Patent ID: 8527066

Claim:
A method for ensuring proper and safe attachment of a medical implantable lead to an organ inside a human or animal body for monitoring and/or controlling of the function of the organ by means of electrical signals, the medical implantable lead comprising an indication arrangement of a radiopaque material for visibility by means of fluoroscopy in an implanted state, the method comprising the steps of: providing a displaceable first indication marker of a radiopaque material being movably arranged in relation to a distal portion of the lead which in an initial position protrudes an initial distance in a longitudinal direction from the distal end of the lead and is displaceable in a longitudinal axial direction of the lead against the action of a resilient member which acts to displace the displaceable first indication marker towards the initial distance; providing a second indication marker, also of a radiopaque material, in relation to which the first indication marker is displaceable; implanting the medical implantable lead inside the human or animal body by attaching a fixation element to the organ, wherein the displaceable first indication marker translates in a proximal direction in response to the fixation element penetrating the organ; monitoring the attachment procedure by means of fluoroscopy; and comparing the relative positions of the first and second indication markers, which are indicative of whether the distal end of the medical implantable lead is in proper contact with the tissue or not.
