Device for insufflating the interior of a gastric cavity of a patient
A method for laparoscopically preventing insufflation of the small bowel during gastric procedures includes applying an obstruction member at the pyloric sphincter to block the passage of gas from the gastric cavity into the small bowel and insufflating the gastric cavity.
1. A method for laparoscopically preventing insufflation of a small bowel during gastric procedures, comprising: applying an obstruction member at a pyloric sphincter to block passage of gas from a gastric cavity into the small bowel; insufflating the gastric cavity; and further including the step of inserting a tube into and through the pyloric sphincter, and venting or suctioning any gas that passes into the small bowel.
2. The method according to claim 1 , wherein the tube is inserted laparoscopically.
3. The method according to claim 1 , wherein the obstruction member consists of a fluid injected into the pyloric sphincter.
4. The method according to claim 3 , wherein the fluid is an absorbable material.
5. The method according to claim 1 , wherein the step of applying an obstruction member includes forming a fold in tissue of the pyloric sphincter effectively blocking passage of gas from the gastric cavity into the small bowel.
6. The method according to claim 1 , wherein the step of applying an obstruction member includes applying an external clamp to the pyloric sphincter, the clamp applying a compression load on tissue to seal the small bowel from gas being applied to gastric cavity.
