An anchor (10) for implantation in body tissue (12) to hold a line (14) comprises: an elastic material formed to have an unfolded configuration for placement within the body tissue (12), and a folded configuration for use prior to deployment of the anchor (10) and arranged to permit placement of the anchor (10) into an anchor tube (38) prior to deployment. The anchor (10) is arranged to be elastically deformed into the folded configuration by application of a constraining force, and will return to the unfolded configuration when no constraining force is applied. When the anchor (10) is in the unfolded configuration the anchor (10) has an elongate configuration comprising two anchor pins (82) extending in opposite directions with one either side of a centre (80) of the anchor (10), whilst when the anchor (10) is in the folded configuration the two pins (82) both extend in the same direction; and wherein ends (84) of the pins (82) are arranged to pierce the body tissue.

The implantable textile anchor includes a collapsible member including a first end, a second end and a plurality of eyelets arranged between the first end and the second end, and at least one filament. The collapsible member is braided to form bifurcating and converging portions, which define the eyelets. The at least one filament is guided through eyelets of the collapsible member so that by pulling on the at least one filament the collapsible member collapses to a form with an increased lateral extension. The at least one filament is knotted to an eyelet and/or the at least one filament and at least a second filament are made integral with the collapsible member.

In one embodiment, the present invention includes a method for securing tissue to bone, including drilling a bone hole into the bone; passing a filament through the tissue, the filament including a first end, a second end and a length therebetween, the second end having a loop; passing the first end of the filament through the loop of the filament; pulling on the first end of the filament such that the loop travels along the length of the filament and to the tissue; passing an anchor along the length of the filament, from the first end towards the loop and tissue; engaging the loop with a distal end of the anchor; positioning the distal end of the anchor, with the loop of the filament, into the bone hole; and securing the anchor in the bone.

A heart valve annulus repair device having a tissue engaging member and a plurality of anchors. The tissue engaging member includes a loop of wire. Each of the anchors has a pointy front end and a back end and a slot that runs in a front-to-back direction. The anchors are distributed about the loop of wire with the front ends of the plurality of anchors facing the heart valve annulus and with the loop of wire passing through the slots. The device further includes means for implanting the anchors into the heart valve annulus tissue so that the tissue engaging member becomes affixed to the heart valve annulus.

Various devices, systems, and methods are provided for securing soft tissue to bone. In one exemplary embodiment, a two-piece inserter tool is provided that includes a tip portion that is configured to be removably coupled to a handle portion. A distal portion of the tip portion can be configured to be coupled to a suture anchor, and the tip portion and the anchor can be passed through a continuous suture loop prior to mating the tip portion to the handle portion.

Disclosed herein are methods and devices for securing soft tissue to a rigid material such as bone. A tissue anchoring device is described that comprises an anchor body and a spreader such that tissue may be captured or compressed between outside surfaces on the anchor and inside surfaces of a bone tunnel to secure the tissue within the tunnel. Methods are described that enable use of the bone anchoring device to secure a tissue graft into the tibial and femoral bones during anterior cruciate ligament (“ACL”) reconstruction.

A suture anchor may include an anchor body having an exterior surface, a proximal end, a distal end, a longitudinal axis extending between the proximal and distal end, an interior longitudinal passageway extending at least partway from the proximal end toward the distal end, a proximal opening communicating with the longitudinal passageway nearer the proximal end, and a plurality of distal openings communicating with the longitudinal passageway nearer the distal end. The suture anchor may also include a suture routed through the plurality of distal openings, with a first portion extending within the longitudinal passageway between the proximal opening and the distal opening, a second portion, contiguous to the first portion, extending out of the anchor body, a third portion, contiguous to the second portion, extending within the longitudinal passageway proximally to distally, and a fourth portion, contiguous to the third portion, extending along the exterior surface distally to proximally.

A tissue anchor assembly comprises a tissue anchor; a suture; and an adjustment button coupled with the suture. The adjustment button is adapted to adjust tension relative in the suture. When tension is applied to a second suture section trailing away from the tissue anchor, the adjustment button is engaged with the second suture section through locking splines and the adjustment button slides along a portion of the suture to increase a distance between the adjustment button and the tissue anchor. When tension is applied to a first suture section trailing away from the tissue anchor, the adjustment button moves in a direction towards the tissue anchor to reduce a distance between the adjustment button and the tissue anchor.

A method includes forming a bone tunnel through a first bone and a second bone and inserting a flexible construct through the bone tunnel. The flexible construct includes a first anchoring element and a second anchoring element coupled by at least one flexible strand defining an adjustable loop. The at least one flexible strand includes a first end extending from the first anchoring element in an opposite direction from the adjustable loop. A length of the adjustable loop is adjusted to position the first bone and the second bone in a selected spacing. The first end of the at least one flexible strand is coupled to a tissue section using a third anchoring element.

Methods and systems are provided for securing tissue to bone. A surgical system can include an outer shaft, an elongate inner shaft, and an implantable suture anchor assembly including first and second anchor bodies. The second, more proximal, anchor body has one or more openings extending through a side wall or through opposed side walls thereof. The inner shaft is configured to be received within the outer shaft and through the first and second anchor bodies such that a distal end of the inner shaft protrudes beyond a distal end of the first anchor body. The inner shaft is configured to be removably coupled to the first anchor body such that the inner shaft is configured to be rotated to cause a proximal portion of the first anchor body to move proximally into a lumen extending through the second anchor body and to occlude the opening in the second anchor body.
