A suture anchor includes a body having a distal end and a proximal end. Projections in the form of ribs or threads are formed on the body for retaining the anchor in a hole formed in bone. An eyelet formed on the distal end of the body accepts suture. The eyelet preferably is formed by a loop of suture. Where the body of the anchor is formed of a polymer, the suture loop can be formed by insert-molding the suture into the body. Tissue is reattached to bone using the suture anchor by securing a length of suture to the tissue, and threading the length of suture through the eyelet on the distal end of the anchor, leaving lengths of suture extending from either side of the eyelet. Installing the suture anchor into the bone wedges the lengths of suture between the suture anchor and the bone, thereby securing the tissue without the need for tying knots. Pullout strength can be enhanced by twisting the lengths of suture prior to installation of the anchor into the bone.

A low-profile clip adapted to secure a listing bead to a foam substrate and is constructed from a material that affords resilience, durability, high resistance to a wide range of temperatures during field use and seat assembly and ease of bead installation with high pull-out strength. The clip includes a base and a pair of legs extending upwardly from the base to a top barb. In this embodiment, the legs each extend upwardly from the base at a first angle of approximately 80 to 85 degrees and therefrom to each of the respective barbs at a second angle, with respect to a plane parallel to the base of approximately 88 to 90 degrees. In this manner the clip exhibits high performance while defining an overall height from tops of the legs to a bottom of the base of approximately ten millimeters or less making the clip particularly desirable for use in modern, thinner foam substrates.

A composite system includes a first component, for instance of metal, and a second component extending at least partly through the first component along an imaginary longitudinal axis of the composite system. The second component contacts, with an at least partially curved, especially cylindrical, outer surface, an inner surface of the first component flushly such that the first component at least sectionally, at least partly, grips around the second component. Joining surfaces of the composite system, which are formed by the mutually contacting surfaces of the two components, are formed in such a manner that the two components exhibit contour portions in the area of these joining surfaces embodied as self-closing, peripheral surfaces. The contour portions fit at least partly into one another, to form a mechanical interference locking effective, at least in part, likewise in the direction of the longitudinal axis. Additionally, the second component, with its outer surface, contacts the inner surface of the first component flushly, such that the two components are mechanically tightly connected together also by means of a frictional locking effective at least partly in the direction of the longitudinal axis. Alternatively, or in supplementation thereof, at least one of the components is subjected at least partly to lastingly elastic, especially mixed plastic-elastic, deformations. The composite system is distinguished by a high pull-out strength, even in the presence of repeatedly arising vibrations in one of the components and is, therefore, especially suited also for use in a vibration-type measurement pickup.

A bone fixation system includes a bone plate having bi-directional combination holes extending therethrough, each hole being composed of a pair of domains and an interconnect which prevents the holes from overlapping. Each of the holes is configured and dimensioned to receive a set of full head bone screws adapted to be anchored into a bone or fragments thereof. The system also includes a pair of bone screws received in at least one of the combination holes, each bone screw having a shaft and a full head and being oriented in non-parallel directions. Various bone plate and screw embodiments are disclosed as is a method for fixating a bone fracture using the fixation system.

The present invention relates to an orthopedic plate for use in repair of a fibula. The plate has a Y-shaped profile which has the contour of a spoon where the bowl includes a terminal pair of arms that form differing angles and lengths relative to the trunk portion of the plate. The arms include locking screw holes where the screws converge toward each other, but do not impinge so as to provide-multiplanar fixation.

A suturing instrument and methods for placing mattress stitches in soft tissues comprises an elongate shaft with a stationary jaw and a movable jaw disposed at a distal end thereof. The movable jaw is coupled to a handle grip at the proximal end of the shaft and is configured to manipulate the movable jaw into open and closed positions respective to the stationary jaw. The jaws are configured to permit atraumatic grasping of soft tissues to be sutured. The stationary jaw is comprised of a serrated face, incorporating apertures through which needles may be driven distally into and through the grasped tissue and into needle capture cans attached to opposing ends of a single strand of suture material. The serrated upper jaw is configured with capture means adapted to accept and capture the needles and suture. The handle is released to open the movable jaw, after which the instrument may be withdrawn, trailing the suture, and leaving a mattress stitch in the grasped tissue.

A suture anchor has a continuous thread spiralling around a tapering central core. At the distal end of the thread, the suture anchor has a starting pitch to facilitate insertion of the anchor into bone. The proximal end of the suture anchor receives at least one strand of suture. At the proximal end, the suture anchor has a large thread surface per turn of thread.

A suture anchor includes a threaded anchor body having a first central bore in communication with a second central bore. The suture anchor includes an internal eyelet formed of a loop disposed at least partially inside the first central bore. The ends extending from the loop are tied together to form at least one knot which is housed in the second central bore provided at the distal end of the anchor body. The knot increases the pullout strength of the suture even in soft bone, provides increased suture fixation, and eliminates the anchor “pull back.”

A spinal implant which is configured to be deployed between adjacent vertebral bodies. The implant has at least one fixation element with a retracted configuration to facilitate deployment of the implant and an extended configuration so as to engage a surface of an adjacent vertebral body and secure the implant between two vertebral bodies. Preferably, the implant is expandable and has a minimal dimension in its unexpanded state that is smaller than the dimensions of the neuroforamen through which it must pass to be deployed within the intervertebral space. Once within the space between vertebral bodies, the implant can be expanded so as to engage the endplates of the adjacent vertebrae to effectively distract the anterior disc space, stabilize the motion segments and eliminate pathologic spine motion. Angular deformities can be corrected, and natural curvatures restored and maintained.

An insert-molded suture anchor has a biodegradable polymer body molded around a loop of suture. A tapered end disposed on the proximal end of the body is received into a recess in the distal end of a hand driver. Anchoring ribs are formed along the remaining length of the anchor. The suture is held securely within the anchor body during the insert molding process. The anchor is produced by placing the suture within an injection mold, and injecting biodegradable polymer into the mold. Using a preferred plication driver, the suture anchor can be utilized for capsular plication procedures.
