Abstract

A needle removal device is provided for removing needles from suturing devices and/or systems. In an embodiment, the needle removal device may be intended for use with a suturing device having one or more needle lumens. The needle removal device may include a first member having a first plurality of needle receptacles extending therethrough. The first needle receptacles may be configured and positioned to correspond to one or more of the one or more needle lumens of the suturing device. The needle removal device may also include a second member having a second plurality of needle receptacles extending therethrough. At least one of the first member or the second member may be 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 substantially unaligned.

First claim

What is claimed is:

1. A needle removal device intended for use with a suturing device, the suturing device having one or more needle lumens, 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 one or more of the one or more needle lumens of the suturing device; 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, where the first needle receptacles and the second needle receptacles are substantially aligned, and a second position, where the first needle receptacles and the second needle receptacles are substantially unaligned wherein the first position is configured to allow one or more 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 one or more 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.

2. The device of claim 1 , wherein the second position is further configured to allow a user to exert a force in a proximal direction of about one (1) to sixty (60) pound-force on the one or more needles to remove the one or more needles from the suturing device.

3. The device of claim 1 , wherein the second position is further configured to allow a user to exert a force in a proximal direction of about one quarter (0.25) to seventy (70) pound-force on the one or more needles to remove the one or more needles from the suturing device.

4. The device of claim 1 , wherein the second position is further configured to allow a user to exert a force in a proximal direction of about five (5) to forty (40) pound-force on the one or more needles to remove the one or more needles from the suturing device.

5. The device of claim 1 , further comprising one or more complementary features configured to maintain a relative position of the first member to the second member.

6. The device of claim 1 , wherein movement between the first position and the second position includes sliding of at least one of the first member or the second member.

7. The device of claim 1 , wherein the first member and the second member each include a central aperture.

8. 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, 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.

9. The device of claim 8 , wherein the one or more locking features comprise one or more detents.

10. 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.

11. The device of claim 10 , 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.

12. 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.

13. The device of claim 12 , wherein the first ring includes a recess configured to receive at least a portion of the second ring.

14. The device of claim 12 , wherein the first ring includes a collar portion configured to at least partially overlap a hub of a suturing device.

15. The device of claim 12 , 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.

16. The device of claim 12 , 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.

17. The device of claim 1 , 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.
