A method for inducing malabsorption in a small intestine of a patient may involve advancing a portion of a catheter into the patient's small intestine and expanding a portion of the catheter to apply force to the small intestine's inner wall to modify mucosal villi and/or crypts. The method for causing weight loss in a patient may also involve dilating at least a portion of the patient's small intestine to modify mucosal villi and/or crypts, destroying mucosal villi and/or crypts of the patient's small intestine using a combined coaxial and radial catheterization of the intestine, or isolating a length of the patient's small intestine and delivering a substance to the isolated length to destroy mucosal villi and/or crypts. |
