Porous wound dressing for use in negative-pressure therapy
11291588 · 2022-04-05 · ·

A porous wound dressing for use in negative-pressure therapy is proposed. The wound dressing has an outer edge which defines a substantially oval or rectangular outer shape of the wound dressing with a major axis and a minor axis. The wound dressing has one or more incisions or perforations which together form one or more arc-shaped lines and serve for cutting the wound dressing to size in order to adapt the wound dressing to the shape and/or size of a wound. The one or more arc-shaped lines each extend asymmetrically with respect to the major axis and/or to the minor axis and each enclose, together with a portion of the outer edge, a segment of the wound dressing that is designed for separation from the wound dressing.

Melt Blown Dressing with Gradient Density

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.
