How do Roman Catholics interpret Luke 4:13, regarding the devil leaving Jesus "until an opportune time"? Luke 4:13 (NIV) reads: 


  When the devil had finished all this tempting, he left him [Jesus] until an opportune time.


What is the Catholic interpretation of the phrase "until an opportune time"?  We do not find explicit reference to Jesus getting tempted by the devil after the temptations in the wilderness.  Is it that the devil was looking for opportunities, but did not find any? Or, is it that Jesus was frequently tempted to desert His mission all throughout His public life and on the cross? What are the Catholic teachings on such possibilities?
The last paragraph of the note to Lk 4:1-13 in the Navarre Bible New Testament Compact Edition has:


  [...]
  Jesus defeats the devil here, as he will also do at "an opprtune
  time" (v.13), that is, in his passion and death (cf. the note on
  22:1-6): his filial acceptance of the father's plans will liberate men
  from the one who has the power of death, that is, the devil (cf. Heb
  2:14). Jesus' victory over the tempter serves to encourage his
  disciples: if they trust in God, they will be able to defeat all
  temptation.
