A medical dressing is described that includes: a porous layer having a first side and a second side; a first coating extending along at least a portion of the surface area of said first side of said porous layer; a second coating extending along said first side of said porous layer, said second coating comprising a pattern of through openings; wherein said first coating extends along at least those portions of the surface area of said first side of said porous layer that coincide with the through openings of said second coating and wherein said first surface of said second coating extends in a plane (B) that is farther away, in the vertical direction, from the first side of said porous layer, than the corresponding plane (A) defined by the first surface of said first coating.

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.
