Disclosed are a medical material and a production process thereof. The medical material has a membrane configuration and is produced by impregnating a membranous material with collagen or gelatin and then physically or chemically cross-linking protein molecules of the membranous material. The membranous material is essentially acellular compact layer of a biogenic connective tissue. The medical material may further be processed into other forms such as threads, braids, tubes and hoses and is useful in surgery. The medical material has a strength sufficient to be useful for surgically stitching wounds either manually or mechanically.

A method for manufacturing a medical material having a membrane configuration, a thread or string configuration or a tube or hose configuration, which comprises, providing a membranous material which consists essentially of a compact layer that is only an acellular layer of a biogenic connective tissue; impregnating the membranous material with collagen or gelatin; forming physical or chemical cross-linkings between protein molecules of the compact layer to such an extent that the resulting material has sufficient physical strength to be useful for manual or mechanical suture in surgery; where required, forming a thread or string from the resulting material; and where further required, forming a tube or hose from the thread or string.
