Abstract
A method for intraluminally performing a gastric bypass surgery is provided. Two anastomosis members are inserted transorally and located in a proximal position and a distal position within the digestive system. The stomach and the small intestine are transected to create a gastric pouch, a drainage loop, and a Roux limb. The distal anastomosis member joins the drainage loop to a distal portion of the intestine, and the proximal anastomosis member joins the Roux limb to the gastric pouch.
Claims21
A method for performing a gastric bypass procedure on a patient, the method comprising:
- a. introducing a distal anastomosis member transorally into a patient and advancing it to a distal location of the intestine;
- b. introducing a proximal anastomosis member transorally into a patient and advancing it to a proximal location of the intestine;
- c. transecting the intestine proximal to the proximal anastomosis member, thereby creating a drainage loop;
- d. introducing an anastomosis instrument transorally into a patient and into the drainage loop and creating an anastomosis between the drainage loop and the distal portion of the intestine by engaging the anastomosis instrument with the distal anastomosis member;
- e. transecting the stomach to create a gastric pouch proximal to the drainage loop;
- and
- f. introducing the anastomosis instrument transorally into a patient and into the gastric pouch and creating an anastomosis between the gastric pouch and the proximal portion of the intestine by engaging the anastomosis instrument with the proximal anastomosis member.
A method for performing a gastric bypass procedure on a patient, the method comprising:
- a. introducing a distal anvil transorally into a patient and advancing it to a distal location of the intestine;
- b. introducing a proximal anvil transorally into a patient and advancing it to a proximal location of the intestine;
- c. transecting the intestine proximal to the proximal anvil, thereby creating a drainage loop;
- d. introducing a circular stapler transorally into a patient and into the drainage loop and creating an anastomosis between the drainage loop and the distal portion of the intestine by attaching the stapler to the distal anvil and firing the stapler;
- e. transecting the stomach to create a gastric pouch proximal to the drainage loop;
- and
- f. introducing a circular stapler transorally into a patient and into the gastric pouch loop and creating an anastomosis between the gastric pouch and the proximal portion of the intestine by attaching the stapler to the proximal anvil and firing the stapler.
A method for performing a gastric bypass procedure on a patient, the method comprising:
- a. introducing a distal anastomosis member transorally into a patient and advancing it to a distal location of the intestine;
- b. introducing a proximal anastomosis member transorally into a patient and advancing it to a proximal location of the intestine;
- c. accessing the interior of the patient through an incision and introducing a surgical cutter therethrough, and thereafter transecting the intestine proximal to the proximal anastomosis member with the surgical cutter, thereby creating a drainage loop;
- d. introducing an anastomosis instrument transorally into a patient and into the drainage loop and creating an anastomosis between the drainage loop and the distal portion of the intestine by engaging the anastomosis instrument with the distal member;
- e. accessing the interior of the patient through an incision and introducing a surgical cutter therethrough, and thereafter transecting the stomach with the surgical cutter to create a gastric pouch proximal to the drainage loop;
- and
- f. introducing an anastomosis instrument transorally into a patient and into the gastric pouch and creating an anastomosis between the gastric pouch and the proximal portion of the intestine by engaging the instrument with the proximal member.
