The stent graft 1 is attached between the blood vessel wall 3 and the metal stent 2 after the metal stent 2 is expanded, and blood flows in the stent graft 1. When the metal stent 2 includes the conductive coil 21, that is, when the metal stent 2 and the conductive coil 21 exist independently, the coating 1 may also be coated on the outer sides of the metal stent 2 and the conductive coil 21.

In the embodiment of the present disclosure, the metal stent 2 may be sewn or adhered to the covering film 1.

Under the condition that the conductive coil 21 exists independently, the conductive coil 21 can be positioned between the piezoelectric film 4 and the metal support 2 or between the covering film 1 and the piezoelectric film 4 as long as the conductive coil 21 is ensured to be in contact with the piezoelectric film 4.
