MidCal Gastric Calibration Ring

MidCal – Gastric Calibration Ring for Banded Bypass

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 radio-opaque strips and has three locking positions to adjust to the size of the gastric pouch (circumference of 65, 70, 75 and 80 mm).


Why is Weight Regained after Gastric Bypass?

      • Gastric bypass is one of the most frequently performed operations in the world. It is known for its efficacy in terms of weight loss. However, after some years, the remaining stomach pouch can expand. This expansion, which increases the stomach volume, limits the effect of satiety. The quantity of food absorbed increases and usually leads to weight regain.
      • To avoid this expansion, a calibration ring such as the MidCal may be placed around the stomach. The stomach pouch remaining after gastric bypass is thus calibrated by the ring, and the risks of expansion are greatly reduced. Protecting the gastric reservoir in this way makes it possible to maintain the effect of satiety, and to limit the absorption of an excessive amount of food.
