I found this else-where and thought you might appreciate someone elses input.
"Hi Girls,
Just thought I'd post this, as seen a few posts asking about induction, as this is what they used at my hospital to induce me when I was Pregnant with my DD and wanted to go for a VBAC - had to be induced early due to medical complications.
Cervical dilator catheter (Foley Catheter)
A foley catheter is used by some health care professionals to help the cervix dilate. A thin, plastic catheter with a small balloon on one end is inserted into your cervix. Water is slowly pushed through the catheter, allowing the balloon to inflate. As the balloon inflates, pressure is exerted against your cervix, causing your body to release prostaglandins. These hormones then cause your cervix to dilate. Once your cervix has dilated enough, the balloon falls out and the catheter can be removed.
This is a fairly new technique used to dilate the cervix, and is associated with better and safer results.
May be something for those worried about induction to ask their consultants about - I had the balloons in for 24 hours after which they were removed and I was 4cm from zero - I was taken to labour ward for my waters to be broken and my DD arrived 3 hours later - no drugs needed!!!
Hope this info helps, take care and best wishes"
