MIDCAL

The MIDCAL ™ is a non-adjustable gastric ring designed for gastric bypass calibration. It is made of medical-grade silicone, for long-term implantation. It is visible by X-ray by means of these radiopaque strips, and has three locking positions to adjust to the size of the gastric pouch (circumference of 65, 70, 75 and 80 mm).
