Soft suture anchors are disclosed that can be formed into a pre-strung array with a common working suture. Each anchor includes the common working suture and a soft anchor member that is expandable when implanted. This allows first locking an individual anchor into a bone hole followed by tensioning the suture and independently locking the suture at the anchor. A first anchor is implanted through the tendon and the suture is locked. A second anchor is implanted a selected close distance from the first anchor, the working suture is tensioned between the first and second anchors, and the working suture is locked at the second anchor to create a single suture tensioned and locked stitch between the first and second anchor. This process is repeated for each anchor in the array.

Tensionable and lockable soft suture anchors and anchor arrays for anatomical attachment of soft tissue to bone

A system of toggle type suture anchors is disclosed. The plurality of suture anchors is connected in series by a single working suture and each of the suture anchors allows tensioning of the working suture between itself and the prior anchor implanted in the serial string. Further, each anchor includes a loop type locking mechanism to lock the working suture in place subsequent to tensioning. This creates an independently tensioned suture stitch between each implanted suture anchor and the just previously implanted anchor. In total the system as implanted creates a continuous array of single anchor to anchor stitches which can be placed close together in high density to form a line or region of stitches for a more robust securement of soft tissue to bone.

Knotless micro suture anchor array for high density anatomical attachment of soft tissue to bone

Methods and apparatus for creating a seam like array of suture stitches joined in series by sequential anchors in bone. The anchors are transtendon implants positioned through the tendon in the original tendon footprint and each array includes four or more anchors. The seam like array extends across at least a portion of the tendon. The stitches can extend generally perpendicular to the direction of the tendon orientation. In rotator cuff repair, the anchors are positioned in the original footprints of the infraspinatus and/or supraspinatus tendons and the seam like array extends in an anterior to posterior direction across the particular tendons torn and repaired. The entire array of anchors can be positioned in the medial half of the original footprints.

Method and apparatus for creating a seam-like anatomical low creep attachment of soft tissue to bone

Methods for creating high-density arrays of suture stiches through a tendon into bone for reattachment of a torn tendon, particularly a rotator cuff tendon. The method includes providing a pre-strung plurality of anchors, each anchor having at least one passage therethrough with a continuous length of suture slidably and serially threaded through the at least one passage of each anchor. Each of the anchors further includes a locking assembly for locking the suture within the individual anchor. A first anchor is implanted through the tendon and the suture is locked. A second anchor is implanted a selected close distance from the first anchor, then applying tension to the suture extending from the first anchor and passing through the second anchor the second anchor is locked to create a single suture tensioned and locked stitch between the first and second anchor. This process is repeated for each anchor in the array.

Method for creating a tensionable and lockable suture anchor array for anatomical attachment of tissue to bone

A system of toggle type suture anchors is disclosed. The plurality of suture anchors is connected in series by a plurality of independently cinchable working suture loops with one working suture loop connecting each pair of anchors in series to form a chain. Each of the suture anchors as connected by working suture loops allows tensioning of the working suture between itself and the prior anchor implanted in the serial string. Further, each anchor includes a loop type locking mechanism to lock the cinchable working suture loop subsequent to tensioning so that the loop remains fixed in size during cyclic loading during joint use. This creates an independently tensioned suture stitch between each implanted suture anchor and the just previously implanted anchor. In total the system as implanted creates a high density, continuous array of anchor-to-anchor stitches for robust securement of soft tissue to bone.

Individually lockable cinch loop micro suture anchor array for high density anatomical attachment of soft tissue to bone

A delivery device for transtendinous implantation of a toggle-type suture anchor into bone is disclosed. The device includes a proximal housing having an outer tubular shaft extending distally with a lumen therethrough. An anchor delivery tube extends through the lumen of the outer tubular shaft having a proximal end affixed to the proximal housing. The anchor delivery tube includes a nub portion that is used to insert through the tendon and partly into bone to maintain registration with a bone hole into which an anchor is placed. A bone punch assembly extends through the lumen of the anchor delivery tube and the nub portion with a pointed distal end. When the bone punch is fully inserted, the pointed distal end extends a distance distal of the distal end of the nub portion.

Delivery device for implanting knotless micro-suture anchors and anchor arrays for attachment of soft tissue to bone

An assembly and method are provided for incorporation into suture anchor designs to facilitate the locking of a slidable working suture after it has been tensioned. The assembly can be utilized on multiple anchors in a pre-strung chain on a single working suture to create continuous, individually tensioned suture bridges between anchors in series, without knot tying. Further, the bridges are independently locked with selected tension for the particular application. An anchor body having at least one suture receiving passage therethrough is threaded with a working suture wherein the working suture flosses through the passage when tension is applied to the working suture. A locking cord extends through a second passage through the anchor body, the locking cord having a collapsible loop extending out the second passage and encircling a portion of the working suture, wherein collapsing the loop locks the working suture after tensioning.

Locking suture construct for tensioned suture to suture stitches in anchor arrays for attaching soft tissue to bone

A method and apparatus are provided for transtendinous implantation of a toggle-type bone anchor. Measured from the top surface of the tendon, the entire bone anchor is inserted to a depth of greater than or equal to 20 mm. during a rotator cuff repair on the humeral head. The anchor is pushed by the same bone punch that formed the initial hole to assure proper depth of placement. Further, the apparatus includes a nub portion that, in use, protrudes into the bone hole formed by the bone punch and maintains registration with the bone hole when the bone punch is retracted. An angled distal end on the anchor initiates toggling during insertion into the bone and at least one proximal projecting fin prevents the anchor from backing out of the bone hole while facilitating further rotation of the anchor when a suture is pulled to complete toggling.

Methods for transtendinous implantation of knotless micro suture anchors and anchor arrays

A toggle-type suture anchor for transtendinous implantation in bone to secure soft tissue thereto during repair of a tear, especially a rotator cuff repair. The anchor can include an elongate body with side surfaces defining a maximum diameter of the body. The body can also include proximal, middle and distal bores extending from the top surface to the bottom surface, each bore located at spaced intervals along the elongate body with a single suture passing into the proximal bore top surface and out the bottom surface, then back up through the distal bore bottom surface out the top surface leaving a length of suture extending past the middle bore bottom surface. To assure toggling in transtendinous delivery into bone, the elongate body can include a pair of fins extending both proximally and radially outward from the elongate body to prevent back out once placed in a bone hole.

Knotless micro-suture anchors and anchor arrays for anatomical attachment of soft tissue to bone

A toggle-type suture anchor that incorporates individual suture tensioning and locking without knot tying. The anchor includes an elongate toggle body having a working suture pre-threaded into a first passage and back up and out a second passage with a length running longitudinally adjacent the side of the anchor. A locking suture loop is pre-threaded into a third passage between the first and second passage and includes a collapsible loop that encircles a portion of the length of suture running longitudinally adjacent the side of the anchor. With the loop open, the working suture can slide through the anchor, however, when the loop is closed the working suture is locked in position to retain tension on the working suture. The anchor can be utilized in a pre-strung connected array of anchors.

Tensionable and lockable micro suture anchors and anchor arrays for anatomical attachment of soft tissue to bone

Cartridges configured to hold anchors and associated locking sutures and a common suture used in an array of anchors. A suture anchor array is connected in series by a single working suture and each of the suture anchors allows tensioning of the working suture between itself and the prior anchor implanted in the serial string. Further, each anchor includes a suture lock having a free tail that can be pulled to lock the working suture in place subsequent to tensioning. This creates an independently tensioned suture bridge between each implanted suture anchor and the just previously implanted anchor. The cartridges are configured to securely hold an individual anchor and store the tail of the suture lock, while allowing flossing of anchors along the common suture.
