Abstract
The application describes devices, systems and methods related to an implantable device that is a stent or a heart valve. The implantable device includes a pressure sensor. The implantable device is for being introduced into a subject and for being wirelessly read out by an outside reading system. The pressure sensor comprises a casing with a diffusion blocking layer for maintaining a predetermined pressure within the casing and a magneto-mechanical oscillator with a magnetic object providing a permanent magnetic moment. The magneto-mechanical oscillator transduces an external magnetic or electromagnetic excitation field into a mechanical oscillation of the magnetic object, wherein at least a part of the casing is flexible for allowing to transduce external pressure changes into changes of the mechanical oscillation of the magnetic object.
