Last I heard is that you calf is part of your leg or is there another Femoral Artery.
http://en.wikipedia.org/wiki/Femoral_artery
The following was copied directly from the link you provided (emphasis added):
The femoral artery is a general term comprising a few large arteries in the thigh. They begin at the inguinal ligament (femoral head) and end just above the knee at adductor canal or Hunter's canal traversing the extent of the femur bone.
You must have heard and read wrong. One's leg does not = one's femur.
