The invention relates to a biocompatible, bioresorbable and non-toxic adhesive composition for surgical use, for the bonding, in particular, of biological tissues to one another or in an implanted biomaterial, characterized in that it comprises a reactive acidic solution of non-crosslinked and potentially crosslinkable collagen or gelatin modified by oxidative cleavage, at a concentration which is preferably between approximately 5 and 30 by weight. It also relates to reactive acidic solutions and powders based on non-crosslinked collagen or gelatin modified by oxidative cleavage which are used as intermediate products in the preparation of the above-mentioned composition, and to the process for their preparation. It also relates to adhesive kits which comprise, on the one hand, the above-mentioned reactive acidic solution and, on the other hand, a neutralizing solution and which are intended for extemporaneous mixing. Finally it relates to a method of application of the adhesive, composition according to the invention. The invention is particularly useful in the areas of adhesion, haemostasis, leaktightness with respect to liquids or gases, cicatrization, filling, avoiding adhesion in surgery, embolization, as a local system for release of medicamentary active principles, etc.
Non-crosslinked and potentially crosslinkable pepsin-treated collagen or gelatin powder modified by oxidative cleavage in an aqueous solution, which is soluble at an acidic pH and stable on storage at a temperature of below 0.degree. C. and for a period of at least one month.
Concentrated reactive acidic solution of non-crosslinked and potentially crosslinkable pepsin-treated collagen or gelatin modified by oxidative cleavage, substantially free from iodine or iodine derivatives and which is stable for a period of time of at least one month on storage at a temperature of below 0.degree. C., to form an adhesive composition.
Biocompatible, bioresorbable and non-toxic adhesive kit intended for surgical use for the bonding, in particular, of biological tissues to one another or to an implanted biomaterial, characterized in that it consists of:
