Abstract: A perforated unitary multi-laminar tissue graft construct and method for preparing such construct is described. The method comprises overlapping strips of submucosa tissue with other strips of submucosal tissue, compressing at least the overlapped portions of said strips between two surfaces under conditions that allow or promote dehydration of the compressed submucosa sheets, and perforating the resulting unitary tissue graft construct. The perforated tissue graft compositions have enhanced mechanical and remodeling properties relative to non-perforated submucosal tissue grafts.

Abstract: Multi-laminar tissue graft constructs, pseudoisotropic graft constructs and a method of preparing such constructs are described. Multi-laminar tissue graft constructs are prepared by fusing partially overlapped strips of submucosa tissue into a unitary graft construct by compressing the tissue under dehydrating conditions. Pseudoisotropic tissue graft constructs are prepared by overlapping a first strip of submucosa tissue with at least two strips of submucosa tissue orientated so that the longitudinal axis of each strip formts an angle of about 180.degree./N with the longitudinal axes of at least two other strips of submucosal tissue.

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.
