A device for forming a stoma opening in the stomach or esophagus of a patient comprises an elongated restriction member (2), forming means (10) for forming the elongated restriction member into at least a substantially closed loop around the stomach or esophagus, said loop defining a restriction opening (3), and an adjustment means (12) for adjusting the restriction member in said loop to change the size of said restriction opening. The adjustment means (12) is designed to mechanically adjust the restriction member in a non-invasive manner to allow post-operation non-invasive adjustments of the restriction member. <IMAGE> |
