Abstract
Dispositif modifiant au moins une partie d'un site donné de tissus contenant du collagène, au moins partiellement adjacent à un milieu liquide. Le dispositif comprend un système fournisseur d'énergie conçu pour délivrer une certaine énergie au site considéré. Le système en question comprend une partie distale équipée d'un capteur, lequel fournit à une unité de commande asservie un signal indiquant le degré d'énergie thermique du site choisi sur les tissus contenant du collagène et du milieu liquide adjacent. En recevant un tel signal, l'unité asservie règle le niveau de l'énergie transmise via le système fournisseur.
