Intra-gastric fastening devices
First Claim
1. A method of anchoring an object to a region of tissue within a hollow body organ, comprising:
- grasping the region of tissue from an interior surface of the hollow body organ;
configuring the region of tissue to create at least one fold of tissue; and
securing a fastener to the fold of tissue by partially piercing the fold of tissue with the fastener such that the object fixedly depends from the fastener and is affixed to the fold of tissue within the hollow body organ.

Abstract
Intra-gastric fastening devices are disclosed herein. Expandable devices that are inserted into the stomach of the patient are maintained within by anchoring or otherwise fixing the expandable devices to the stomach walls. Such expandable devices, like inflatable balloons, have tethering regions for attachment to the one or more fasteners which can be configured to extend at least partially through one or several folds of the patient'"'"'s stomach wall. The fasteners are thus affixed to the stomach walls by deploying the fasteners and manipulating the tissue walls entirely from the inside of the organ. Such fasteners can be formed in a variety of configurations, e.g., helical, elongate, ring, clamp, and they can be configured to be non-piercing. Alternatively, sutures can be used to wrap around or through a tissue fold for tethering the expandable devices. Non-piercing biased clamps can also be used to tether the device within the stomach.

12. A system for occupying a volume within a lumen of a hollow body organ, comprising:
-
a space-occupying member having a tethering region; and
a fastener adapted to be fully secured by partially piercing the fastener through at least one fold of tissue created from an interior surface of the hollow body organ, wherein the tethering region of the space-occupying member is secured to the fastener, which is affixed to the fold of tissue within the hollow body organ. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)
