COMPOSITE FIBER
20210162090 · 2021-06-03 · ·

The present invention provides a composite fiber which comprises an alginate fiber, a polymer material, an antibacterial agent, and a plasmid encoding growth factor-gene. The present invention also provides a wound dressing, wherein the wound dressing comprises a composite fiber as described above. The composite fibers prepared according to the present invention are capable of releasing the antibacterial agent and the growth factor gene, not only to reduce microorganism growth, but also to secrete growth factors in a wound site through transfection, thereby promoting wound healing.

Wound dressing for use in vacuum therapy

A wound dressing for use in vacuum wound therapy comprising a wound contact layer which is an open structure comprising a yarn comprising gel-forming filaments or fibres, the structure having a porosity which allows exudate to flow through it.

Articles of poly(butylene succinate) and copolymers thereof

Resorbable implants, coverings and receptacles comprising poly(butylene succinate) and copolymers thereof have been developed. The implants are preferably sterilized, and contain less than 20 endotoxin units per device as determined by the limulus amebocyte lysate (LAL) assay, and are particularly suitable for use in procedures where prolonged strength retention is necessary, and can include one or more bioactive agents. The implants may be made from fibers and meshes of poly(butylene succinate) and copolymers thereof, or by 3d printing molding, pultrusion or other melt or solvent processing method. The implants, or the fibers preset therein, may be oriented. These coverings and receptacles may be used to hold, or partially/fully cover, devices such as pacemakers and neurostimulators. The coverings, receptacles and implants described herein, may be made from meshes, webs, lattices, non-wovens, films, fibers, foams, molded, pultruded, machined and 3D printed forms.

Textile fabric for placing on the skin and/or a wound of a patient, and transdermal patch and arrangement consisting of a transdermal patch and an evaluation unit

A textile fabric is used to make a textile moisture sensor. The textile fabric has a top side facing away from the skin and/or a wound, and an underside that faces the skin and/or the wound and on which the textile fabric has a moisture-impermeable barrier. The textile fabric is formed from non-conductive warp threads, non-conductive weft threads, and conductive warp threads and/or conductive weft threads that are arranged such that an electrically conductive structure is formed in the textile fabric. The moisture-impermeable barrier on the underside of the textile fabric has at least one opening and conductive warp and/or conductive weft threads arranged in the region of the opening such that the conductive threads can come into contact with moisture from the skin and/or wound in the region of the opening.

Graded Porous Scaffolds as Immunomodulatory Wound Patches
20210046213 · 2021-02-18 ·

The present invention provides porous biomimetic scaffolds and methods for making the same. The scaffolds have graded pore sizes for enhanced cell penetration. The scaffolds are useful for wound regeneration by facilitating cell penetration into the scaffold interior and due to their inherent immunomodulatory effects. The scaffolds have tissue modeling specification by mimicking the inherent stratified structure of certain tissues.
