Methods of forming crosslinked hyaluronic acid anti-adhesion barriers, crosslinked hyaluronic acid anti-adhesions barriers, methods for preventing or inhibiting adhesions, and methods of promoting healing of a wound are provided. The method of forming the crosslinked hyaluronic acid anti-adhesion barrier includes freeze-drying a solution including hyaluronic acid to form a hyaluronic acid foam, which is then reacted with a crosslinking agent to form a crosslinked hyaluronic acid foam. The crosslinked hyaluronic acid foam is mixed with a solution containing hyaluronic acid to form an anti-adhesion barrier.
Cette invention concerne des procédés d'obtention de barrières anti-adhésion à base d'acide hyaluronique réticulé, les barrières anti-adhésion à base d'acide hyaluronique réticulé elles-mêmes, des procédés propres à empêcher ou à inhiber les adhésions et des procédés favorisant la cicatrisation de lésions. Pour l'obtention de barrières anti-adhésion à base d'acide hyaluronique réticulé, on congèle une solution renfermant de l'acide hyaluronique pour former une mousse d'acide hyaluronique, mousse qui, soumise à une réaction avec un agent réticulant, forme une mousse d'acide hyaluronique réticulé. Mélangée à une solution renfermant de l'acide hyaluronique, cette mousse d'acide hyaluronique réticulé forme une barrière anti-adhésion.
