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.
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.
