There are provided tissue repair laminates which promote cellular in-growth but also prevent or mitigate tissue adhesion. The laminates comprise a biodegradable polyurethane foam layer which facilitates cellular infiltration and a polyurethane barrier layer which is non-adhesive to tissue. The laminates resist shrinkage under in vivo conditions and possess desirable mechanical properties. The laminates find use in, for example, the repair of herniated tissue, particularly, but not limited to hernias in the abdominal wall.
