Medial umbilical ligament
The medial umbilical ligament (or cord of umbilical artery, or obliterated umbilical artery) is a paired structure found in human anatomy. It is on the deep surface of the anterior abdominal wall, and is covered by the medial umbilical folds (plicae umbilicales mediales). It should not be confused with the median umbilical ligament, a different structure that represents the remnant of the embryonic urachus.

Ligamentum umbilicale mediale
It represents the remnant of the fetal umbilical arteries, which serves no purpose in humans after birth, except for the initial part that becomes the adult superior vesical artery.
The medial umbilical ligament arises from the anterior division of the internal iliac artery.
It may be used as a landmark for surgeons exploring the medial inguinal fossa during laparoscopic inguinal hernia repair. Other than this, it has no purpose in an adult and it may be cut or damaged with impunity.
