Abstract

The artificial organ comprises a hydrodynamic rotation blood pump and a drive motor. Pref. the components of the pump coming directly into contact with the medium within the organ in which the pump is implanted are mfd. from water-repellant inert material i.e. PTFE or an interpolymer of perfluorpropylene and vinylidene fluoride or an interpolymer of trifluorchlorethylene and vinylidene fluoride.
