Use of collagen in the manufacture of a membrane. The invention concerns the use of collagen gel in the manufacture of an optionally crosslinked, transparent, biocompatible collagen membrane which can be sutured or stapled and is, preferably, rapidly resorbed, for use in surgery under peritoneoscopy, such as parietal surgery. The membrane is produced by drying the collagen gel in a non-toxic gaseous fluid such as air or nitrogen. The membrane enables the peritoneum to rapidly renew itself, thereby preventing post-operative adhesions. The surgeon inserts the membrane using a trocar with a diameter of 1 cm and it can be safely secured by stapling or suturing with the vessels being visible beneath it. |
