Abstract

Methods and devices for use in tissue approximation and fixation are described herein. The present invention provides, in part, methods and devices for acquiring tissue folds in a circumferential configuration within a hollow body organ, e.g., a stomach, positioning the tissue folds for affixing within a fixation zone of the stomach, preferably to create a pouch or partition below the esophagus, and fastening the tissue folds such that a tissue ring, or stomas, forms excluding the pouch from the greater stomach cavity. The present invention further provides for a liner or bypass conduit which is affixed at a proximal end either to the tissue ring or through some other fastening mechanism. The distal end of the conduit is left either unanchored or anchored within the intestinal tract. This bypass conduit also includes a fluid bypass conduit which allows the stomach and a portion of the intestinal tract to communicate.

Claims

1. A system for bypassing a hollow body organ, comprising:

a tissue approximation and fixation apparatus having an elongate outer tubular member defining at least a first lumen therethrough, the elongate outer tubular member having a plurality of rings, the rings having one or more pivots for facilitating relative motion therebetween, and an elongate inner tubular member defining at least a second lumen therethrough and slidingly disposed throughout the first lumen such that a distal portion of the inner tubular member extends partially beyond a distal end of the outer tubular member, and the tissue approximation and fixation apparatus having a fastening device attached to the distal end of the inner tubular member, wherein the fastening device defines a circumferential receiving surface about the inner tubular member, and wherein the fastening device further defines at least one port in fluid communication with the second lumen of the inner tubular member, wherein an enclosable channel is defined about the distal portion of the inner tubular member when the receiving surface of the fastening device is positioned adjacently to the distal end of the outer tubular member;

a bypass conduit having a tubular member with a proximal end and a distal end which defines a main lumen therethrough, wherein the main lumen maintains communication from proximal to distal of the hollow body organ, and wherein at least a portion of an outer surface of the tubular member is adapted to maintain fluid communication therealong;

wherein the tissue approximation and fixation device forms a narrowed region within the hollow body organ and the bypass conduit is affixed to the narrowed region of the hollow body organ.

2. The system of claim 1, wherein the outer surface of the tubular member of the bypass conduit defines at least one channel along at least the portion of the outer surface.

3. The system of claim 2, wherein the at least one channel of the bypass conduit maintains fluid communication between the hollow body organ and a region distal of the hollow body organ through the at least one channel of the bypass conduit.

4. The system of claim 2, wherein the tubular member of the bypass conduit further defines a plurality of additional channels along the outer surface of the tubular member of the bypass conduit.

5. The system of claim 2, wherein the at least one channel of the bypass conduit extends between the hollow body organ and a region distal of the hollow body organ.

6. The system of claim 2, wherein the at least one channel of the bypass conduit extends between a first region distal of the hollow body organ and a second region distal of the first region.

7. The system of claim 2, wherein the at least one channel of the bypass conduit extends along a length of the tubular member of the bypass conduit.

8. The system of claim 2, wherein the at least one channel of the bypass conduit is defined longitudinally along the outer surface of the tubular member of the bypass conduit.

9. The system of claim 1, further comprising one or more cables coupled to the elongate outer tubular member and configured to control locations of the plurality of rings.

10. The system of claim 1, wherein the receiving surface of the fastening device is formed at an angle relative to a longitudinal axis of the elongate outer tubular member and the distal end of the outer tubular member is formed at a complimentary angle to the angle of the receiving surface of the fastening device.

11. The system of claim 1, wherein one or more of:

the fastening device, a distal portion of the elongate inner tubular member, and a distal portion of the elongate outer tubular member further comprises a plurality of ports formed thereon.
