The 25th Amendment outlines how to act when there is a vacancy in the office of the Vice President or the President, whatever the reason may be: resignation, disability, or death.
Section 3 talks about what the President should do if he or she becomes temporarily disabled to discharge the powers and duties of his or her office. In such case, he or she must submit a letter to the President pro tempore of the Congress notifying his or her condition. Then, the Vice President will assume his or her duties and powers temporarily until President submits another written declaration that he or she is no longer disabled.
