Patent number: 12251451Abstract: The present description relates to an injectable emulsion comprising an amphiphilic compound, a first phase comprising droplets including at least one perfluorocarbon compound and a second phase, which is aqueous. The droplets have a diameter d4,3 of between 0.5 pm and 5.5 pm, and the at least one perfluorocarbon compound has a boiling point above 100° C. The present description also relates to methods comprising administering such an injectable emulsion in, for example, ultrasound ablation surgery (FIG. 3).Type: GrantFiled: June 14, 2019Date of Patent: March 18, 2025Assignees: Avignon Université, CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE—CNRS, INSTITUT NATIONAL DE LA SANTÉ ET DE LA RECHERCHE MÉDICALE, Sorbonne Université, UNIVERSITE DE MONTPELLIER, ECOLE NATIONALE SUPERIEURE DE CHIMIE DE MONTPELLIERInventors: Christiane Contino-Pepin, Stéphane Desgranges, Nicolas Taulier
