Zusammenfassung:The present invention is directed to an absorbable hemostatic nonwoven patch that utilizes a biocompatible substrate comprised of melt-blown microfibers as webbed sheets that are layered and bonded/entangled in descending density and ascending porosity; with the substrate having a high flexibility, strength and porosity that is suitable for coating cross-linkable active molecules and ability for laparoscopic use or trocar deployment, ultimately for functional use as a highly effective hemostat in addressing problematic bleeding during both open and minimally invasive surgical procedures.
