The B-Band is implanted around the stomach pouch in gastric bypass patients to stabilise the gastroenterostomy and reduce later dilation of the stoma, thereby promoting more sustained weight loss. The B-Band allows precise adjustment of the required diameter during implantation. The band circumference can be adjusted every 2 mm until the inner diameter of the implant matches the outer diameter of the encircled stomach tissue. Use of a gastric tube enables the size to be standardised. Markings on the band (at 6.5 cm, 7.5 cm, and 8.5 cm) allow exact documentation of the band size during implantation.
