Hernia repair graft with anti-adhesive material layers
The patent US12070380B2 describes a novel hernia repair graft that consists of a two-layer structure designed to enhance surgical outcomes. The first layer features a mesh material, which can be made from various non-absorbable substances such as polypropylene, polytetrafluoroethylene (PTFE), nylon, or polyester, and incorporates an embroidered pattern. The second layer is composed of an anti-adhesive material, specifically a medical textile or biotextile, which may include extracellular matrix (ECM) derived from biological tissues. The two layers are flexibly connected through discrete attachment sites, allowing for relative movement between adjacent regions, which may help reduce complications associated with tissue adhesion.
Further claims detail specific characteristics of the mesh, including its pore size, filament diameter, and stitching patterns. The mesh can be warp knitted and may feature a first pattern of stitching that interlocks at regular intervals or overlaps with a second stitching sub-pattern. The attachment sites can also be arranged in a grid pattern, with a specified density that is less than 10 attachments per square millimeter. This innovative design aims to improve the functionality and biocompatibility of hernia repair grafts, potentially leading to better patient outcomes in surgical applications.
