Abstract

A collagenous dressing which is characterized in that it contains collagen in combination with a resorbable biopolymer from the group comprising fibrinogen, gelatin modified by SH groups, collagen modified by SH groups, or regenerated oxycellulose modified by SH groups. Said collagenous dressing is tissue-agglutinable and does not have the disadvantages of conventional fibrin bonding in combination with resorbable collagen.
