Is Narutos mom the seal?

Naruto's dad used part of his chakra and his wife's (naruto's mom) chakra to seal the Nine-tailed fox inside Naruto. They aren't the seal but they are there to help Naruto control the demon fox. Naruto's dad saves naruto from being overwhelmed by the fox, and in the most recent manga (495 or thereabouts) his mom helps him defeat the fox.
