摘要： A method for producing a biological cover includes providing a first material having a main body in a cylindrical configuration with at least one fold in the first material. A second material is arranged within the at least one fold. The first material is a biological material. The first material with the arranged second material is pressed onto a counter member arranged outside the cylindrical configuration. A crosslinking agent is applied to the first material. A biological cover is formed of a biological material having a main body in a cylindrical configuration having a first cylinder diameter. There is at least one fold in the main body. The at least one fold is configured to at least partially unfold upon radial dilation of the biological material to permit enlargement of the cylindrical configuration to a second cylinder diameter.
