Abstract
A tissue aperture closure device may include more than one suture deployed in multiple directions around a perimeter of a tissue aperture. The sutures may be pulled through a suture lock to tension the sutures and close the tissue aperture. The suture lock may be transitioned between a locked configuration and an unlocked configuration in which the tension of the sutures may be adjusted.
Claims34
A tissue aperture closure device comprising:
- a suture lock;
- a plurality of sutures extending through the suture lock, wherein a first portion of each suture of the plurality of sutures is configured to be attached to tissue, and wherein the suture lock is configured to maintain a length of the plurality of sutures extending out from the suture lock in a first locked configuration and to allow the plurality of sutures to be pulled through the suture lock to change the length of the plurality of sutures extending out from the suture lock in a second unlocked configuration, and wherein the suture lock is configured to reversibly move between the first locked configuration and the second unlocked configuration;
- a plurality of openings positioned around a perimeter of the suture lock configured to secure the plurality of sutures to the tissue aperture closure device;
- and
- a channel configured to receive the plurality of sutures, and wherein the suture lock is configured to engage the plurality of sutures in the channel to lock the sutures in the locked configuration.
2 more elements
A tissue aperture closure device comprising:
- a suture lock;
- a plurality of sutures, wherein each suture of the plurality of sutures includes a first portion attached to the lock and a second portion that passes through an opening formed in the lock, wherein pulling on the second portion of the suture pulls the second portion of the suture through the lock;
- a plurality of openings positioned around a perimeter of the suture lock configured to secure the plurality of sutures to the tissue aperture closure device;
- and
- a channel configured to receive the plurality of sutures, and wherein the suture lock is configured to engage the plurality of sutures in the channel to lock the sutures in the locked configuration.
2 more elements
A method of closing an aperture formed in tissue, the method comprising:
- deploying a plurality of sutures around a perimeter of an aperture formed in tissue;
- pulling the plurality of sutures through a suture lock to shorten a length of the plurality of sutures, wherein shortening a length of the sutures closes the aperture, wherein the suture lock includes a channel configured to receive the plurality of sutures and a plurality of openings positioned around a perimeter of the suture lock to secure the plurality of sutures;
- and
- locking a length of the plurality of sutures by engaging the plurality of sutures in the channel with the suture lock to maintain the shortened length of the sutures.
1 more element
A tissue aperture closure device comprising:
- a suture lock;
- a plurality of sutures extending through the suture lock, wherein a first portion of each suture of the plurality of sutures is configured to be attached to tissue, and wherein the suture lock is configured to maintain a length of the plurality of sutures extending out from the suture lock in a first locked configuration and to allow the plurality of sutures to be pulled through the suture lock to change the length of the plurality of sutures extending out from the suture lock in a second unlocked configuration;
- and
- a tether, wherein the plurality of sutures are connected to the tether, and wherein pulling the tether pulls the plurality of sutures simultaneously.
1 more element
A method of closing an aperture formed in tissue, the method comprising:
- deploying a plurality of sutures around a perimeter of an aperture formed in tissue;
- pulling the plurality of sutures through a suture lock to shorten a length of the plurality of sutures, wherein shortening a length of the sutures closes the aperture;
- and
- locking a length of the plurality of sutures with the suture lock to maintain the shortened length of the sutures, wherein the plurality of sutures are connected to a tether, and wherein pulling the plurality of sutures includes pulling the tether to pull the plurality of sutures simultaneously.
