Knotless suture locking bone plate
A syndesmosis system includes a bone plate and an anchor. The bone plate includes a body extending between first and second surfaces. The body defines a strand-locking hole extending from the first surface to the second surface. A first locking element and a second locking element each extend from a first side wall of the strand-locking hole to a second side wall of the strand-locking hole. Each of the first anchor and the second anchor extend transverse to a central axis of the anchor hole. The anchor includes a body defining a first wing and a second wing. The first and second wings are coupled at a distal end and are biased away from a longitudinal axis of the body. The first and second wings are configured to maintain the anchor in a fixed position when inserted into a hole formed in a bone.
Devices, systems, and methods for repairing soft tissue and attaching soft tissue to bone
Devices, systems and/or methods for fixating soft tissue to bone are provided. In one embodiment, a repair device for fixating soft tissue to bone with a bone anchor includes a soft tissue anchor and one or more flexible members. The soft tissue anchor includes a base with multiple legs extending from the base. The one or more flexible members are coupled to the base and configured to extend from the base to the bone anchor with a fixed length. With this arrangement, the fixed length of the one or more flexible members is configured to maintain a substantially fixed pre-determined distance between the soft tissue anchor and the bone anchor such that, as the bone anchor is seated into bone, the one or more flexible members pulls the soft tissue anchor down against the soft tissue to fixate the soft tissue to the bone.
Surgical filament snare assemblies
A surgical filament snare assembly including an anchor capable of being fixated in bone and having a filament engagement feature. A first filament has a noose with first and second noose limbs connected, preferably slidably connected, to the filament engagement feature of the anchor. The first and second noose limbs emerge from the anchor as first and second free filament limbs which are capable of being passed through tissue to be repaired and then passable through the noose. The noose, such as one or more half-hitches, is capable of receiving the free filament limbs and strangulating them when tension is applied to at least one of the free filament limbs and the noose to enable incremental tensioning of the tissue after the anchor is fixated. Preferably, the snare assembly further includes a flexible sleeve joining at least some portion of the first and second free filament limbs to facilitate passing of the free filament limbs at least through the tissue as a single unit.
Suture anchor
An anchor device and system for coupling soft tissue to osseous tissue includes a stopper member that supports a loop of suture material. A fixing member includes features that allow it to be rigidly coupled to surrounding bone and thus hold the stopper member in a cavity within the bone. The loop of suture material, in turn, supports a second suture device, which is coupled to, and thus retains, the soft tissue. In certain embodiments, the fixing member includes a wadding structure having a generally elastic property.
DEVICES, SYSTEMS, AND METHODS FOR ATTACHING SOFT TISSUE TO BONE TISSUE
A suture anchoring device for fixing a soft tissue to a bone tissue is disclosed that enables the exchange of sutures between anchors after implantation. The suture anchoring device may include a body that is inserted into the bone tissue, a suture exchange fitting situation within a passage formed within the body, and one or more pre-loaded sutures looped through the suture exchange fitting and projecting proximally from a proximal opening formed in the body. Surgical kits and surgical methods for performing various repair procedures using one or more suture anchoring device are also disclosed.
Knotless implants, instruments, and methods
A suture anchor and methods of use thereof are disclosed. The suture anchor comprises an anchor body having a slot formed in the body and a passage extending through the body in a first direction. The passage is sized to permit a suture to traverse the body through the passage. The suture anchor also has a shaft with a sharp portion, and the slot and the passage intersect within the anchor body. The shaft is movable relative to the anchor body within the slot from a first position in which the sharp portion and the passage do not intersect, to a second position in which the sharp portion and the passage intersect. The shaft can penetrate a suture or multiple suture strands to fix the suture or suture strands relative to the suture anchor.
Ligament fixation system, implants, devices, and methods of use
Devices, systems, implants and methods for achieving ligament fixation are disclosed. An implant includes a head member and an anchor member coupled to the head member. The implant includes tension member that couples the head member to the anchor member. The head member and the anchor member include a cannulation that receives the tension member therein. The implant may include a coupling member positioned between and coupling the head member and the anchor member, the coupling member including a cannulation that receives the tension member therethrough. Insertion instruments for inserting an implant for ligament fixation are also disclosed. Methods of using an implant for achieving ligament fixation are also disclosed.
ORTHOPEDIC STABILIZATION DEVICE, KIT, AND METHOD
An orthopedic stabilization device is provided having a first button and a suture. The first button includes a base portion and a locking loop extending from a distal surface thereof, and a locking member slidably receiving the locking loop. At least a portion of the suture extends through the locking loop superior the locking member in the axial direction and at least a portion of the suture extends through the locking loop inferior the locking member in the axial direction such that a portion of said suture is frictionally retainable between said locking member and said locking loop when the suture is tensioned. The device may include a second button with the suture disposed between the first and second buttons such that the suture may be held in tension therebetween.
SURGICAL FILAMENT ASSEMBLIES
A suture anchor, and a surgical filament assembly using same, capable of being fixated in a hole formed in a bone of a patient. The suture anchor preferably includes an anchor body having a distal end, a proximal end, a passage extending from the proximal end toward the distal end, at least one feature disposed on the exterior of the anchor to engage bone, and a filament knot patency element disposed within the passage and defining a channel having a sufficient minimum cross-sectional area to allow movement of a portion of a surgical filament therethrough when a removable sliding knot is formed, using the surgical filament, about the filament knot patency element. The surgical filament assembly preferably includes a first filament having a sliding knot removably positioned about the knot patency element, with a shortening limb and a tightening limb each extending from the sliding knot. The sliding knot defines an adjustable capture loop having two legs extending proximally to a bight, one leg transitioning into the shortening limb and passing through the channel of the knot patency element, the shortening limb being accessible to enable a user to shorten the capture loop. The tightening limb enables the user to tighten the sliding knot against an object extending through the capture loop to secure the object to the anchor.
SLACK REDUCING SUTURE ANCHOR ASSEMBLY AND METHOD OF TISSUE REPAIR
Surgical anchor assemblies and method of tissue repair using the same. The surgical anchor assemblies have a cannulated fixation device, an implant configured to be coupled to the fixation device, and a stop mechanism for preventing relative movement between the fixation device and the implant, such that the fixation device and the implant are configured to rotate together, and a flexible strand winds up to reduce any slack in the flexible strand used for the repair.
