Title:
BIOLOGICAL TISSUE ADHESIVE SHEET, BIOLOGICAL TISSUE REINFORCING MATERIAL KIT, AND METHOD FOR MANUFACTURING BIOLOGICAL TISSUE ADHESIVE SHEET
Document Type and Number:
WIPO Patent Application WO/2021/054232
Kind Code:
A1
Abstract:
The present invention provides a biological tissue adhesive sheet having exceptional tissue adhesion. A biological tissue adhesive sheet according to an embodiment of the present invention includes a nonwoven fabric formed from fibers that include a crosslinked gelatin derivative, the gelatin derivative being represented by formula 1. Formula 1: Gltn-NH-L-CHR1R2 (In formula 1: Gltn represents a gelatin residue; L represents a single bond or a divalent linking group; and R1 and R2 each independently represent a C1-20 hydrocarbon group or a hydrogen atom, at least one selected from the group consisting of R1 and R2 being the hydrocarbon group.)
