I haven't tried it, nor do I know anyone who does, but the principle upon which it's based (plug the Fallopian tube with something that will force the tube to scar over, permanently blocking the tube) is pretty sound. I'd guess that you would have this implanted in your doctor's office, but they'd have to dilate your cervix for it, so it could be a little on the painful side. But, no anesthesia, no incisions, so the recovery time should be really short. It will take a little while for the scars to form, so you'd need a backup method of BC in the meantime.
I see that the website of the company making the
Essure device has a lot of reasonable information posted, but I do not have any anecdotal evidence to share. From the point of view of a biologist, though, I think it appears to be kosher. You'll probably want to talk with your doc about it, though.
You might want to cross-post your question to the "All things Uterine" thread and see if any of the regulars there can answer it.
