Each umbrella shaped SMB Copper 250 (Cu 250) frame is made from compound of Low Density Polyethylene and Barium Sulphate (15% - 24%) with two flexible arms with spurs. A copper wire (diameter 0.30mm) is wound around the stem, giving a total copper surface area of 250mm2 ±10mm2. The frame is equipped with monofilament nylon (suture) for easy removal. It is packed with an insertion tube in a Tyvek - Mylar film pouch or Mylar- Mylar film pouch. The insertion tube is equipped with a movable flange to aid in gauging the depth to which the insertion tube should be inserted through the cervical canal and into the uterine cavity. Centimeter Scale printed in blue is provided on the Insertion Tube for exact positioning of the flange on the Insertion Tube before Insertion. The flexible side arms ensure that IUD remains in position as high as possible against the fundus , without the uterine cavity being stretched at all.
