inserting a catheter with an inflatable balloon and supporting a removable barrier structure at a distal end portion thereof to a position proximate a patient's cervix, wherein the removable barrier structure comprises a first aperture with a flexible band disposed therethrough;
aligning the removable barrier structure such that the flexible band is in registry with the patient's cervix;
inflating the inflatable balloon to compress the cervical tissue;
wrapping the flexible band around the cervical tissue and tying opposite ends of the flexible band to maintain the cervical tissue in a closed configuration;
deflating the inflatable balloon, disconnecting the removable barrier structure from the distal end portion of the catheter, and removing the catheter from the patient;
performing one or more vaginal cerclage stitches upon the cervical tissue;
cutting the flexible band and removing the flexible band and removable barrier structure from the patient.
