The PERFORMER HT system, together with its accessories and consumables, make up an electromechanical system used to treat local hyperthermia by circulating hot fluids in the peritoneal or pleural cavity. It is particularly indicated in the following therapies: 1. Intraperitoneal or intrapleural perfusion in order to help localized hyperthermia through heated defluid circulation, which may contain chemotherapeutic drugs, in the peritoneal or pleural cavity. 2. Isolated perfusion of the organ consisting of isolating an anatomical area followed by an intra-arterial perfusion of chemotherapeutic drugs under hyperoxia / hypoxia conditions.
