Abstract
The present application provides methods and devices for inducing weight loss. In particular, the present application provides methods for modifying a duodenum to induce weight loss.
Claims37
A method for inducing weight loss in a patient comprising the steps of:
- (i) accessing an intestine having a proximal end, a distal end, an outer surface, and an original lumen extending therethrough;
- and
- (ii) bringing intestinal tissue from different locations on the intestine into abutting relationship along at least a portion of the length of the intestine to form a separate channel within the intestine.
A method for inducing weight loss in a patient comprising the steps of:
- (i) grasping an intestine comprising intestinal tissue and having an original lumen across the diameter of said intestine proximate to the distal end of said intestine to bring intestinal tissue from different locations on said intestine into contact;
- wherein said intestine comprises a papilla of vater and a pylorus;
- (ii) employing a tissue-connecting device to attach said intestinal tissue from said different locations on said intestine;
- and
- (iii) continuing to employ said tissue-connecting device to attach intestinal tissue from different locations on said intestine until a location on the outer surface of intestine that is between the papilla of vater and pylorus is reached;
- wherein steps (i)-(iii) result in the formation of two separated channels within the intestine.
3 more elements
A method for inducing weight loss in a patient comprising the steps of:
- (i) positioning a tissue-connecting device at a location between the pylorus and the papilla of vater on the outer surface of an intestine having an original lumen;
- wherein said intestine is connected to a papilla of vater and a Ligament of Treitz;
- (ii) employing said tissue-connecting device in a radial direction towards the center of said intestine to join tissue from different locations on the intestine together by angling said tissue-connecting device distally relative to the pylorus and then employing said tissue-connecting device along a length of the intestine until a location between the papilla of vater and Ligament of Treitz is reached;
- and
- (iii) continuing to employ said tissue-connecting device along a portion of the length of said intestine until a location near the Ligament of Treitz is reached.
2 more elements
A method for inducing weight loss in a patient comprising:
- (i) accessing an intestine comprising intestinal tissue and having a proximal end, a distal end, and an original lumen extending therethrough, wherein said intestine comprises a pylorus and is connected to a papilla of vater and Ligament of Treitz;
- (ii) inserting a medical device into said proximal end of said intestine;
- (iii) engaging intestinal tissue at a location that is between the papilla of vater and the Ligament of Treitz by means of said medical device such that said intestinal tissue becomes removably attached to said medical device;
- and
- (iv) retracting said medical device and said tissue attached thereto to a location within said original lumen that is between the papilla of vater and the pylorus;
- wherein at least a partial circumferential pouch-cuff is formed at said proximal end of said intestine as a result of retracting said endoscopic device.
3 more elements
A system for inducing weight loss in a patient comprising:
- (a) a grasping means for grasping an intestine and bringing intestinal tissue into abutting relationship;
- and
- (b) a connecting device for attaching in abutting relationship tissues to form a common wall which separates an intestine into at least two channels along a portion of a length of the intestine.
