  • Patent number: 10219849
    Abstract: A system for supporting ribs is provided that includes first and second reinforcing members, fasteners, and closure members. Each reinforcing member may be attached to a respective rib via fasteners such that the reinforcing member spans one or more fractures of the ribs. In addition to individually holding the portions of the rib bone together to allow the fracture to heal, however, the reinforcing members may be used on rib pairs such that closure members may be wrapped around or extended between the rib pair in an effort to stabilize the ribs. By providing extended regions configured to receive closure members, healing of the ribs may be promoted and facilitated without creating unnecessary other pain to the patient, as the rounded portions serve to keep the closure members away from the neurovascular bundles associated with the ribs.

  • Patent number: 7857840
    Abstract: An improved fastener apparatus includes an outer sleeve which is moved into a patient's body tissue. A distal end portion of the outer sleeve is expanded in the patient's body tissue. An inner sleeve is moved axially through the outer sleeve and a distal end of the inner sleeve is expanded in the patient's body tissue. The fastener apparatus may be provided with an external thread convolution on either or both of the inner and outer sleeves. During expansion of the distal end portion of either the inner or outer sleeve, a proximal end portion of the outer sleeve may be gripped and pulled to offset forces applied to the distal end portion of one of the sleeves. Although inner and outer sleeves may advantageously be utilized, the fastener apparatus may be constructed with only a single sleeve if desired.

  • Patent number: 7785357
    Abstract: An expanding plug for tendon fixation features a two-part system in which an expansion pin fits inside a fixation sleeve. The fixation sleeve is configured to expand diametrically to achieve interference fixation of a graft tendon inside of a bone tunnel. Fixation sleeve expansion is urged by a two-step engagement of the expansion pin. The tendon graft is assembled to the expanding bolt and situated within a bone tunnel. Passing suture is used to pull a joint-line end of the expansion pin into the tunnel to partially expand the fixation sleeve at the joint-line end. Pulling a graft end of the expansion pin toward the joint line expands the fixation sleeve to place the expanding plug in the fully deployed configuration.

  • Publication number: 20100114181
    Abstract: A fixing element, in particular a peg, for fixing bone fragments or the like has at least two outer sub-elements extending parallel to each other and an expansion element. The sub-elements and expansion element are of such a configuration and so arranged relative to each other that the fixing element is to be transferred by means of the expansion element from a compact condition into an expanded condition. The two sub-elements define a cavity for the expansion element and have sliding surfaces for the expansion element. The sliding surfaces extend parallel to the longitudinal axis of the fixing element and, in the compact condition of the fixing element, are at a mutual spacing smaller than the mutual spacing of sliding surfaces of the expansion element, that also extend parallel to the longitudinal axis of the fixing element.

  • Patent number: 7695494
    Abstract: A device for attaching connective tissue to bone has a longitudinal axis and comprises an annular toggle member and a body member disposed distally of the toggle member, such that there is an axial space between the toggle member and the body member. The toggle member is movable between an undeployed position wherein the toggle member has a smaller profile in a direction transverse to the axis and a deployed position wherein the toggle member has a larger profile in the direction transverse to the axis. When installed in a desired procedural site, in suitable bone, suturing material extends axially through a center aperture in the annular toggle member, without being secured to or contacting the toggle member. This approach permits a suture attachment which lies entirely beneath the cortical bone surface, and which further permit the attachment of suture to the bone anchor without the necessity for tying knots, which is particularly arduous and technically demanding in the case of arthroscopic procedures.
