Since Jesus is Mary's savior, what did he save her from?

If Mary was born without original sin and remained sinless, even so Jesus was her savior, for she said, > “My soul glorifies the Lord and my spirit rejoices in God my > Savior..." (Luke 1:46-47) What do Catholics claim that Mary needed to be saved from? I imagine natural disasters, murderers, and Satan might be in the list, plus the grief of seeing her son executed. What does the church teach?
