James, my DH also has the MicKey(also known as the button). He had to have it replaced about a month ago, this after about 9 months. It was completely deflated and could have pulled right out. He has not had any bleeding or leakage, but some discomfort which we think is due to the "bubble" being inflated again to keep it anchored and taking up a bit more space in the stomach than the deflated one that he was used to for who knows how long because the solution was gone. Let us know what your GI doc has to say.
