VERTICALLY ORIENTED BAND FOR STOMACH

摘要

An adjustable band or clamp or non-adjustable clamp is placed about the greater curvature of the stomach in a vertical orientation. The band or clamp completely compartmentalizes the stomach between a small vertical pouch and the fundus and body of the stomach. The fundus and body of the stomach are excluded from nutrients and are separated from a long narrow channel where the food travels. A small passage at the level of the antrum allows gastric juices to empty from the fundus and body of the stomach. The clamp may be applied during open surgery in laproscopic surgery or using a single port technique, or through any natural orifice in NOTES (Natural Orifice Transluminal Endoscopic surgery) or using a hybrid surgical technique.

主权项

1. A gastric band configured to partition a stomach into a first portion and a second portion, and to provide a passage between the first and second portions of the stomach, the gastric band comprising:
a partitioning section comprising a distal end of the gastric band and configured to extend from a first end of the stomach towards a second end of the stomach opposite the first end, the partitioning section having a first arm extending a majority of a length of the gastric band and a second arm extending a majority of the length of the gastric band and spaced apart from the first arm by a first distance configured to partition the stomach into the first and second portions; and a passage-forming section comprising a proximal end of the gastric band, the passage-forming section configured to extend from the second end of the stomach towards the first end of the stomach, the passage-forming section configured to form the passage between the first and second portions of the stomach, the passage-forming section having first and second passage-forming arms extending substantially in a direction towards, and substantially collinear with, the partitioning section and at least partially spaced apart at a first location by a second distance greater than the first distance; wherein the first and second passage-forming arms are continuous and at least partially curved, the first passage-forming arm is continuous with the first arm of the partitioning section, and the second passage-forming arm is continuous with the second arm of the partitioning section.
