for repairing a void in a biological tissue, the fiber structure comprising an a set of one or more inner point(s), a set of one or more inner area(s) extending from the one or more inner point(s) to a set of one or more inner perimeter(s), and a set of one or more outer area(s) extending from the one or more inner perimeter(s) to a set of one or more outer perimeter(s), wherein the one or more inner area(s) and the one or more outer area(s) at least partially overlap, the fiber structure comprising a first set of one or more substantially straight polymeric fiber sections extending from the inner point(s) to the inner perimeter(s), and a second set of one or more substantially straight polymeric fiber sections extending from the inner perimeter(s) to the outer perimeter(s),

• wherein a spatial fiber density of the one or more inner area(s) is substantially the same as a spatial fiber density of the one or more outer area(s),
• wherein each of the first set of one or more of substantially straight polymeric fiber sections and the second set of one or more of substantially straight polymeric fiber sections comprise one or more fiber sections generated by depositing via electrospinning a first polymer composition and one or more fiber sections generated by depositing via electrospinning a second polymer composition.

A fiber structure for repairing a wound in a biological tissue, the fiber structure comprising a non-peripheral point, an inner area extending between the non-peripheral point and an inner perimeter, and an outer area extending between the inner perimeter and an outer perimeter, wherein the inner area and the outer area at least partially overlap, the fiber structure comprising a first set of one or more of substantially straight polymeric fiber segments extending between the non-peripheral point and the inner perimeter, and a second set of one or more of substantially straight polymeric fiber segments extending between the inner perimeter and the outer perimeter,

• wherein the fiber structure comprises a substantially consistent spatial fiber density,
• wherein each of the first set of one or more of substantially straight polymeric fiber segments and the second set of one or more of substantially straight polymeric fiber segments comprises a first set of fiber segments comprising a first polymer composition and a second set of fiber segments comprising a second polymer composition.
