<p>A synthetic material is disclosed, which is constituted by a copolymer of D, L-lactide and ε-caprolactone (which itself is characterised by lower degradation times than those obtainable with copolymers of L-lactic acid and ε-caprolactone), obtained by using as reaction control agent a sugar dianhydride with non-toxic characteristics. The use of sugar dianhydride in the reaction has a considerable control effect on the molecular weight of the copolymer and, thanks to its low molecular weight, this copolymer is characterised by extremely short resorption times, in the order for example of one or two months. The copolymer is used as covering element to be placed around tendon sutures and/or nerve tracts with the aim of preventing formation of scarry adherences between the suture lines and the soft surrounding tissues.</p> |
