Abstract

Methods and devices are provided for reconfiguring a tissue within a hollow body organ using an entirely endoscopic approach in order to effectively reduce flow of fluid contents into a second hollow body organ in fluid communication with the first.

Claims

1. A device for tissue reconfiguration, comprising:

an elongate member having first and second opposable tissue retrieving members disposed on a distal portion thereof, the opposable tissue retrieving members being configured to receive tissue therebetween;

at least one vacuum suction member disposed on at least one of the opposable tissue retrieving members and configured to retrieve a portion of tissue to be reconfigured using negative pressure and to position the portion of tissue between the opposable tissue retrieving members; and

a fastener delivery member disposed on one of the opposable tissue retrieving members and configured to deliver a fastener into a portion of tissue positioned between the opposable tissue retrieving members to reconfigure the portion of tissue;

wherein the opposable tissue retrieving members are movable relative to a proximal portion of the elongate member between an open, grasping configuration and a closed, fastening configuration.

2. The device of claim 1, wherein the at least one vacuum suction member is configured to retrieve and position tissue between the opposable tissue retrieving members when the opposable tissue retrieving members are in the open, grasping configuration.

3. The device of claim 1, wherein the fastener delivery member is configured to deliver a fastener into tissue when the opposable tissue retrieving members are in the closed, fastening configuration.

4. The device of claim 1, wherein the fastener delivery member is a stapler and the fastener is a staple.

5. The device of claim 1, wherein the at least one vacuum suction member is configured to retrieve a portion of tissue from inside a stomach.
