Abstract
A closure device and system for closing openings in tissue. After placing sutures in the tissue, the sutures are clamped by the closure device to hold the sutures in place and close the opening in the tissue.
Claims20
(canceled)
The closure device of claim 6, wherein the first engagement mechanism includes first threads and the second engagement mechanism includes second threads.
The closure device of claim 6, wherein the first engagement mechanism and the second engagement mechanism enable the inner body to rotate within the outer body to close the gap.
The closure device of claim 6, wherein the first opening is non-centrically located in the outer body and wherein the second opening is non-centrically located in the inner body.
The closure device of claim 6, the inner body comprises a slot on a top surface, where in the slot engages with a rotator rod to rotate the inner body.
A closure device for closing an opening, the closure device comprising:
- an outer body having a first opening, the outer body including a first engagement mechanism;
- an inner body having a second opening the inner body including a second engagement mechanism that is complementary to the first engagement mechanism, wherein the first engagement mechanism and the second engagement mechanism cooperate to close a gap between the outer body and the inner body to clamp sutures between the outer body and the inner body, wherein the outer body comprises a non-circular perimeter, the non-circular perimeter enabling the outer body to be held while the inner body rotates.
A closure system for closing an opening in tissue, the closure system comprising:
- a closure device including an inner body and an outer body, wherein the inner body and the outer body cooperate to clamp sutures used in closing the opening;
- a holder tube having a distal end and a proximal end, the closure device disposed in the distal end prior to deployment;
- and
- a rotator rod that cooperates with the inner body to clamp the sutures.
A method for closing an opening in tissue, the method comprising:
- placing sutures in walls around the opening in the tissue;
- passing the sutures through a closure device;
- and
- closing the closure device to clamp the sutures in place to substantially close the opening in the tissue.
The method of claim 22, further comprising rotating the inner body relative to the outer body to close the gap and clamp the sutures between the inner body and the outer body.
