Title:
SHEET-LIKE DECELLULARIZED MATERIAL AND ARTIFICIAL BLOOD VESSEL EMPLOYING SAID MATERIAL
Document Type and Number:
WIPO Patent Application WO/2019/087880
Kind Code:
A1
Abstract:
The present invention relates to a sheet-like decellularized material of biological material origin, wherein the maximum value of the tensile strengths in four directions is equal to or greater than 4 MPa, and the expansion rate in the direction in which the tensile strength reaches the maximum is 50% to 300%. The present invention provides a sheet-like material that is capable of maintaining a superior pressure resistance when used as a blood vessel or when used to repair a blood vessel.
