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:

an elongated body having a proximal end and a distal end;

a tissue treatment device attached to the distal end of the elongated body, the tissue treatment device having a first jaw opposite a second jaw, the first jaw and the second jaw being rotatable between a closed position and an open position relative to one another about a first longitudinal axis parallel to a longitudinal axis of the tissue treatment device, each of the first jaw and the second jaw are configured for acquiring tissue in an organ; and

a wire retractor disposed along the tissue treatment device and movable from a delivery configuration to a retraction configuration, the wire retractor forming a loop having a first end anchored to the tissue treatment device, and a second end proximal to the first end and movable along the first longitudinal axis to expand a portion of said loop away from said tissue treatment device.

2. The device of claim 1, further comprising a septum disposed between the first jaw and second jaw, wherein the septum being connected to the first end of the wire retractor.

3. The device of claim 2, wherein when the wire retractor moves from the retraction configuration to the delivery configuration, the wire retractor releases the septum.

4. The device of claim 3, wherein the septum is flexible.

5. The device of claim 1, wherein the device is adapted for use with an endoscope.

6. The device of claim 1, wherein the retractor is made of a nitinol.

7. The device of claim 1, wherein the retractor is made of a stainless steel.

8. The device of claim 1, wherein the second end of the wire retractor is moved distally to expand the loop away from the tissue treatment device.

9. The device of claim 1, wherein the expansion of the loop is adapted to push tissue away from the tissue treatment device.

10. The device of claim 1 wherein the wire retractor has a rectangular cross-section.

11. The device of claim 1, wherein the wire retractor has a circular cross section.

12. The device of claim 1, wherein the tissue treatment device has a hinge supporting the first and second jaws, and the first end of the wire retractor is anchored to the hinge.
