If the game gets to that stage then there's not much else you can do.
So long as you get fast levels, fast aghs, good split farming, help out in ganks/team fights then you are doing your part.
Personally I like aghs -> travels, but some say vlads is needed first and for gank blink is better.
But in the situation where you just have to defend, meepo cannot be utilized, so perhaps you can say your team should have made more space for you. Or maybe you should have ganked earlier to help push advantage.
