Abstract
The invention relates to a method and apparatus for endoscopically shaping and standardizing the size of a sleeved stomach for use in gastric reduction surgery. The device and method standardize and streamline gastric reduction surgery, specifically vertical sleeve gastrectomy, providing a guide for creating the stomach reduction and also shaping a stomach which will maintain an appropriate structure post-surgery.
Claims20
A method of treating a patient, the method comprising the steps of:
- inserting a cylindrical sheath of gastric reduction surgery assistance apparatus through the patient's mouth and into the patient's esophageal tract;
- deploying a balloon from the cylindrical sheath into the patient's stomach, wherein the balloon includes a plurality of channel openings extending through the balloon from a converged channel within the balloon;
- inflating the balloon within the patient's stomach;
- sealing the balloon against the patient's stomach's inner walls;
- excising at least a portion of the patient's stomach;
- and
- removing the balloon and the cylindrical sheath of the gastric reduction surgery assistance apparatus from the patient.
