The present invention is directed to a reinforced absorbable multilayered hemostatic wound dressing comprising a first absorbable nonwoven fabric, a second absorbable woven or knitted fabric, thrombin and/or fibrinogen.

Reinforced absorbable multilayered hemostatis wound dressing

Method of making a reinforced absorbable multilayered hemostatic wound dressing

The present invention includes sterilized hemostatic compositions that contain a continuous, biocompatible liquid phase having a solid phase of particles of a biocompatible polymer suitable for use in hemostasis and that is substantially insoluble in the liquid phase, and sterile thrombin, each of which is substantially homogenously dispersed throughout the continuous liquid phase, and methods for making such compositions.

Hemostatic compositions containing sterile thrombin

The present invention includes both sterilized and unsterilized hemostatic compositions that contain a continuous, biocompatible liquid phase having a solid phase of particles of a biocompatible polymer suitable for use in hemostasis and which is substantially insoluble in the liquid phase, and a discontinuous, biocompatible gaseous phase, each of which is substantially homogenously dispersed throughout the continuous liquid phase, methods for making such compositions, medical devices that contain sterilized hemostatic compositions disposed therein and methods of making such devices.

Process of making flowable hemostatic compositions and devices containing such compositions

The present invention is directed to processes of making flowable hemostatic compositions and devices that include the flowable hemostatic composition disposed therein, where a volume of a biocompatible liquid, a volume of a biocompatible gas, and an amount of solid particles of a biocompatible polymer are mixed together to form a substantially homogenous composition including a discontinuous gas phase and the solid particles substantially homogenously dispersed throughout a continuous liquid phase to form a flowable hemostatic composition, and the composition then transferred into a device suitable for applying the flowable hemostatic composition to a site of a body requiring hemostasis under conditions effective to maintain the substantially homogeneous dispersion of the gas phase and the solid particles throughout the liquid phase.

The present invention is directed to a method of using a multilayered fabric comprising a first absorbable nonwoven fabric and a second absorbable woven or knitted fabric in tissue repair and regeneration.

Reinforced absorbable multilayered fabric for use in tissue repair and regeneration

The present invention is directed to a multilayered fabric comprising a first absorbable nonwoven fabric and a second absorbable woven or knitted fabric.

Reinforced absorbable multilayered fabric for use in medical devices

The present invention is directed to a hemostatic wound dressing that utilizes a fibrous, fabric substrate made from carboxylic-oxidized cellulose and containing a first surface and a second surface opposing the first surface, the fabric having flexibility, strength and porosity effective for use as a hemostat; and further having a porous, polymeric matrix substantially homogeneously distributed on the first and second surfaces and through the fabric, the porous, polymeric matrix being made of a biocompatible, water-soluble or water-swellable cellulose polymer, wherein prior to distribution of the polymeric matrix on and through the fabric, the fabric contains about 3 percent by weight or more of water-soluble oligosaccharides.

Hemostatic wound dressings and methods of making same

The present invention is directed to hemostatic devices comprising a substrate, which substrate comprises a precipitate of a protein in an amount effective to provide hemostatic properties to the substrate, or to maintain and/or improve hemostatic properties of the substrate, and to methods of making such devices, wherein the substrate comprising the precipitate of the protein is prepared by precipitation of the protein on or into the substrate upon contacting the protein with the substrate.

Hemostatic device containing a protein precipitate

The present invention includes both sterilized and unsterilized hemostatic compositions that contain a biocompatible liquid having particles of a biocompatible polymer suitable for use in hemostasis and which is substantially insoluble in the liquid, up to about 20 percent by weight of glycerol and about 1 percent by weight of benzalkonium chloride, each based on the weight of the liquid, all of which are substantially homogenously dispersed throughout the liquid to form a substantially homogenous composition, methods for making such compositions, medical devices that contain such hemostatic compositions disposed therein and methods of making such devices.

Hemostatic compositions and devices

Iodinated and/or brominated derivatives of aromatic dihydroxy monomers are prepared and polymerized to form radio-opaque polymers. The monomers may also be copolymerized with other dihydroxy monomers. The iodinated and brominated aromatic dihydroxy monomers can be employed as radio-opacifying, biocompatible non-toxic additives for other polymeric biomaterials. Radio-opaque medical implants and drug delivery devices for implantation prepared from the polymers of the present invention are also disclosed.

Radio-opaque polymer biomaterials

The present invention is directed to methods of making wound dressings that include the steps of contacting a fabric substrate having properties effective for use as a hemostat and containing fibers prepared from a biocompatible polymer, with a solution of a water-soluble or water-swellable biocompatible polymer under conditions effective to distribute the polymer solution substantially homogenously on and through the fabric substrate, transferring the fabric substrate to a lyophilization unit under conditions effective to maintain the homogeneous distribution on and throughout the substrate, and lyophilizing the fabric having the polymer solution distributed on and there through.
