Abstract
Disclosed are systems, methods, and devices for closing an opening. The methods, systems, and devices include a looped body. The looped body includes a first looped portion having a first apex and a second apex separated by a first distance while the looped body is in a pre-deployed state. The first looped portion is configured to resiliently move to a deployed state in which the first apex and the second apex are separated by a second distance, the first distance being greater than the second distance.
Claims19
A suture-fastening device, comprising:
- a looped body, the looped body having a first looped portion having a first apex and a second apex separated by a first distance while the looped body is in a pre-deployed state and being configured to resiliently move to a deployed state in which the first apex and the second apex are separated by a second distance, the first distance being greater than the second distance.
4 The device of claim 1, wherein the looped body further forms a second looped portion while in the pre-deployed state, the second looped portion and the first looped portion being operatively coupled such that the first looped portion moves to the deployed state by expansion of the second looped portion.
The device of claim 4, wherein the second looped portion includes a third apex, the third apex and the second apex being separated by a third distance in the pre-deployed state and a fourth distance in the deployed state, the fourth distance being larger than the third distance.
A system for maintaining apposition in a suture, the system comprising:
- a deployment device, the deployment device having a housing and an actuator assembly;
- and
- a suture-fastening device, the suture-fastening device having a looped body, the looped body having a first looped portion having a first apex and a second apex separated by a first distance while the suture maintaining device in a pre-deployed state and being configured to resiliently move to a deployed state in which the first apex and the second apex are separated by a second distance, the first distance being greater than the second distance, wherein the deployment device is configured to move the suture-fastening device from the pre-deployed position to the deployed position.
A method of securing a suture in tissue, the method comprising:
- placing a suture-fastening device in a pre-deployed state, the suture-fastening device having a looped body, the looped body having a first looped portion having first and a second apex separated by a first distance while the suture-fastening device is in the pre-deployed state and being configured to resiliently move to a deployed state in which the first apex and the second apex are separated by a second distance, the first distance being greater than the second distance;
- threading ends of the suture through the suture-fastening device;
- and
- moving the suture-fastening device to the deployed state.
