1. A method of making an implantable scaffold for repairing or regenerating body tissue, the method comprising the steps of:

  • cutting a naturally occurring extracellular matrix in the presence of a liquid to produce a cohesive mass of intertwined strips, ribbons, or fibers;

    contacting a synthetic polymer with the cohesive mass to make a composition comprising the cohesive mass and the polymer;

    freezing the composition comprising the cohesive mass and the polymer to form a frozen composition, said frozen composition comprising crystals, anddriving off the crystals to form a foam.
