As another example, reducing the mass of the anchor 4200 aids in increasing the velocity of the driving of the anchor 4200 into tissue. In remote anchoring, the tissue receiving the anchors is not held or secured during deployment of the anchors. As noted above, in order to accurately penetrate soft tissue that is not being held or secured, rapid penetration may be required. Lowering the mass of the anchor 4200 increases the achieved driving velocity. In an exemplary embodiment, the velocity of the driven anchors may be described according to the below equation, where m is the mass of the anchor, kspring is the spring constant of the driving spring, Ffriction is the coefficient of friction between the anchor and the distal end of the driver, and 12−11 indicates the difference in the length of the spring.
v = ( l 2 - l 1 ) ⁢ ( k spring ⁡ ( l 2 - l 1 ) - 2 ⁢ ⁢ F friction ) m
a plurality of anchors, each including a flexible stem extending proximally from a distal end, the distal end tapers to a distal tip configured to pierce tissue;
at least one inelastic closure element coupled to the anchors, wherein the closure element includes a knot;
a driver configured to drive the anchors, with the closure element coupled to the anchors, into the tissue; and
a tensioner configured to tension the closure element sufficient to (i) urge the anchors toward each other to close at least one of an aperture and a distance in the tissue located between the anchors driven into the tissue and (ii) resist opposing forces exerted on the anchors that urge the anchors apart, wherein, as the closure element is drawn proximally through the tensioner, the tensioner moves distally into approximation with the knot,
wherein a proximal end of the tensioner is removable from a body of the tensioner, wherein the closure element is coupled to the removable proximal end of the tensioner such that when the proximal end of the tensioner is removed from the body of the tensioner, the proximal end is a grip to at least one of pull and draw on the closure element.
4. The device of claim 1, wherein the anchors each include at least one barb extending proximally and radially outwardly from the distal end to a free end, the at least one barb including a radially exterior surface and a radially interior surface;
wherein the flexible stem is flexible with respect to the at least one barb and the distal tip.
5. The device of claim 1, wherein the closure element is a suture.
6. The device of claim 5, wherein the anchors each include an eyelet configured to receive the suture.
7. The device of claim 6, wherein a first end of the closure element is tied in the knot prior to the closure element being received through the eyelets.
8. The device of claim 7, wherein the tensioner includes a hollow axial interior core such that the closure element runs through the tensioner via the interior core such that the knot is larger than a distal opening of the interior core.
9. The device of claim 7, wherein a second end of the closure element is tied through the knot after the closure element is received through the eyelets.
10. The device of claim 1, wherein the anchors are disposed along a ring-shaped circumference in a first configuration.
11. The device of claim 1, wherein the driver is configured to simultaneously drive the plurality of anchors.
12. The device of claim 11, wherein the driver comprises a spring-loaded element configured to impact and impart a distally directed momentum to the anchors.
13. The device of claim 12, further comprising a trigger configured to release the spring-loaded element from a preloaded position in order to drive the plurality of anchors.
14. The device of claim 12, further comprising a handle, the trigger being disposed in handle.
15. The device of claim 1, wherein the plurality of anchors and the closure element are formed of bioabsorbable materials.
16. The device of claim 1, wherein the tensioner includes a hollow axial interior core such that the closure element runs through the tensioner via the interior core.
17. The device of claim 1, wherein the closure element extends beyond the proximal end of the tensioner.
18. The device of claim 1, wherein the anchors are disposed in a rectangular shape in a configuration.
a tensioner including a hollow axial interior core such that the closure element runs through the tensioner via the interior core;
wherein, as the closure element is drawn proximally through the tensioner, the tensioner moves distally into approximation with the knot and exerts a tension sufficient to urge the anchors toward each other in a cinching action to bring the anchors into a closed position to close at least one of an aperture and a distance in the tissue located between the anchors driven into the tissue, to secure, by the knot, the closed position of the anchors and to resist opposing forces exerted on the anchors that urge the anchors apart,
