Bone anchor including only suture material and delivery device thereof
A suture anchor includes a tubular anchor body made of suture material, the tubular anchor body having a partially open distal tip and a bore extending through the tubular anchor body to a proximal end of the tubular anchor body and a suture woven from the distal tip and extending through the bore and exiting through the proximal end, the suture forming a suture loop outside of the distal tip. The tubular anchor body is configured such pulling an end of the suture at the proximal end causes the tubular anchor body to collapse.
1. A suture anchor delivery device, comprising:
a handle assembly, comprising:
a handle portion;
a trigger, pivotably attached to the handle portion; and
a tubular shaft extending through the handle assembly; and
a draw bar assembly retractably disposed within the handle assembly, the draw bar assembly comprising:
a draw bar tube extending through the tubular shaft, the draw bar tube having a channel disposed through the draw bar tube configured to receive a suture;
a draw bar housing disposed at a first end of the tubular shaft, the draw bar housing having a cutout configured to receive an end of the suture such that the end of the suture wraps around the cutout; and
a draw bar disposed within the draw bar tube and configured to receive a suture anchor mounted on a tip of the draw bar,
wherein upon actuating the trigger the entire draw bar assembly is retracted.
2. The suture anchor delivery device according to claim 1 , wherein the draw bar assembly further comprises a flat portion extending along a bottom of the draw bar housing for orienting the draw bar housing within the handle portion.
3. The suture anchor delivery device according to claim 1 , wherein the draw bar assembly further comprises a stop member configured to prevent the draw bar assembly from being completely removed from the handle portion.
4. A suture delivery system, comprising:
a suture anchor having a tubular anchor body made of suture material, the tubular anchor body having a distal tip and a bore extending through the tubular anchor body to a proximal end of the tubular anchor body;
a suture woven from the distal tip and extending through the bore and exiting through the proximal end; and
a delivery device, comprising:
a handle assembly, comprising:
a handle portion;
a trigger, pivotably attached to the handle portion; and
a tubular shaft extending through the handle assembly;
a draw bar assembly retractably disposed within the handle assembly, the draw bar assembly comprising:
a draw bar tube extending through the tubular shaft, the draw bar tube having a channel disposed through the draw bar tube configured to receive the suture;
a draw bar housing disposed at a first end of the tubular shaft, the draw bar housing having a cutout configured to receive an end of the suture such that the end of the suture wraps around the cutout; and
a draw bar disposed within the draw bar tube and configured to receive the suture anchor mounted on a tip of the draw bar,
wherein upon actuating the trigger the entire draw bar assembly is retracted.
5. The suture delivery system according to claim 4 , wherein the tubular anchor body is configured such that pulling an end of the suture at the proximal end causes the tubular anchor body to become compressed.
6. The suture delivery system according to claim 4 , wherein the tubular anchor body is made entirely of suture material.
7. The suture delivery system according to claim 4 , wherein the tubular anchor body consists of suture material.
8. The suture delivery system according to claim 4 , wherein an entirety of the suture anchor is made of only suture material.
9. The suture delivery system according to claim 4 , wherein the suture forms a suture loop outside of the distal tip.
10. The suture delivery system according to claim 4 , wherein a plurality of sutures is woven from the distal tip and extending through the bore and exiting through the proximal end.
11. The suture delivery system according to claim 10 , wherein each of the plurality of sutures forms a suture loop outside of the distal tip.
12. The suture delivery system according to claim 4 , wherein the suture anchor consists of:
the tubular anchor body made of entirely of suture material; and
the suture.
