IMPLANTABLE DEVICE INCLUDING PRESSURE SENSOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 18237953 titled 'IMPLANTABLE DEVICE INCLUDING PRESSURE SENSOR
Simplified Explanation
The patent application describes an implantable device, such as a stent or heart valve, that includes a pressure sensor. The device can be wirelessly read out by an external reading system. The pressure sensor consists of a casing with a diffusion blocking layer and a magneto-mechanical oscillator with a magnetic object. The oscillator converts an external magnetic or electromagnetic field into a mechanical oscillation of the magnetic object. The flexible casing allows for the conversion of external pressure changes into changes in the mechanical oscillation of the magnetic object.

Original Abstract Submitted
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.
