Pyloric valve corking device
First Claim
1. A device for obstructing a gastric opening, comprising:
- an occluding member having an inflated state and an uninflated state, wherein an outer diameter of the occluding member is configured to expand when fluid enters the occluding member and the occluding member is inflated from the uninflated state to the inflated state after deployment, wherein the occluding member is further adapted to collapse from the inflated state back to the uninflated state for removal and wherein the inflated state of the occluding member is a radially expanded shape which inhibits permanent obstruction of the gastric opening;
a bridging member extending from the occluding member, wherein the bridging member has a length adapted to pass at least partially through the gastric opening and to enable the occluding member to obstruct the gastric opening, and wherein the length further maintains a diameter which is sufficient to permit the occluding member and the bridging member to intermittently move relative to the gastric opening without obstructing the gastric opening, wherein the bridging member maintains its shape prior to and after deployment through the gastric opening; and
a second member connected to a distal end of the bridging member, where the second member has a diameter which is relatively larger than the bridging member and smaller than the outer diameter of the occluding member when the occluding member is in the inflated state.

Abstract
Pyloric valve corking devices are disclosed herein that generally include an occluding member, expanding from a first configuration to a larger second configuration, and a bridging member extending from the occluding member. The bridging member has a length that is adapted to pass at least partially through the gastric opening, so to enable the occluding member to obstruct the gastric opening, and that is also adapted to permit the occluding member to intermittently move relative to the gastric opening. A second occluding member may be attached to the distal end of the bridging member. The reduction in flow of gastric contents into the duodenum can be actively regulated using a pump or valve, or can be passively regulated with movements of the occluding device.

41. A system for intermittently obstructing a gastric opening, comprising:
-
a first occluding member and a second member, wherein the first occluding member has an inflated state and an uninflated state, wherein an outer diameter of the first occluding member is configured to expand when fluid enters the occluding member and the occluding member is inflated from the uninflated state to the inflated state after deployment, wherein the first occluding member is further adapted to collapse from the inflated state back to the uninflated state for removal and wherein the inflated state of the first occluding member defines a radially expanded shape which inhibits permanent obstruction of the gastric opening; and a bridging member extending between the first occluding member and the second member, wherein the bridging member has a flexible length adapted to pass through the gastric opening and to enable the first occluding member to obstruct the gastric opening and to be retained by the second member, wherein the bridging member maintains its shape prior to and after deployment, and wherein the bridging member further maintains a diameter which is sufficient to permit the first occluding member and the bridging member to intermittently move relative to the gastric opening without obstructing the gastric opening, and wherein the second member is attached to a distal end of the bridging member and has a diameter which is larger than the diameter of the bridging member and smaller than the outer diameter of the first occluding member when the first occluding member is in the inflated state. - View Dependent Claims (42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73)
