Abstract

A surgical device is disclosed along with methods of using the same. The surgical device may comprise an outer sheath and a collar assembly. The collar assembly may be coupled to the outer sheath and may comprise a first arm coupled to the outer sheath at a first hinge; a second arm coupled to the first arm at a second hinge; and a collar coupled to the second arm. The collar assembly may be movable from an un-deployed position where the first arm and the second arm extend the collar distally from the outer sheath to a deployed position where the collar is aligned with the first channel of the outer sheath. Also, the first arm, the second arm, and the collar may be positioned substantially within a cross-sectional area of a distal end of the outer sheath when the collar assembly is in the un-deployed position.

Claims

1. A surgical device comprising:

an outer sheath,

a collar assembly coupled to the outer sheath, wherein the collar assembly comprises;

a first arm coupled to the outer sheath at a first hinge;

a second arm coupled to the first arm at a second hinge; and

a collar coupled to the second arm; and

wherein the collar assembly is movable from an un-deployed position where the first arm and the second arm extend the collar distally from the outer sheath to a deployed position where the collar is aligned with the first channel of the outer sheath, and wherein a distal cross section of the collar assembly is smaller when the collar assembly is in the deployed position than when the collar assembly is in the un-deployed position.

2. The surgical device of claim 1, wherein the first arm, the second arm, and the collar are positioned substantially within a cross-sectional area of a distal end of the outer sheath when the collar assembly is in the un-deployed position.

3. The surgical device of claim 1, wherein the collar assembly further comprises a spring rod extending from the first arm to at least one of the second arm and the collar, wherein the spring rod biases the collar assembly to the deployed position.

4. The surgical device of claim 1, wherein the collar assembly further comprises a spring rod extending from the first arm to at least one of the second arm and the collar, wherein the spring rod biases the collar assembly to the un-deployed position.

5. The surgical device of claim 4, wherein the collar assembly further comprises a wire extending proximally from at least one of the second arm and the collar through the outer sheath, wherein the wire is configured to transmit a proximally directed force to at least one of the second arm and the collar to move the collar assembly to the deployed position.

6. The surgical device of claim 1, further comprising a suturing applicator distally extendable from a first channel of the outer sheath;

7. The surgical device of claim 6, wherein the suturing applicator is a needle.

8. The surgical device of claim 7, wherein the collar comprises a cap preventing the suturing needle from extending through the cap when the collar assembly is in the deployed position.

9. The surgical device of claim 1, wherein the collar comprises a hollow center aligned with the first channel of the outer sheath and positioned to receive at least a portion of the suturing applicator.

10. The surgical device of claim 1, wherein the collar comprises a cap on a distally oriented side of the hollow center.

11. The surgical device of claim 1, further comprising a first electrode and a second electrode.

12. The surgical device of claim 11, wherein the first electrode and the second electrode are positioned opposite one another when the collar assembly is in the deployed position.

13. The surgical device of claim 11, wherein the first electrode is positioned on the collar and wherein the second electrode is positioned on the first arm.

14. The surgical device of claim 11, wherein the collar assembly is the first electrode and the first arm is the second electrode.

15. A method of using a surgical device comprising an outer sheath;

a suturing needle distally extendable from a first channel of the outer sheath; and

a collar assembly coupled to the outer sheath, wherein the collar assembly comprises;

a first arm coupled to the outer sheath at a first hinge;

a second arm coupled to the first arm at a second hinge; and

a collar coupled to the second arm; and

wherein the collar assembly is movable from an un-deployed position where the first arm and the second arm extend the collar distally from the outer sheath to a deployed position where the collar is aligned with the first channel of the outer sheath, and wherein a distal cross section of the collar assembly is smaller when the collar assembly is in the deployed position than when the collar assembly is in the un-deployed position, the method comprising;

extending the collar and at least a portion of the second arm through an opening in a tissue;

positioning the collar assembly in the deployed position such that the outer sheath is on a first side of the tissue and the collar is on a second side of the tissue; and

extending the suturing needle distally through the tissue.

16. The method of claim 15, further comprising extending the surgical device through a working channel of an endoscope with the collar assembly in the un-deployed position.

17. The method of claim 15, wherein the surgical device comprises:

a spring rod extending from the first arm to at least one of the second arm and the collar, wherein the spring rod biases the collar assembly to the un-deployed position; and

a wire extending proximally from at least one of the second arm and the collar through the outer sheath, wherein the wire is configured to transmit a proximally directed force to at least one of the second arm and the collar to move the collar assembly to the deployed position; and

wherein positioning the collar to the deployed position comprises retracting the wire proximally.

18. The method of claim 15, further comprising extending the suturing needle distally through at least a portion of a cavity of the collar.

19. The method of claim 18, further comprising:

extending the suturing needle distally completely through the cavity of the collar;

deploying a suture anchor from a distal end of the suturing needle; and

pulling the suture anchor proximally with the collar.

20. The method of claim 15, further comprising inserting the surgical device into an endoscope working channel.

21. A method of using a surgical device comprising an outer sheath;

a suturing needle distally extendable from a first channel of the outer sheath; and

a collar assembly coupled to the outer sheath, wherein the collar assembly comprises;

a first arm coupled to the outer sheath at a first hinge;

a second arm coupled to the first arm at a second hinge; and

a collar coupled to the second arm; and

wherein the collar assembly is movable from an un-deployed position where the first arm and the second arm extend the collar distally from the outer sheath to a deployed position where the collar is aligned with the first channel of the outer sheath, and wherein a distal cross section of the collar assembly is smaller when the collar assembly is in the deployed position than when the collar assembly is in the un-deployed position, the method comprising;

placing a portion of tissue between the collar and the outer sheath; and

extending the suturing needle distally through the tissue.

22. The method of claim 21, wherein the surgical device comprises:

a spring rod extending from the first arm to at least one of the second arm and the collar, wherein the spring rod biases the collar assembly to the un-deployed position; and

a wire extending proximally from at least one of the second arm and the collar through the outer sheath, wherein the wire is configured to transmit a proximally directed force to at least one of the second arm and the collar to move the collar assembly to the deployed position; and

wherein the method further comprises exerting a proximally directed force on the wire to clamp the portion of tissue between the collar and the outer sheath.

23. The method of claim 21, wherein the portion of tissue defines an opening, and wherein placing the portion of tissue between the collar and the outer sheath comprises closing the opening between the collar and the outer sheath.

24. The method of claim 21, further comprising extending the suturing needle distally through at least a portion of a cavity of the collar.

25. The method of claim 24, further comprising:

extending the suturing needle distally completely through the cavity of the collar;

deploying a suture anchor from a distal end of the suturing needle; and

pulling the suture anchor proximally with the collar.

26. The method of claim 21, further comprising inserting the surgical device into an endoscope working channel.
