Abstract

Devices, systems, and methods are provided for managing suture filament during a tissue repair procedure. One exemplary embodiment of an anchor insertion tool includes a handle, an elongate shaft extending distally from the handle, and a ring disposed around the elongate shaft. The ring can be configured to slide along a length of the shaft, and can be configured to engage a filament extending from an anchor removably coupled to the shaft's distal end during a suture anchor insertion procedure. In some embodiments, the ring can include one or more slots for receiving a filament and maintaining a tension applied to the filament. The ring can also include features that prevent it from rotating with respect to the shaft, such as a boss formed on a ring's central opening that engages a slot formed in the shaft. Other devices, systems, and methods for suture anchor insertion are also provided.

First claim

What is claimed is:

1 . A suture anchor insertion assembly, comprising:
a handle; an elongate shaft extending distally from the handle, the elongate shaft having a channel formed along at least a portion of a length of the elongate shaft and a distal end in communication with the channel that is configured to engage a suture anchor; and a ring slidably disposed around the elongate shaft through a central opening formed in the ring, the ring being defined between an inner portion and an outer portion such that the central opening has a substantially uniform inner diameter that extends continuously through the inner and the outer portion, the outer portion having a plurality of slots formed therein that are configured to engage a plurality of suture filaments extending from a suture anchor engaged by the distal end of the elongate shaft, the plurality of suture filaments extending from a slot of the shaft, wherein the ring is configured such that a first filament of the plurality of suture filaments can be disposed in the plurality of slots to maintain at least one of a position or a tension thereof while a second filament of the plurality of filaments can be manipulated in conjunction with using the second filament to perform at least a portion of a surgical procedure at a surgical site.

2 . The insertion assembly of claim 1 , wherein each slot of the plurality of slots extends from the outer portion towards the inner portion and across a width of the outer portion to separate adjacent portions of the sidewall of the outer portion such that a valley is defined between the adjacent portions.

3 . The insertion assembly of claim 2 , wherein a width of each slot at the outer portion is greater than the width of the slot more proximate to the inner portion.

4 . The insertion assembly of claim 1 , further comprising a threader having an opening configured to receive the plurality of suture filaments therethrough.

5 . The insertion assembly of claim 4 , wherein a distal end of the threader that includes the opening is disposed distal of a suture anchor engaged with the distal end of the elongate shaft and a proximal end of the threader that includes a handle is disposed proximal of the ring, with an intermediate portion of the threader disposed between the distal end of the threader and the proximal end of the threader passes through the central opening of the ring, through the channel of the elongate shaft, and through the suture anchor engaged with the distal end of the elongate shaft.

6 . The insertion assembly of claim 1 , wherein the plurality of suture filaments extend out of the channel at a location proximate to the inner portion of the ring.

7 . The insertion assembly of claim 1 , wherein the elongate shaft and the ring are configured such that a distance between the distal end of the elongate shaft and the ring increases when a suture anchor engaged by the distal end of the elongate shaft is advanced away from the handle.

8 . The insertion assembly of claim 1 , wherein the ring is configured to slide along a length of the elongate shaft to apply tension to the plurality of suture filaments when a suture anchor engaged by the distal end of the elongate shaft is driven into bone.

9 . The insertion assembly of claim 1 , wherein the ring is configured to slide along a length of the elongate shaft to apply tension to the plurality of suture filaments when the elongate shaft is moved laterally with respect to the ring.

10 . The insertion assembly of claim 1 , wherein a length of each slot of the plurality of slots is approximately equal to a distance between a top surface of the inner portion of the ring and a top surface of the outer portion of the ring.

11 . The insertion assembly of claim 1 , wherein the plurality of slots are disposed approximately equidistantly around a circumference of the ring.

12 . The insertion assembly of claim 1 , wherein the ring is non-rotatably coupled to the elongate shaft.

13 . The insertion assembly of claim 12 , wherein the ring includes a boss formed in the central opening that is configured to engage a portion of the elongate shaft to prevent rotation of the ring with respect to the elongate shaft.

14 . The insertion assembly of claim 1 , wherein a width of a slot of the plurality of slots proximate to the outer portion of the ring is greater than a width of the slot at a terminal end of the slot that is located distal of the outer portion of the ring.

15 . The insertion assembly of claim 1 , wherein a height of the outer portion of the ring is greater than a height of the inner portion of the ring.

16 . A suture filament organizer, comprising:
a sidewall that extends between an outer portion and an inner portion having a central opening formed therein, the central opening having a substantially uniform inner diameter that extends continuously through the outer portion and the inner portion, the outer portion concavely extending towards the inner portion and having one or more cutouts formed therein with the one or more cutouts extending across a length of the outer portion and across a width of the outer portion to separate adjacent portions of the sidewall of the outer portion such that a valley is defined between the adjacent portions; and a boss formed on a circumference of the central opening that is configured to engage a portion of a shaft of an insertion tool to prevent rotation of the sidewall with respect to the insertion tool.

17 . The organizer of claim 16 , wherein a length of the one or more cutouts is approximately equal to a distance between a top surface of the inner portion and a top surface of the outer portion.

18 . The organizer of claim 16 , wherein the one or more cutouts comprises a plurality of cutouts formed around a circumference of the sidewall.

19 . The organizer of claim 16 , wherein a width of each cutout of the one or more cutouts at the outer portion is greater than the width of the cutout more proximate to the inner portion.
