    摘要: A composite implant is provided for repairing a tissue defect in a patient. In one embodiment, the implant is a porous tissue scaffold having at least one pocket formed therein and adapted to contain a viable tissue. The tissue scaffold can have a variety of configurations, and in one embodiment it includes top and bottom portions that can be at least partially mated to one another, and in an exemplary embodiment that are heated sealed to one another around a perimeter thereof to form an enclosed pocket therebetween. The pocket is preferably sealed with a viable tissue disposed therein. In another embodiment, the tissue scaffold is substantially wedge-shaped and the pocket comprises a hollow interior formed in the tissue scaffold, and/or at least one lumen extending into the tissue scaffold. The tissue scaffold can also optionally include at least one surface feature formed thereof to promote blood vessel formation.
