Abstract
Methods to produce perforated collagen coated meshes for use as implants have been developed. The method involves positioning needles through the pores of the mesh, coating the mesh with a collagen solution, freezing the coated mesh, removing the needles from the frozen coated mesh, drying the collagen coated mesh, and optionally cross-linking the coated mesh. The method allows perforated collagen coated meshes to be prepared with variable thickness, and without damage to the surface of the mesh. The perforations of the collagen coated meshes may be designed to prevent the formation of fluid pockets when the coated meshes are implanted, and to permit rapid incorporation into host tissue. The perforated collagen coated meshes may be used for soft tissue repair, regeneration or remodeling including, for example, hernia repair, mastopexy, treatment of urinary incontinence, pelvic floor reconstruction, and ligament and tendon repair.
