Internal joint bracing system and suture anchoring assembly therefore
An internal bracing system is disclosed for stabilizing a joint such as the knee, shoulder, ankle or the like. The internal bracing system includes an extra-articular tension band mechanism and an anchor assembly therefore. The internal bracing system adds substantial control to unstable joints which is effective in limiting the pathological joint motions and internal slippage. The anchor anchoring assembly designed to affix a tethering device to various bony structures which form a joint, for the purpose of providing stability. The anchor assembly includes an anchor and a set screw. A series of disc structures compressed by the set screw securely holds the tether without binding.
TWO-PART ANCHOR WITH ANCHOR INSERTER
Disclosed herein are embodiments of a no-hole-preparation suture anchor including a tubular anchor body, a tapered tip coupled to the anchor body, an eyelet extending transversely through the anchor, and a plurality of longitudinal ribs extending along at least a portion of the anchor length. The material of the tapered tip is harder than that of the anchor body to facilitate insertion. An anchor inserter for use in combination with the suture anchor includes an elongated, tubular shaft defining a cannulation extending between a proximal end and a distal end. A plurality of tines extends distally from the distal end of the shaft. The anchor includes a plurality of longitudinally extending slots, dimensioned to receive respective ones of the inserter tines. The slots extend along the length of the anchor body and continue into the proximal end of the tubular shaft of the distal tip. The circumferential position of each of the slots is further selected such that the slots are circumferentially adjacent to, but do not intersect, the eyelet.
ADJUSTABLE KNOTLESS LOOPS
Methods of attaching a soft tissue to an adjacent bone at a defect site are provided. An adjustable loop region of a flexible construct contained in a bore defined by a fastener is passed through a tissue. The adjustable loop is passed through the tissue. The fastener is passed back through the adjustable loop to fold the adjustable loop upon itself. The fastener is attached to the bone. An adjusting arm on the flexible construct is engaged to reduce the size of the adjustable loop and secure the soft tissue to the bone.
Method and apparatus for coupling soft tissue to bone
A method and apparatus for coupling a soft tissue implant into a locking cavity formed within a bone. The method includes the following: implanting in bone a first anchor including a first suture construct connected to the first anchor; passing a first adjustable loop of the first suture construct at least one of over or through the soft tissue; coupling the first adjustable loop to one of a first locking feature of the first anchor or a second locking feature of a second anchor; adjusting the first adjustable loop by pulling a first end of the first suture construct; and securing the soft tissue against bone by pulling the first end of the first suture construct.
Method and apparatus for coupling soft tissue to a bone
A method and apparatus for coupling a soft tissue implant into a locking cavity formed within a bone is disclosed. The apparatus includes a member to pull the soft tissue implant into a femoral tunnel. The member includes a suture having first and second ends which are passed through first and second openings associated with the longitudinal passage to form a pair of loops. A collapsible tube is positioned about the suture. Application of tension onto the suture construction causes retraction of the soft tissue implant into the femoral tunnel and the collapse of the tube to form an anchor.
Percutaneous Valve Implants
An apparatus for implantation at an annulus (75) of an intracardiac valve includes an annuloplasty ring (110) comprising a plurality of rotatably adjoining segments (112). The ring is configured to pass over multiple threads (58), respective distal ends of which are distributed over the annulus, and, while passing over the threads, expand from a collapsed state to an expanded state by virtue of the segments rotating with respect to each other. The apparatus further comprises a lock (114), configured to lock the ring in the expanded state at the valve by inhibiting rotation of the segments with respect to each another. Other embodiments are also described.
KNOTLESS SUTURE OR TISSUE ANCHOR
Embodiments of the invention include methods and devices for securing a suture, graft, or other material to tissue with an anchor. The anchor of some embodiments includes an eyelet through which the suture, graft, or other material may be passed and mechanisms for selectively engaging the suture, graft, or other material through the eyelet. The mechanisms of some embodiments may also reinforce the anchor to provide a strengthened anchor to withstand actions such as impacting the anchor during insertion or applying bending stress to the anchor.
MENISCAL REPAIR DEVICES, SYSTEMS, AND METHODS
Meniscal repair devices, systems, and methods are provided.
CERVICAL CERCLAGE WITH SURGICAL BUTTONS
Embodiments of the present invention provide a cervical cerclage apparatus and a method for performing a cervical cerclage. In an embodiment of the invention, a cervical cerclage apparatus includes, a length of suture and at least two stitched regions formed by the length of suture around an exterior surface of a cervix. The cervical cerclage apparatus further includes at least two surgical buttons attached the length of suture, each surgical button comprising an inner face and an outer face, wherein the inner face of each surgical button are configured to be placed against the exterior surface of the cervix between the stitched regions, wherein at least one of the surgical buttons comprises Progesterone.
Systems, devices, and methods for securing tissue using a suture having one or more protrusions
Systems, devices, and methods are provided for securing soft tissue to bone. One exemplary embodiment of a surgical repair construct includes an anchor, a filament having a snare formed on one end and a collapsible loop on another end, and a suture having a plurality of stationary protrusions formed therein. The suture is configured to be coupled to detached tissue and have its ends passed through an opening in the snare. The snare can be collapsed around the suture such that at least one of the suture protrusions is proximal of the collapsed snare. The anchor can be disposed in bone and the filament coupled thereto. Accordingly, collapsing the snare around the suture couples the tissue to bone, and applying tension to a tensioning limb of the filament can collapse the collapsible loop to incrementally tighten and secure the tissue to bone. Other exemplary systems, devices, and methods for use with soft tissue repair are also provided.
