Abstract
A biomimetic tissue scaffold for repairing an elongated tissue in need of repair can comprise a plurality of coiled flexible polymeric ribbons having a surface on which is formed an array of nanofibers, the ribbons forming a tubular body defining a first open end in which a first end of the elongated tissue is receivable, a second open end in which a second end of the elongated tissue is receivable, and a lumen extending between the first and second open ends.
Claims10
A tissue scaffold, comprising:
- a plurality of coiled flexible polymeric ribbons, each ribbon having a surface on which is formed an array of nanofibers;
- wherein:
- the ribbons are arranged as a plurality of layers of coiled flexible polymeric ribbons,
- each layer supports or is supported by an adjacent layer, and
- each layer has a handedness which differs from that of each adjacent layer.
2 more elements
A tissue scaffold, comprising:
- a first layer comprising a first plurality of coiled flexible polymeric ribbons, each ribbon having a surface on which is formed a first array of nanofibers;
- a second layer comprising a second plurality of coiled flexible polymeric ribbons, each ribbon having a surface on which is formed a second array of nanofibers;
- wherein:
- the first layer defines a first open end, a second open end, and a lumen extending between the first and second open ends, and
- the second layer overlaps the first layer.
2 more elements
A tissue scaffold, comprising:
- a plurality of flexible polymeric ribbons, each ribbon having a surface on which is formed a first array of nanofibers;
- wherein the flexible polymeric ribbons are interlaced to form a tubular body defining a first open end, a second open end, and a lumen extending between the first and second open ends.
