The midline catheter tube is shorter than a PICC line. The midline tube ends in a vein below your armpit. Having a PICC or midline catheter may allow you to receive long-term intravenous (IV) medicine or treatments. PICC lines and midlines can stay in place longer than some other types of IV catheters. PICCs and midlines are used for IV therapy given for more than five days at a time. Having a PICC or midline may decrease the number of needle sticks that you need to get medicine, or have blood samples collected.
