Abstract
Official abstract text for this publication.
The present invention provides a hemostatic porous composite sponge comprising:i) a matrix of a biomaterial; andii) one hydrophilic polymeric component comprising reactive groupswherein i) and ii) are associated with each other so that the reactivity of the polymeric component is retained, wherein associated means thatsaid polymeric component is coated onto a surface of said matrix of a biomaterial, orsaid matrix is impregnated with said polymeric material, orboth.
First claim
Opening claim text (preview).
What is claimed is: 1 : A method of manufacturing a hemostatic composite, comprising: contacting a sponge comprising a matrix of a biomaterial in dried form with a reactive polymeric material in the form of a solution so that the biomaterial is impregnated with the reactive polymeric material or the reactive polymeric material is coated onto a surface of the matrix of the biomaterial, or both; and drying the contacted biomaterial and reactive polymeric material. 2 : A hemostatic composite comprising a sponge comprising a matrix of a biomaterial that is impregnated with a reactive polymeric material obtained by the method of claim 1 . 3 : A hemostatic composite comprising a sponge comprising a matrix of a biomaterial that is coated with a reactive polymeric material obtained by the method of claim 1 . 4 : The method of claim 1 , wherein the reactive polymeric material is a reactive hydrophilic polymeric material. 5 : The method of claim 1 , wherein the reactive polymeric material is a single reactive hydrophilic polymeric material. 6 : The method of claim 1 , wherein the reactive polymeric material is a single hydrophilic polymeric material comprising electrophilic reactive groups, wherein the hydrophilic polymeric material is a hydrophilic crosslinker. 7 : The method of claim 1 , wherein the reactive polymeric material comprises a polyethylene glycol (PEG). 8 : The method of claim 1 , wherein the reactive polymeric material comprises a polyethylene glycol (PEG) comprising two or more reactive groups selected from the group consisting of succinimidyl esters (—CON(COCH 2 ) 2 ), aldehydes (—CHO), and isocyanates (—N═C═O). 9 : The method of claim 1 , wherein the biomaterial is impregnated with the reactive polymeric material. 10 : The method of claim 1 , wherein the reactive polymeric material is coated onto a surface of the matrix of the biomaterial.
