An absorbable hemostatic nonwoven patch utilizes a biocompatible substrate comprised of melt-blown microfibers as webbed sheets that are layered and bonded/entangled in descending density and ascending porosity; 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.

The present invention relates to a multilayered wound dressing particularly for wound treatment in the granulation and epithelization phase. The wound dressing comprises a) a first layer as a wound contact layer having a first side and a second side, and b) at least one second layer as an absorbent layer having a first side and a second side and comprising a hydrophilic polyurethane foam, wherein the polyurethane foam comprises a water fraction of at least 10% by weight of water.

According to the invention, a wound dressing may be further developed, whereby a wound dressing made from a planar structure with a first main direction of extension and at least one further main direction of extension, whereby the textile planar structure, at least along the main directions of extension comprises extensibility properties which differ by less than 80%, preferably less than 50%.

The present invention is directed to an absorbable hemostatic patch that utilizes a biocompatible fibrous, fabric substrate that is melt-blown and napped or loosened at the surface, with the substrate having a low-profile, high flexibility, strength and porosity that is suitable for coating cross-linkable active molecules and ultimately effective for use as a hemostat in situations of problematic bleeding.

A dressing including a film which is impermeable to fluids and permeable to water vapor, and the entire surface of which is covered by a perforated reinforcement coated with a medically acceptable adhesive which is the same or different on each of the faces thereof, the face opposite to the face in contact with the impermeable film of an adhesive being partially covered by an absorbent pad, The dressing further includes a layer for distributing the fluids which is positioned between the impermeable film and the perforated reinforcement.

Embodiments disclosed herein are directed to the treatment of wounds using negative pressure. Some embodiments disclosed herein provide for a foam pad, which may be suitable for use in abdominal wound sites, and which may be sized in a dimensionally-independent manner. Additional embodiments provide for a wound contact layer, as well as a system for the treatment of abdominal wounds.

A bandage comprising a substrate having a first surface with a plurality of superhydrophobic particles attached to the first surface. The plurality of superhydrophobic particles can be porous diatomaceous earth particles having a hydrophobic layer conforming to the surfaces of the DE particles, where the hydrophobic layer is bound to the DE particles. The plurality of attached superhydrophobic particles can render the first surface superhydrophobic, while a second surface opposite the first surface can be hydrophilic or hydrophobic. The substrate can be breathable in order to maintain skin health for the tissue underlying the bandage. The substrate can be selected from porous films, apertured films, textiles, nonwoven materials, impregnated composites thereof, and combinations thereof.

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.
