This disclosure relates to surgical fixation systems and methods. The surgical fixation systems may include one or more loops and one or more reinforcement materials. The surgical fixation systems can be used in various knotless tissue repair procedures.

Suture constructs and methods are provided for securing soft tissue to bone. One exemplary embodiment of a construct includes a first limb, a second limb, a coaxial region, and a collapsible snare defined by the first and second limbs. The coaxial region can be formed by a portion of the second limb being disposed in a volume of the first limb, which allows for a low profile construct that is useful in various soft tissue repair procedures. The construct can be configured to be disposed in tissue to draw the tissue toward bone, and the coaxial region can be deconstructed so that the first and second limbs can be used to help secure the desired location of the tissue with respect to the bone. Various features of the construct and methods for using the same in a surgical procedure are also provided.

Knotless surgical constructs and methods of tissue repairs. A surgical construct can offer both repair and shuttling capabilities to allow for a single pass to load multiple sutures at once. A surgical construct can pass or shuttle multiple repair sutures while making a single pass through or around soft tissue.

Systems, devices, and methods are provided for securing soft tissue to bone. One exemplary embodiment of a surgical soft tissue repair device includes a snare assembly coupled to a soft anchor in which the soft anchor has a first, unstressed configuration that can be used to insert the anchor into bone and a second, anchoring configuration that can be used to fixate the anchor in the bone. The snare assembly can be configured to actuate the anchor from the first configuration to the second configuration, and it can also be used to engage and approximate tissue by drawing the tissue closer to the anchor fixated in the bone. The snare assembly can be used in conjunction with a number of different anchor configurations, and other exemplary systems, devices, and methods for use with soft tissue repair are also provided.

A cord comprises a braided sheath of strands having an outer surface, an inner surface, and a central hollow portion defined by the inner surface and having a volume and a core within the central hollow portion of the tubular braided sheath, such that when the cord is in a relaxed state the tubular braided sheath has a cylindrical shape and a relaxed volume of the central hollow portion wherein the core does not fill the relaxed volume of the central hollow portion of the tubular braided sheath; when the cord is in a longitudinal tensioned state, the tubular braided sheath elongates under the longitudinal tension such that a tensioned volume of at least a part of the central hollow portion of the tubular braided sheath is less than the relaxed volume; and the inner surface of the tubular braided sheath of tensioned volume contacts and cinches a surface of the core.

This disclosure relates to surgical fixation systems and methods. The surgical fixation systems of this disclosure may include various combinations of fixation devices, soft suture constructs, and/or adjustable loops and are configured for use in various knotless surgical methods, including but not limited to, syndesmosis, AC joint, UCL, bunion, anterior cruciate ligament (ACL), and posterior cruciate ligament (PCL) surgical methods.

Provided by the present invention is a loop, comprising a fixing plate and a suture, wherein the fixing plate is provided with at least two threading holes, the suture is wound to form a first coil and a second coil, the first coil and the second coil are arranged on a same side of the fixing plate, and two ends of each of the first coil and the second coil are configured to pass through the threading holes; the two ends of the first coil are movably connected to form a first adjustable portion, a third end of the second coil is continuously connected to a first end of the first coil to form a fixing portion, the fixing portion is configured to compress a fourth end of the second coil to form a second adjustable portion. By providing the first adjustable portion and the elastic portion, not only the purpose of automatically adjusting the length of the coil in the loop is achieved, but also the coil in the loop cannot be enlarged and retreated due to the pulling force of a graft when no artificial external force exists, the operation time is shortened, and the operation risk is reduced. A manufacturing method of the loop is further provided by the present invention.

An orthopedic attachment system includes a first bone anchor, a second bone anchor, and a flexible connector. The flexible connector is connected between the first bone anchor and the second bone anchor. The flexible connector includes a sliding loop, a tensioning end and a fixed end. The sliding loop is connected to a sling loop bone anchor, and the fixed end is connected to the fixed end bone anchor. The tensioning end is slidably connected and lockable to the fixed end. A flexible connector, a method for attaching a flexible connector between at least two bone anchors in a patient's body, and a method of making a flexible connector are also disclosed.

Tensionable, knotless, self-locking surgical constructs and methods for surgical repairs are disclosed. A tensionable, knotless, self-locking surgical construct includes a flexible coupler (repair suture) and a plurality of shuttle/pull devices loaded onto a fixation device. The fixation device can be a knotless fixation device such as a knotless soft anchor, for example, an all-suture knotless anchor. The knotless surgical construct provides multiple passes of the flexible coupler itself (repair suture itself), to achieve the desired friction and to also create a reverse purchase resistance to loosening. The flexible coupler (repair suture) is passed around tissue two or more times (and subsequently through the cannulation of the anchor sheath two or more times) creating a stuffed friction effect. There is no cinching loop in the final repair.

A tissue fixation apparatus can include a flexible construct and an elongated locking member. The flexible construct can include at least two adjustable loops and tensioning members. The two adjustable loops can be configured to pass through the first tissue, and to be spaced apart along an outer surface of the first tissue in a first direction. The tensioning members can extend from the two adjustable loops, and can be configured to reduce the two adjustable loops from a first size to a second size. The flexible construct can be attached to the second tissue by an anchor. The locking member can be configured to be received within the two adjustable loops at the first size, and to engage the two adjustable loops at the second size.
