Abstract
A peripherally inserted central venous catheter having a position indicator is used in a method of detecting movement of a catheter tip within a patient's superior vena cava. The PICC comprises a catheter having a proximal end with distance marks at measured intervals, an anchor wing system secured to the catheter's proximal end, at least one extension leg secured to the anchor wing system and the position indicator attached to the extension leg. The position indicator has an area for marking a distance signifying an initial external length of catheter which extends from the point the catheter enters the patient to the point it is attached to the anchor wing and/or marking an initial full length or the internal length of catheter which is fully within the patient. Any movement of the catheter's tip is detected by comparing the current external distance mark with the initial external distance mark.
