RE-SHAPING INTRAGASTRIC IMPLANTS
First Claim
1. An intragastric obesity treatment implant that stimulates the stomach walls, comprising:
- an inflatable member having an inflated size that will not pass through the pyloric sphincter and a volume within the stomach of at least 400 ml and being made of a material that will resist degradation over a period of at least six months within the stomach, the inflatable member being formed as a substantially planar disc having opposed faces and a peripheral surface and a maximum width larger than the contracted width of an adult stomach so alter the shape of the stomach to conform somewhat to the inflatable member,the implant being formed of a material which permits it to be compressed when deflated into a substantially linear delivery configuration.

Abstract
The present application provides implantable intragastric devices for the treatment of obesity. The intragastric devices advantageously act as a volume-occupying device, and is able to survive implantation in a patient'"'"'s stomach for a year or longer. In addition, the intragastric devices may be configured to stimulate an inner stomach wall and/or temporarily block the pylorus to slow gastric emptying and/or be rotationally variant, thereby encouraging different stimulation points on the inner wall of the stomach and limiting the stomach'"'"'s ability to adapt over long term implantation. The intragastric devices may reshape the stomach cavity, such as by pushing on opposite sides so as to “planarize” the stomach. For instance, the device may be an inflated disk, or an implantable loop or a springy coil that may be straightened for delivery/extraction yet assume the loop or coil shape upon implant.

7. An intragastric obesity treatment implant that stimulates the stomach walls, comprising:
an elongated member having a relaxed configuration that forms a coil, opposite free ends of the coil overlapping one another to permit constriction of the coil, the coil having a diameter that generally fits within the stomach of an adult patient so as to contact the interior stomach walls upon contraction thereof, the elongated member being formed of a material which permits it to be stretched into a substantially linear delivery configuration and that will resist degradation over a period of at least six months within the stomach. - View Dependent Claims (8, 9, 10, 11, 12, 13)

14. An intragastric obesity treatment implant that stimulates the stomach walls, comprising:
an elongated hollow member having a relaxed configuration that forms a loop, opposite free ends of the loop being adapted to connect together, the loop having a diameter that generally fits within the stomach of an adult patient so as to contact the interior stomach walls upon contraction thereof, the elongated hollow member being formed of a material which permits it to be stretched into a substantially linear delivery configuration and that will resist degradation over a period of at least six months within the stomach. - View Dependent Claims (15, 16, 17, 18, 19)
