Abstract

A medical device for managing tissue in an organ, such as the stomach, for retracting or positioning tissue and related organs to allow certain regions of the stomach to be acquired for a gastroplasty procedure. The medical device includes an elongated body having a proximal end and a distal end, and a tissue treatment device attached to the distal end of the elongated body. The tissue treatment device includes a first jaw opposite a second jaw, and each jaw is adapted to acquire tissue. A retractor is disposed along the tissue treatment device and adapted to be moveable from a delivery position to a retraction position to move or manage the tissue of the stomach. The medical device also includes a collapsible barrier disposed between the first and second jaws of the tissue treatment device to direct tissue into the first and second jaws separately.

Claims

1. A device for managing tissue in an organ, comprising:

a flexible, elongated body having a proximal end and a distal end and a working lumen extending therebetween;

a gastroplasty device for tissue acquisition and fixation to create a partition within a hollow body organ disposed at the distal end of the elongated body; and

a retractor formed of elastomeric material connected to the gastroplasty device, the retractor including a cylindrical proximal portion transitioning to a generally flat distal portion, and the flat distal portion connected to a cable and being moveable from a straight position to an arced position to manage tissue of the organ relative to the gastroplasty device when the cable is actuated.

2. The device of claim 1, wherein the retractor includes spring elements disposed within the elastomeric material to bias the retractor into the straight position.

3. The device of claim 2, wherein the spring elements are formed of nitinol.

4. The device of claim 2, wherein the retractor includes guide tubes disposed within the flat portion to house the spring elements.
