Abstract
The present invention provides a device for causing weight loss in obese patients comprising an implant that creates an intestinal bypass between a first region of intestine and a second region of intestine. In one embodiment, the implant comprises an adjustable opening to adjust the fraction of food material passing through the intestinal bypass. Also disclosed is a method for causing weight loss in obese patients comprising the steps of surgically creating an intestinal bypass with an adjustable opening, calculating an expected weight loss and an expected electrolyte balance in the patient, periodically monitoring the patient'"'"'s weight loss and electrolyte balance and adjusting the size of the adjustable opening if necessary.

31. A method for causing weight loss in obese humans comprising the steps of:
-
a. surgically creating an intestinal bypass with an adjustable opening, the intestinal bypass having an initial bypass opening size, b. calculating a time for a followup, c. calculating a desired weight loss of the patient till the followup, d. calculating a desired electrolyte balance of the patient, e. calculating actual weight loss and actual electrolyte balance during the followup, f. if the actual weight loss and the actual electrolyte balance match the desired weight loss and the desired electrolyte balance respectively;
i. calculating a time for a next followup, ii. calculating a desired weight loss of the patient till the next followup, and iii. calculating a desired electrolyte balance of the patient,
elsei. calculating a new bypass opening size based on the desired weight loss, the actual weight loss, the desired electrolyte balance and the actual electrolyte balance, ii. changing bypass opening size to the new bypass opening size, iii. calculating a time for a followup, iv. calculating a desired weight loss of the patient till the followup, and v. calculating a desired electrolyte balance of the patient and g. repeating steps (e) through (f). - View Dependent Claims (32)
