  • Publication number: 20150327849
    Abstract: Techniques and reconstruction systems for knotless tissue fixation using a driver with a cannulated interference device or fixation device preloaded on the shaft of the driver. An eyelet, adjustable in size, is formed of a loading suture provided at the distal end of the driver shaft. A working suture attached to the tissue to be fixed is passed through the eyelet. The size of the eyelet is adjusted by the user once the working suture is passed through the eyelet, to capture the working suture with the eyelet. The cannulated interference device is then advanced down the shaft to secure the working suture in a bone socket.

  • Publication number: 20150297274
    Abstract: A tensioning construct with a tape securely attached to a locking button provided with a securing mechanism in the form of a trap door-like mechanism. The tape is looped so that the looped portion of the tape is passed around a feature of the button to allow easy sliding of the tape. One free end of the tape is fed through the securing mechanism (trap door) of the locking button while the other free end is fixed to the locking button. The button self-engages without the need of a locking instrument, to lock the tape as it is tightened during the cerclage repair. The tensioning construct may be provided as a pre-assembled construct.

  • Patent number: 9089363
    Abstract: A cannula with a tri-slot dam assembly including two primary dams as the main fluid seal and an adjacent outer “baffle-like dam” that prevents fluid pressure build-up and allows the fluid to leak out and not squirt out of the cannula. The baffle-like dam has a body formed of a low profile material and is provided with a plurality of small through holes or perforations to allow fluid to gently leak out. Fluid that enters the outer chamber leaks out of the through holes so that the fluid pressure between the baffle and the primary dams is very low. A spacer is optionally provided between the two primary dams and the outer dam to prevent the dams from interfering with each other and allow them to remain open.

  • Publication number: 20150201929
    Abstract: Apparatus and methods for tissue fixation/attachment/reattachment using a knotless tensionable suture construct. The knotless tensionable suture construct is a self-tensioning suture loop that can be tensioned and retensioned after the repair and can be cycled few times. The self-tensioning suture loop is formed of: (i) a simple metal surgical needle with a thin loop off the base of it to allow suture to slide through it; (ii) a single strand of surgical suture which can be of various sizes and colors; (iii) a large knot which is tied to create a large bulge to fix the construct to the device (this can be a knot or secondary piece of material, like a button); (iv) a splice formed by the single strand of suture going back through itself, the splice locking the suture in place; and (v) a suture tail that is pulled to reduce the loop size of the construct and tension the repair.

  • Publication number: 20150032155
    Abstract: A hybrid monofilament/braided surgical suture that combines a monofilament with a braided construction. The hybrid surgical suture may be formed by braiding yarns of high tenacity fibers tightly over a core in the form of a monofilament yarn. The monofilament may be any type of material, for example, a nylon, silk, polyester, polyethylene or polypropylene filament, among many others. The stiffness properties of the hybrid surgical suture allow the suture to be pushed through small and very small diameter tubes and cannulations (such as Lasso instruments, for example) yet fix securely with existing fixation devices (such as knotless suture anchors like PushLock® anchors).

  • Publication number: 20140128921
    Abstract: A bone plate configured to accommodate flexible strands (flexible loops) attached to soft tissue to be attached to bone. The bone plate has a plurality of recessed eyelets on the distal edge of the plate, to allow the user (surgeon) to pass a flexible strand through the recessed eyelets and reattach the soft tissue to the plate at the anatomical location where the tissue was dissected. The recessed eyelets may have various shapes, forms and configurations and may be provided on or within a surface of the bone plate in any number, depending on the characteristics of the fractured bone or bone segments, or of the plate design. The eyelets preferably receive a flexible strand for fixation of soft tissue to the bone plate.

  • Patent number: 8444680
    Abstract: A bone plate with a new design that prevents the bushing from rotating and/or dislodging from the screw hole during screw insertion. The plate is provided with through-holes having internal walls with at least one flat that is configured to align with a corresponding flat provided on the outer wall of the bushing. The bushing is inserted by orienting the bushing in a direction perpendicular to the through-hole of the plate so that the center of the bushing is aligned with the center of the through-hole and the flat on the bushing is aligned with the flat on the through-hole of the bone plate. The bushing is introduced into the through hole until the centers are aligned, and then the bushing is rotated about 90 degrees so that the bushing is captured within the through-hole of the plate. Once captured, the bushing cannot rotate, dislodge from, or come out of the plate unless the bushing is turned 90 degrees.
