The implantable medical device for measuring pressure is disclosed. The implantable medical device is connectable to a medical lead and comprises an outer sheath and a helically shaped needle arranged at the outer sheath. A pressure sensing body having a distal part is movably arranged in the outer sheath. The pressure sensing body is arranged such that the distal part is located within the outer sheath in an initial state of the pressure sensing body, wherein the pressure sensing body is arranged to be advanced from the initial state to protrude from the outer sheath and such that it is at least partially surrounded by the helically shaped needle； and a pressure sensor arranged at or adjacent to the distal part of the pressure sensing body for sensing pressure.
