Abstract
A unitary heterolaminar tissue graft construct is prepared by fusing partially overlapped strips or sheets of submucosa tissue. The submucosa components are fused by compressing at least the overlapped positions of said strips between two surfaces under conditions that allow or promote dehydration of the compressed submucosa sheets. Three dimensional graft constructs can be prepared by using complementary non-planar compressive surfaces.
