Hernia-repair graft materials having anti-adhesion barriers

摘要

Graft materials for soft-tissue, especially hernia, repair that include an anti-adhesion barrier are disclosed by surgical reconstruction company Tela Bio of Malvern, Pennsylvania, USA. The anti-adhesion barrier inhibits the formation of post-surgical adhesions while matching the biomechanical properties of the tissue during healing and recovery, the company states. Featured in US Patent 10 561 485, the grafts can include a first layer comprising a substrate, such as a bioabsorbable or non-bioabsorbable mesh, and a second layer comprising a sheet of anti-adhesive material, such as extracellular matrix (ECM) derived from the dermis, pericardium, peritoneum, intestine, stomach or fore-stomach of ruminants.
