    摘要: Large-area medical graft devices comprise at least two sheets of extracellular matrix material (ECM). The sheets of ECM have overlapping regions that are compressed together during a non-drying process, and other overlapping regions that are not compressed together. The compressed overlapping regions have a more collapsed matrix structure, while the non-compressed overlapping regions having a more open matrix structure. The sheets of ECM can have a stacked orientation to create a desired thickness, or a staggered orientation to create a desired surface area, or combinations of both orientations.
