  • Publication number: 20260096813
    Abstract: A knotless valve suture assembly includes a first predefined suture loop, a first suture end coupled with the first predefined suture loop, a second predefined suture loop, and a second suture end coupled with the second predefined suture loop. At least one implant clip is included. At least one of the first and second predefined suture loops is configured to be tensioned over the at least one implant clip in response to the tensioning force applied to at least one of the first and second suture ends, respectively, to press the at least one implant clip against a replacement valve and the replacement valve against tissue.

  • Publication number: 20250281173
    Abstract: A knotless suture assembly may include a repair suture which may have a first and a second end. The first end may be coupled to a first needle. The knotless suture assembly may also include a shuttle suture. The shuttle suture may have a first end coupled to the first needle and a second end coupled to a second needle. The shuttle suture may include a shuttling feature, and the first end of the repair suture may be configured to engage the shuttling feature during a shuttling process. The knotless suture assembly may include a locking feature. The repair suture may be configured to engage the locking feature during the shuttling process. The locking feature may be configured to retain the repair suture under tension in response to the shuttling process.

  • Publication number: 20240090888
    Abstract: Surgical constructs, assemblies, and methods for tissue repairs are disclosed. A surgical construct can include a fixation device with a sliding flexible coupler and a covering for the flexible coupler. The covering includes a hollow portion adjacent a tail portion. Limbs of the flexible coupler are secured within the hollow portion. The tail portion of the covering is passed through tissue such that the hollow portion along with the limbs of the sliding flexible coupler are passed through the tissue simultaneously.

  • Publication number: 20230248354
    Abstract: 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.

  • Patent number: 11684356
    Abstract: 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.

  • Patent number: 10898179
    Abstract: Systems and methods for soft tissue to bone repairs, without knot tying. The soft tissue repair systems include self-cinching constructs with splices, loops and inserts that are pre-loaded onto knotless anchors to position the self-locking, adjustable construct at the repair site. The splice incorporates an insert in the form of a flexible strand with at least one barb, or simply in the form of a cut length of suture or braid that is inserted into the center of the cinching loop to create a thicker portion. When the cinching loop is tightened, the insert prevents loosening of the loop, locking in the cinching loop and preventing movement of the loop.

  • Patent number: 10820897
    Abstract: Surgical devices and methods of surgical repairs using the devices are disclosed. The device and methods aid in surgical repairs by allowing for quick and reproducible repairs to be made. A tensionable knotless fixation device is provided with a tensioning construct (formed of a tensioning strand, a tensionable, adjustable, knotless, self-cinching loop, and a splice adjacent the loop) pre-loaded onto a fixation device. A flexible material (for example, suture or suture tape) may be attached to a fixation device. A flexible material may be threaded through an eyelet of a fixation device.
