Abstract
An elastic sheet for re-activating an endometrial basal layer in a uterine cavity comprises a silicone rubber and a drug, wherein the drug is encased inside the silicone rubber in the manner of a drug storage zone, or uniformly dispersed inside the silicone rubber, or carried by an outer surface of the silicone rubber as a coating, and the drug comprises an estrogen. A method for forming the elastic sheet with a drug in a matrix-type elastic sheet; or as a sustained release coating is provided. The estrogen is loaded on the silicone rubber, and thus the endometrial basal layer is continuously activated through drug stimulation, allowing for the endometrial basal layer to re-proliferate the functional layers, thereby restoring the normal endometrial structure and completely preventing adhesions.
