Instrumented retrievable implantable device ( 2 ), comprising an expandable section, for placement inside a body lumen, preferably in a blood vessel. The device ( 2 ) comprises a joined sensor ( 70 ) for monitoring one or more physiological parameter for diagnostic or therapeutic purposes. Data access is assured by a passive RF transponder, in communication with an external readout unit or an implanted device, providing as well to the energy supply of the sensor ( 70 ). The shape of the device of the invention ( 2 ) allows repositioning and retrieval by micro-invasive methods, by means of a link section ( 20 ) capable of being coupled with a grabbing device ( 45 ) mounted on a catheter ( 40 ).
