Abstract

A system for performing a medical operation includes an end effector having first and second arms, each extending from a distal end to a proximal end, the proximal ends being connected to one another, the end effector being movable between a closed configuration wherein the first and second arms are separated from one another by a first distance and an open configuration wherein the first and second arms are separated from one another by a second distance greater than the first distance, a distance between the first and second arms being substantially constant from the proximal ends to the distal ends, wherein the end effector is biased to the open configuration. A first plate element extends from a first surface configured to engage a first wall of the first arm to a second surface configured to contact target tissue in an operative configuration. A second plate element extends from a first surface configured to engage a first wall of the second jaw to a second surface configured to contact target tissue in an operative configuration.

Claims

1. A system for performing a medical operation, comprising:

an end effector having first and second arms, each extending from a distal end to a proximal end, the proximal ends being connected to one another, the end effector being movable between a closed configuration wherein the first and second arms are separated from one another by a first distance and an open configuration wherein the first and second arms are separated from one another by a second distance greater than the first distance, a distance between the first and second arms being substantially constant from the proximal ends to the distal ends, wherein the end effector is biased to the open configuration;

a first plate element extending from a first surface configured to engage a first wall of the first arm to a second surface configured to contact target tissue in an operative configuration; and

a second plate element extending from a first surface configured to engage a first wall of the second jaw to a second surface configured to contact target tissue in an operative configuration.

2. The system of claim 1, wherein the proximal ends of each arm are integral to one another.

3. The system of claim 1, wherein the end effector includes a clipping device.

4. The system of claim 1, further comprising a capsule housing a proximal portion of the end effector therewithin.

5. The system of claim 1, further comprising a first protrusion on the second surface of the first plate element.

6. The system of claim 5, further comprising a second protrusion on the second surface of the second plate element.

7. The system of claim 6, wherein the second protrusion is configured to interlink with the first protrusion to apply a constrictive pressure to target tissue captured therebetween when the end effector is in the closed configuration.

8. The system of claim 7, further comprising a recess formed on the second surface of the second plate element, the recess being configured to receive the first protrusion therein to apply a constrictive pressure to target tissue captured therebetween when the end effector is in the closed configuration.

9. The system of claim 1, wherein the first surface of the first plate element comprises a first groove configured to lockingly engage an extension portion of the first arm and the first surface of the second plate element comprises a second groove configured to lockingly engage an extension portion of the second arm.

10. The system of claim 1, wherein the first and second plate members are substantially planar.

11. The system of claim 1, further comprising a locking arrangement configured to lock the first plate element to the second plate element in the closed configuration.

12. The system of claim 11, wherein the locking arrangement comprises a tab extending from a distal end of the first plate element, the tab being configured to lockingly grip the first surface of the second plate element when moved to the closed configuration.

13. The system of claim 1, wherein the first plate element is integrally formed with the second plate element.

14. The system of claim 1, wherein the first plate element is connected to the second plate element by a hinge.

15. The system of claim 1, further comprising a slot extending through the first and second plate elements and the end effector, the slot configured to permit insertion of a cutting device therethrough.

16. A medical device, comprising:

a first plate element extending from a first surface configured to engage a first wall of a first arm of an end effector to a second tissue-contacting surface; and

a second plate element extending from a first surface configured to engage a first wall of a second arm of the end effector to a second tissue contacting surface, wherein the first and second arms of the end effector are connected to one another at a proximal end and are movable between a closed configuration wherein the first and second arms are separated from one another by a first distance and an open configuration wherein the first and second arms are separated from one another by a second distance greater than the first distance, a distance between the first and second arms being substantially constant from the proximal ends to the distal ends.

17. The device of claim 16, further comprising a first protrusion on the second surface of the first plate element.

18. The device of claim 17 further comprising a second protrusion on the second surface of the second plate element.

19. The device of claim 18, wherein the second protrusion is configured to interlink with the first protrusion to apply a constrictive pressure to target tissue captured therebetween when the end effector is in the closed configuration.

20. The device of claim 19, further comprising a recess formed on the second surface of the second plate element, the recess being configured to receive the first protrusion therein to apply a constrictive pressure to target tissue captured therebetween when the end effector is in the closed configuration.

21. The device of claim 17, wherein the first protrusion is one of linear, curved, S-shaped, serpentine and zig-zagged.

22. The device of claim 16, wherein the first surface of the first plate element comprises a groove configured to lockingly engage an extension portion of the first jaw.

23. The device of claim 16, wherein the first plate member is substantially planar.

24. The device of claim 16, further comprising a locking arrangement configured to lock the first plate element to the second plate element in the closed configuration.

25. The device of claim 24, wherein the locking arrangement comprises a tab extending from a distal end of the first plate element.

26. The device of claim 25, wherein the tab is configured to lockingly grip the first surface of the second plate element when moved to the closed configuration.

27. The device of claim 16, wherein the first plate element is integrally formed with the second plate element.

28. The device of claim 16, wherein the first plate element is connected to the second plate element by a hinge.

29. The device of claim 16, wherein the first plate element is slidably receivable over the first jaw.

30. The device of claim 29, wherein the first plate element comprises an opening configured to receive the first jaw therethrough.

31. A method for deploying a medical device in a living body, comprising the steps of:

advancing a device to a target position in a living body, the device having a first channel extending longitudinally therethrough and having an end effector positioned therein, the end effector having at least two arms, each extending from a distal end to a proximal end, first and second plates connected to an inner surface of each arm respectively, and configured to contact target tissue in an operative configuration, wherein a distance between the first and second plates is substantially constant along a length thereof;

deploying the end effector at a target location in the body so that one of a blood vessel, duct and an organ is captured between the first and second plate elements; and

moving the end effector to the closed configuration, the movement causing the first and second plate elements to apply a constrictive pressure to the selected one of the blood vessel, duct and organ and prevent a flow of fluid therethrough.
