Abstract
The present invention involves an automatic suture locking device useable with vascular closure device. The suture locking device includes a housing and a locking mechanism. The locking mechanism has locked and unlocked positions. In the locked position, a suture pathway through the mechanism is sufficiently tortuous to prevent free suture movement.
Claims14
A vascular closure assembly, comprising:
- an anchor;
- a collagen;
- a suture coupled to the anchor and extending through the collagen;
- a suture locking mechanism comprising a housing and at least first and second locking posts extending cantilevered from the housing;
- the suture locking mechanism being rotatable between a non-locked position and a locked position;
- wherein the suture is capable of movement when the suture locking mechanism is in the non-locked position and the suture at least partially wraps around the first and second locking posts and is relatively incapable of movement when the suture locking mechanism is in the locked position;
- wherein rotating movement of the suture locking mechanism is configured to occur upon deployment of the anchor and the collagen.
4 more elements
A vascular closure device, comprising:
- an anchor;
- a collagen;
- a locking device;
- and
- a suture coupled to the anchor and extending through the collagen and the locking device, wherein the locking device comprises:
- a housing;
- and
- at least two cantilevered locking posts extending from the housing;
- wherein the locking device being rotatable between a first orientation and a second orientation, the first orientation providing the suture with a relatively non-tortuous path defined for the suture through the locking device, and
- the second orientation providing the suture with a relatively tortuous path defined at least in part between the at least two locking posts;
- wherein rotating movement of the locking device is configured occur upon deployment of the anchor and the collagen.
8 more elements
A vascular closure device, comprising:
- an anchor;
- a collagen;
- a suture;
- and
- a suture locking assembly, the suture locking assembly including a housing and at least two cantilevered locking posts extending from the housing;
- wherein the suture is coupled to the anchor and extends through the collagen and the suture locking assembly in a space defined at least in part between the at least two locking posts, the suture locking assembly being rotatable between unlocked and locked positions;
- wherein rotating movement of the suture locking assembly is configured occur upon deployment of the anchor and the collagen.
4 more elements
A vascular closure assembly, comprising:
- an anchor;
- a collagen;
- a suture coupled to the anchor and extending through the collagen;
- a locking element comprising a housing and at least first and second cantilevered locking posts extending from the housing;
- the locking element being rotatable between a first orientation and a second orientation;
- in the first orientation, the locking element provides a non-tortuous pathway for the suture that is defined at least in part between the first and second locking posts such that the suture can move relative to the housing;
- and
- in the second orientation, the locking element provides a tortuous pathway for the suture that is defined at least in part between the first and second locking posts such that the suture is relatively immobile relative to the housing;
- wherein rotating movement of the locking element is configured to occur upon deployment of the anchor and the collagen.
