Abstract

Some disclosed suture securement devices comprise a flat, thin, generally planar body that has one or more suture engagement slots extending into the body from a perimeter inlet for receiving sutures laterally into the device. The slots can be resiliently widened to receive a suture and then released to clamp onto the suture. Some embodiments include two or more such suture engagement slots that independently receive and secure different sutures. Some embodiments include one or more locking tabs that have a closed position that retains the slots against widening and blocks the inlet to the slot. In some embodiment two or more slots are position next to each other on the same side of the device, while in other embodiments slots are positioned on opposite sides of the device. Other types of suture securement devices are also disclosed.

First claim

1 . A device for securing sutures, comprising:
a flat, thin, generally planar body comprising a resiliently deformable material; a first suture engagement slot in the body that extends into the body from a first inlet at a perimeter of the body; and a second suture engagement slot in the body that extends into the body from the first inlet or from a second inlet at the perimeter of the body; wherein the first and second suture engagement slots are each configured to receive a suture through an associated inlet and are configured to apply a pinching force to the suture when received in the slot such that the device secures to the suture and resists the suture from moving axially through the device along a longitudinal axis of the suture and resists the suture from moving laterally out of the device through the associated inlet.

2 . The device of claim 1 , wherein the first and second suture engagement slots have a jagged or wavy shape.

3 . The device of claim 1 , wherein the body comprises openings in the body on opposing sides of the first and second suture engagement slots that allow a delivery device to apply a separation force to the clip that widens the first and second suture engagement slots.

4 . The device of claim 1 , wherein the first and second suture engagement slots are generally parallel to each other.

5 . The device of claim 1 , wherein the first and second suture engagement slots are positioned side-by-side and the first and second inlets are adjacent to each other on one side of the perimeter.

6 . The device of claim 1 , wherein the first and second suture engagement slots are positioned opposite sides of the device and the first and second inlets are positioned opposite sides of the perimeter.

7 . The device of claim 1 , wherein inner ends of the first and second suture engagement slots join relief slots in the body that reduce stress concentrations in the body when the first and second suture engagement slots are widened.

8 . The device of claim 1 , wherein the body includes at least a first locking tab that has a closed position wherein at least the first suture engagement slot is retained against widening and at least the first inlet is blocked.

9 . The device of claim 1 , wherein the body includes a first locking tab that has a closed position wherein the first suture engagement slot is retained against widening, and wherein the body includes a second locking tab that has a closed position wherein the second suture engagement slot is retained against widening.

10 . The device of claim 1 , wherein the first locking tab has two or more closed positions wherein an associated suture engagement slot is retained against widening, and the associated suture engagement slot has a different width when the first locking tab is in each of the two or more closed positions.

11 . A device for securing sutures, comprising:
a flat, thin, generally planar body comprising a resiliently deformable material; a suture engagement slot in the body that extends into the body from an inlet at a perimeter of the body, wherein the suture engagement slot is configured to receive a suture laterally through the inlet and is configured to apply a pinching force to the suture such that the device secures to the suture and resists the suture from moving axially through the device along a longitudinal axis of the suture; and a locking tab that has an open position wherein the suture engagement slot is permitted to widen such that a suture can enter laterally through the inlet into the suture engagement slot, and the locking tab has a closed position wherein the suture engagement slot is retained against widening and the first inlet is blocked.

12 . The device of claim 11 , wherein the locking tab has two or more different closed positions that each correspond a different maximum width of the suture engagement slot.

13 . The device of claim 11 , wherein the locking tab forms a ratcheting mechanism to allow the locking tab to move from a first closed position to a second closed position by applying a compression force on the device, wherein the suture engagement slot has a smaller width in the second closed position compared to the first closed position.

14 . The device of claim 11 , further comprising a second locking tab.

15 . The device of claim 11 , wherein the locking tab is resiliently deformed in the open position and is biased toward the closed position.

16 . The device of claim 11 , further comprising a second suture engagement slot in the body, and wherein the locking tab retains the second suture engagement slot against widening when the locking tab is in the closed position.

17 . A device for securing sutures, comprising:
an annular body that defines an axial dimension passing through the annular body and a radial dimension perpendicular to the axial dimension, the annular body being resiliently compressible and expandable in the radial dimension; and a plurality of suture engagement members that extend from one axial side of the annular body and that each comprise a free end that projects radially inwardly, such that a suture engagement opening is formed between the free ends of the plurality of suture engagement members; wherein the device has an open state wherein the annular body is resiliently deformed and the free ends of the plurality of suture engagement members are spaced apart from each other to allow a suture to enter into the suture engagement opening; and wherein the device has a closed state wherein the annular body is released and the free ends of the plurality of suture engagement members are adjacent to each other such that a suture positioned in the suture engagement opening is secured.

18 . The device of claim 17 , wherein radially compressing the annular body causes the free ends of the suture engagement members to move apart from each other to allow a suture to enter into the suture engagement opening.

19 . The device of claim 17 , wherein the annular body has a zigzag shape.

20 . The device of claim 17 , wherein the free ends of the suture engagement members taper in width moving radially inwardly.
