TENSIONABLE AND LOCKABLE 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 several exemplary designs of toggle bodies having a working suture pre-threaded through one or more passages therethrough. A locking suture loop is pre-threaded relative to the working suture 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. Alternatively, the locking suture loop can be replaced with a mechanical locking member that moves from a first unlocked to a second locked position. The exemplary anchors can be utilized in a pre-strung connected array of anchors.
METHOD AND APPARATUS FOR CREATING A SEAM-LIKE ANATOMICAL LOW CREEP 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.
INDIVIDUALLY LOCKABLE CINCH LOOP 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 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.
Pivot-based medical holding system and method
A medical holding system and method are disclosed herein. The medical holding system, in an embodiment, includes a retainer and a pivot device having a plurality of arms. Each of the arms is configured to be engaged with the retainer. The medical holding system also includes a grasper configured to be coupled to the pivot device. The grasper is configured to grasp a portion of an implantable element, and the pivot device is configured to be pivoted relative to the retainer.
IMPLANT HAVING FILAMENT LIMBS OF AN ADJUSTABLE LOOP DISPOSED IN A SHUTTLE SUTURE
A device having an implantable body associated with at least two filaments or sutures and configured for use in soft tissue reconstructions is provided. One exemplary embodiment includes an implantable body, an adjustable filament loop for holding ligament grafts that is coupled to the body, and a shuttle suture removably coupled to the implantable body and configured for shuttling the body through at least a portion of a bone tunnel. The loop can be defined by a self-locking knot, and one or more loop-adjusting limbs can extend from the knot, with a portion of the limb(s) also extending into a hollow portion of the shuttle suture. In some embodiments having two adjustable limbs, an intermediate portion of each limb can be the portions disposed in respective hollow portions of the shuttle suture. Other configurations of devices and systems, as well as methods for performing ACL repairs, are also provided.
TENDON REPAIR SYSTEM
A system for coupling a tendon to a bone may include a tendon coupling device engageable with a tendon, a fastener to secure the tendon coupling device to the tendon, a bone coupling device, and a flexible element. The flexible element may include a first portion and a second portion. The first portion of the flexible element may be couplable with the fastener to securably attach the flexible element to the tendon. The bone coupling device may include a bone-facing surface engageable with a surface of the bone proximate a bone tunnel formed through the bone, and a hole formed through the bone coupling device. The second portion of the flexible element may be receivable through the bone tunnel and the hole formed through the bone coupling device to engage an opposing surface of the bone coupling device and securably couple the tendon to the bone.
HOLLOW TWO-SECTION IMPLANTATION KNOTLESS SUTURE ANCHOR
The present invention pertains to a hollow two-section implantation knotless suture anchor which comprises a main body, a tightening element and a taper. The main body comprises a front part, a rear part, a middle part, a first penetration part, a first accommodation space, a first thread, a tapered structure, and a perforation. The tightening element comprises a second penetration part and a second accommodation space. The taper comprises a taper body and a taper head. Moreover, the suture can pass through the perforation on the outside of the main body through the perforation. Afterthat it can pass through the first accommodation space and then the second accommodation space on the outside of the tightening element from the side of the tightening element opposite to the main body. Finally, it can extend on the outside of the main body. Hence, by pulling the ends of the suture, the tightness of the suture tightened by the tightening element and the front part is adjustable. Also, when the taper body of the first penetration and the second penetration is positioned, the taper head is next to the tightening element. Thus, by rotating the taper, both the main body and the tightening element are rotatable.
Tensionable knotless anchors and methods of tissue repair
Surgical devices and methods of tissue repair using tensionable knotless fixation devices. A flexible material (for example, suture or suture tape) may be attached to the fixation device. A flexible material may be threaded through an eyelet of a tip provided as part of a swivel anchor assembly to provide added stability to the fixation devices.
Point-loading knotless fixation devices
Surgical constructs and methods for soft tissue to bone repairs, without knot tying. The soft tissue repair constructs include a fixation device, a flexible strand, and a shuttle/pull device attached to the flexible strand and provided within the body of the fixation device. A splice is formed by pulling on the shuttle/pull device to allow desired tensioning of soft tissue to be fixated or repaired relative to the bone.
Surgical construct with adjustable loops and sliding knot
This disclosure relates to methods of surgical tissue reconstruction, such as for joint or ligament repair, and associated surgical constructs.
