Meniscal repair devices, systems, and methods

Meniscal repair devices, systems, and methods are provided.

Suture anchor construct

Disclosure herein are knotless suture anchor constructs and methods of use thereof. The suture anchor constructs can include a bone anchor and a suture. The bone anchor can include a suture anchoring member and can define a cavity and a longitudinal passage extending from a trailing end of the bone anchor at least partially therethrough to the cavity. The suture anchoring member can be located in the cavity. The suture can be coupled to the suture anchoring member and can include a tensioning portion, a repair portion, and an intermediate portion. The intermediate portion can form a suture loop extending along the longitudinal passage.

SUTURE ANCHOR FOR KNOTLESS FIXATION OF TISSUE

A suture anchor for knotless fixation of tissue. The suture anchor includes an implant configured to hold a suture to be anchored in bone without requiring suture knots. The suture is secured in bone by inserting the implant holding the suture into a hole in the bone, and advancing a fixation device, such as a cannulated interference screw, over a shaft at the proximal end of the implant.

LOCKING SUTURE CONSTRUCT FOR TENSIONED SUTURE TO SUTURE STITCHES IN ANCHOR ARRAYS FOR ATTACHING 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.

METHODS FOR TRANSTENDINOUS IMPLANTATION OF KNOTLESS MICRO SUTURE ANCHORS AND ANCHOR ARRAYS

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.

METHOD FOR CREATING A TENSIONABLE AND LOCKABLE SUTURE ANCHOR ARRAY FOR ANATOMICAL ATTACHMENT OF 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.

KNOTLESS MICRO SUTURE ANCHOR ARRAY FOR HIGH DENSITY 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.

CARTRIDGE DEVICE FOR SUTURE ANCHOR AND SUTURE MANAGEMENT DURING IMPLANTATION OF A MICRO SUTURE ANCHOR ARRAY

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.

DELIVERY DEVICE FOR IMPLANTING KNOTLESS MICRO-SUTURE ANCHORS AND ANCHOR ARRAYS FOR 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.

TISSUE REPAIR

An apparatus includes a flexible fixation member having a body with a longitudinal extent and a width, the body defining a plurality of openings through the body, each of the plurality of openings formed substantially cross wise through the width of the body, and a suture having two terminal ends, the suture being interwoven through each of the plurality of openings in the body of the fixation member such that multiple portions of the fixation member are slidably coupled to the suture and configurable to form a cluster within a surgical site.
