a shaft moveably positioned within the guide body, the shaft being operably connected to the plurality of needles such that proximal movement of the shaft draws the plurality of needles into the plurality of needle lumens; and

a needle removal device removably attached to the proximal end of the guide body, the needle removal device comprising:

a first member having a first plurality of needle receptacles extending therethrough, the first needle receptacles being configured and positioned to correspond to the plurality of needle lumens of the guide body; and

a second member having a second plurality of needle receptacles extending therethrough, wherein at least one of the first member or the second member is moveable between a first position, wherein the first needle receptacles and the second needle receptacles are substantially aligned, and a second position, wherein the first needle receptacles and the second needle receptacles are substantially unaligned.

2. The device of claim 1 , wherein the first position is configured to allow at least one of the plurality of needles to be moveable within at least one of the first needle receptacles or the second needle receptacles, and wherein the second position is configured to at least partially deform the at least one or more of the plurality of needles between the first member and the second member to substantially lock the one or more needles within at least one of the first needle receptacles or the second needle receptacles.

3. The device of claim 2 , wherein the second position is further configured to allow a user to exert a force in a proximal direction of about one (1) to seventy (70) pound-force on at least one of the plurality of needles to remove the one or more needles from the suturing device.

4. The device of claim 1 , further comprising one or more locking features configured to substantially lock at least one of the first member or the second member in the second position.

5. The device of claim 4 , wherein the one or more locking features comprise a first plurality of teeth on the first member and a second plurality of teeth on the second member, wherein the second plurality of teeth are configured to selectively engage the first plurality of teeth in the second position.

6. The device of claim 4 , wherein the one or more locking features comprise one or more detents.

7. The device of claim 1 , wherein one or more of the first needle receptacles have a generally teardrop-like shape including a first head portion and a first tail portion, and wherein one or more of the second needle receptacles have a generally teardrop-like shape including second head portion and a second tail portion, and wherein the second head portion is generally opposite the first head portion.

8. The device of claim 7 , wherein the first needle receptacles and the second needle receptacles are configured to wedge one or more needles between the first tail portions and the second tail portions.

9. The device of claim 1 , wherein the first member comprises a first ring and the second member comprises a second ring, wherein at least the second ring is rotatable relative to the first ring.

10. The device of claim 9 , wherein the first ring includes a recess configured to receive at least a portion of the second ring.

11. The device of claim 9 , wherein the first ring includes a collar portion configured to at least partially overlap a hub of a suturing device.

12. The device of claim 9 , wherein at least one of the first ring or the second ring includes one or more tabs having a length between about 1-cm to 7-cm.

13. The device of claim 9 , further comprising one or more gripping portions on at least one of the first ring or the second ring, wherein the one or more gripping portions are configured to at least help a user move the at least one of the first ring or the second ring between the first position and the second position.

14. The device of claim 1 , wherein the second member is slidably attached to the first member.

15. The device of claim 14 , wherein at least one of the first member or the second member includes a central opening extending therethrough, wherein the central opening has a generally rounded rectangular geometric shape.

16. The device of claim 14 , further comprising a third member slidably attached to the first member, the third member being generally opposite the second member and having a third plurality of needle receptacles extending therethrough.

17. A method of removing one or more needles from a suturing device having one or more needle lumens, the method comprising:

inserting a suturing device into a patient, the suturing device comprising:

a plurality of needles;

one or more sutures, each of the one or more sutures having an end attached to one of the plurality of needles;

a guide body having a proximal end, a distal end, an internal lumen configured to receive at least a portion of the one or more sutures, and a plurality of needle lumens configured to receive the plurality of needles;

a shaft moveably positioned within the guide body, the shaft being operably connected to the plurality of needles such that proximal movement of the shaft draws the plurality of needles into the plurality of needle lumens; and

a needle removal device removably attached to the proximal end of the guide body, the needle removal device comprising:

a first member having a first plurality of needle receptacles extending therethrough, the first needle receptacles being configured and positioned to correspond to the plurality of needle lumens of the guide body; and

a second member having a second plurality of needle receptacles extending therethrough, wherein at least one of the first member or the second member is moveable between a first position, wherein the first needle receptacles and the second needle receptacles are substantially aligned, and a second position, where in the first needle receptacles and the second needle receptacles are substantially unaligned;

positioning the needle removal device substantially adjacent the proximal end of the suturing device;

drawing one or more of the plurality of needles proximally through one or more of the one or more needle lumens of the suturing device until at least tips of the one or more needles exit from the proximal end of the suturing device;

receiving at least the tips of the one or more needles within one or more of the first plurality of needle receptacles and one or more of the second plurality of needle receptacles;

moving at least one of the first member or the second member to the second position to at least partially deform at least a portion of the one or more needles between the first member and the second member; and

moving the needle removal device proximally relative to the suturing device to remove the one or more needles from the suturing device.
