Abstract

A system for tissue approximation and fixation is described herein. A device is advanced in a minimally invasive manner within a patient'"'"'s body to create one or several divisions or plications within a hollow body organ. The system comprises a stapler assembly having a tissue acquisition member and a tissue fixation member. The stapler assembly approximates tissue from within the hollow body organ with the acquisition member and then affixes the approximated tissue with the fixation member. In one method, the system can be used as a secondary procedure to reduce the size of a stoma within the hollow body organ.

Claims

1. A tissue fixation device, comprising:

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

a tissue fixation assembly connected to the distal end of the elongated body having an acquisition member for acquiring tissue and a fixation member having staples for stapling tissue acquired by the acquisition member;

wherein the acquisition member is integrated into a portion of the fixation member and wherein the acquisition member defines at least one opening adapted to adhere tissue thereto via a vacuum; and

wherein a hinge member pivotally connects the fixation assembly to the distal end of the elongated body.

2. The device of claim 1, further comprising at least one vacuum tubing positioned along at least a portion of the elongated body.

3. The device of claim 1, wherein the acquisition member is a vacuum pod permanently attached to at least a portion of the fixation assembly.

4. The device of claim 1, wherein the fixation assembly includes an atraumatic distal tip.

5. The device of claim 4, wherein the distal tip defines a guide wire lumen therethrough.

6. The device of claim 1, wherein the elongated body is configured to be curved.

7. The device of claim 1, further comprising a handle connected to the proximal end of the elongated body.

8. The device of claim 7, wherein the handle includes at least one actuation mechanism adapted to articulate the fixation assembly from a first configuration to a second configuration.

9. The device of claim 7, wherein the handle is adapted to deploy a plurality of staples from the fixation assembly.

10. The device of claim 1, wherein the fixation assembly comprises a staple cartridge and an anvil in apposition to the staple cartridge.

11. The device of claim 10, wherein the staple cartridge is adapted to rotate about a pivot relative to the anvil from a closed configuration to an open configuration.

12. The device of claim 10, wherein the anvil is adapted to rotate about a pivot relative to the staple cartridge from a closed configuration to an open configuration.

13. The device of claim 1, wherein the acquisition member is a mechanical device.

14. The device of claim 13, wherein the mechanical device is a grasper having a cable and a claw disposed at the distal end of the cable.
