Abstract
An adhesion-preventing material having a high adhesion-preventing effect has been demanded. An adhesion-preventing material including a sterilized biocompatible sponge-like laminate, wherein the sponge-like laminate comprises a sponge-like first layer and a sponge-like second layer each of which is at least partially crosslinked with a curing agent and comprises a low-endotoxin alginic acid monovalent metal salt, the alginic acid monovalent metal salt in the first layer has a weight average molecular weight of 10,000 to 2,000,000, the alginic acid monovalent metal salt in the second layer has a weight average molecular weight of 1,000 to 1,000,000, the weight average molecular weights are measured by a GPC-MALS method after a decrosslinking treatment, and the weight average molecular weight of the alginic acid monovalent metal salt in the first layer is higher than that in the second layer.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
