Externally magnetically operated suture anchor
Provided herein are compositions and methods including a magnetically actuated suture anchor including an anchor magnet configured to be magnetically moved using an external magnet from a first position to a second position, wherein in the first position, a tension is maintained in a suture connected to the magnetically actuated suture anchor and in the second position the tension in the suture is released.
1 . A magnetically actuated suture anchor comprising:
an anchor magnet configured to be magnetically moved using an external magnet from a first position to a second position, wherein the anchor magnet is magnetically pulled using the external magnet, and wherein in the first position a tension is maintained in a suture connected to the magnetically actuated suture anchor and in the second position the tension in the suture is released;
a suture winder; and
a plunger connecting the anchor magnet to the suture winder, wherein the plunger is configured and disposed to be slidably inserted into and engaged with the suture winder when the anchor magnet is in the first position and the magnetically actuated suture anchor is in a tensioned state and configured and disposed to be slidably removed from the suture winder when the anchor magnet is moved to the second position and the magnetically actuated suture anchor is in a released state.
2 . The magnetically actuated suture anchor of claim 1 , wherein the anchor magnet is magnetically pushed using the external magnet.
3 . The magnetically actuated suture anchor of claim 1 , wherein the anchor magnet comprises neodymium.
4 . A magnetically actuated suture anchor kit comprising:
a magnetically actuated suture anchor comprising:
an anchor magnet configured to be magnetically moved using an external magnet from a first position to a second position, wherein the anchor magnet is magnetically pulled using the external magnet, and wherein in the first position a tension is maintained in a suture connected to the magnetically actuated suture anchor and in the second position the tension in the suture is released;
a suture winder; and
a plunger connecting the anchor magnet to the suture winder, wherein the plunger is configured and disposed to be slidably inserted into and engaged with the suture winder when the anchor magnet is in the first position and the magnetically actuated suture anchor is in a tensioned state and configured and disposed to be slidably removed from the suture winder when the anchor magnet is moved the second position and the magnetically actuated suture anchor is in a released state; and
one or more tools to manipulate the magnetically actuated suture anchor.
5 . The magnetically actuated suture anchor kit of claim 4 , wherein the anchor magnet is magnetically pushed using the external magnet.
6 . The magnetically actuated suture anchor kit of claim 4 , wherein the anchor magnet comprises neodymium.
7 . A method of releasing tension in a magnetically actuated suture anchor, the method comprising:
providing a magnetically actuated suture anchor comprising:
an anchor magnet configured to be magnetically moved using an external magnet from a first position to a second position, wherein in the first position, a tension is maintained in a suture connected to the magnetically actuated suture anchor and in the second position the tension in the suture is released;
a suture winder; and
a plunger connecting the anchor magnet to the suture winder; and
magnetically moving the anchor magnet from the first position to the second position, wherein the anchor magnet is magnetically pulled using the external magnet;
wherein the plunger is configured and disposed to be slidably inserted into and engaged with the suture winder when the anchor magnet is in the first position and the magnetically actuated suture anchor is in a tensioned state and configured and disposed to be slidably removed from the suture winder when the anchor magnet is moved to the second position and the magnetically actuated suture anchor is in a released state.
8 . The method of claim 7 , wherein the anchor magnet is magnetically pushed using the external magnet.
