Title:
DEVICE FOR MUCOUS MEMBRANE REGENERATION AND METHOD FOR TREATING MUCOUS MEMBRANE DEFECT USING SAME
Document Type and Number:
WIPO Patent Application WO/2017/110776
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a means whereby epithelialization (re-covering) of a mucous membrane defect portion following ESD surgery can be promoted inexpensively and with a simple method, while preventing esophageal stenosis. Provided is a device for mucous membrane regeneration that is characterized in being a folded part which is formed from a collagen bitolyl gel sheet obtained by connecting a plurality of vertically long collagen bitolyl gel thin film pieces , and in which one side orthogonal to the connected connecting lines is folded in half.
