How do I handle a long gap on my résumé? - what worked for you?

My résumé shows a gap from a layoff and some health issues. I am nervous about being filtered out. Did anyone get past it?

Thanks for writing this out. I went through something close to it last year, and it settled down once I kept a simple log of every call and form.

Keep everything in writing and save the confirmation numbers. It made the follow-up calls so much easier.
