Abstract
A tissue scaffold includes a first film having a plurality of cell openings and a second film adjacent the first film and having a plurality of cell openings larger than the cell openings of the first film. The cell openings of the first film interconnect with the cell openings of the second film to define pathways extending through the first and second films.
Claims28
A tissue scaffold comprising:
- a first film comprising a plurality of cell openings;
- and
- a second film adjacent the first film and comprising a plurality of cell openings offset in a predetermined arrangement from the cell openings of the first film;
- wherein the cell openings of the first film interconnect with the cell openings of the second film to define pathways with interconnecting pores of controlled area extending from the first film to the second film;
- wherein the diameter of a majority of the pores is less than the diameter of the cell openings of the first and second films that define each pore;
- and
- wherein at least one of the cell openings comprises a therapeutic agent selected from the group consisting of a growth factor, a biological cell, an antibiotic, an antiviral agent, an antifungal agent, a vitamin, and a mineral.
