(b)(4).The event is currently under investigation.

Event Description

It was reported on (b)(6) 2016 a physician performed an open myomectomy using an intrauterine balloon stent.The device was reported to have been tested by inflating and deflating the balloon prior to insertion and the doctor experienced difficulty deflating the balloon, having to use more force and twisting with the syringe to open the valve and release the fluid.On (b)(6), 24 hours after inserting the device, the physicians made the first unsuccessful attempt to remove the device using the syringe.The doctor attempted to deflate the balloon for approximately 30 minutes using excessive force, twisting, cutting the valve off and trying a different syringe.Support was called and the hospital staff was advised by the manufacturer to use ultrasound to determine the balloon volume and apply lubrication.Three hours later the attending physician's partner called support and reported the balloon was apparently fully inflated and she could see the balloon when trying to manipulate it.At this time the partner suggested puncturing the balloon with a needle.The physician administered a pudendal block and cervical block on the patient for pain and using a pudendal needle was able to puncture the balloon and deflate it so it could be removed, which reportedly took approximately one hour.The total time elapsed between first attempt and removal of the balloon was reported to be approximately 3.5 hours.The patient was seen for follow up on (b)(6) and allegedly experienced anxiety and needed extra pain medication, additionally more than normal bruising in the area around the vulva and labia was noted.A section of the device did not remain inside the patient's body.The patient did not require any additional procedures due to this occurrence.
