  • Publication number: 20230285723
    Abstract: One aspect provides a medical guidewire including a core wire extending from a proximal tip of a proximal end section to a distal tip of a distal end section. A polymer layer covers a perimeter surface of at least a portion of the distal end section, the polymer layer covering the distal tip and extending proximally to a proximal end portion defining a proximal edge. A strengthening feature is disposed about a perimeter surface of at least the core wire at the proximal end portion of the polymer layer, the strengthening feature beginning at a location proximally spaced from the proximal edge of the polymer layer and extending distally at least until the proximal edge of the polymer layer, the strengthening feature to prevent damage to the proximal end portion of the polymer layer.

  • Publication number: 20140148858
    Abstract: A transverse connector for coupling between first and second vertebral anchors of a spinal stabilization system. The transverse connector includes a first coupling assembly proximate a first end, a second coupling assembly proximate a second end, a first fastener having external threading configured to threadably engage an internal threaded portion of a housing of the first vertebral anchor, and a second fastener having external threading configured to threadably engage an internal threaded portion of a housing of the second vertebral anchor. Each of the first and second fasteners includes a spherical upper surface, such as a spherically concave upper surface. A spherical surface of each of the first and second coupling assemblies mates with the spherical upper surface of the respective fastener to provide multi-axial rotation of the transverse connector relative to the housings to permit a desired orientation of the transverse connector.

  • Publication number: 20060036265
    Abstract: An apparatus for repairing a tear in an annulus fibrosus of a spinal disc includes a hollow, helically-shaped suturing needle and a retriever. The needle is used to insert a suture along a helical pathway bridging the tear. The retriever is used to retrieve one end of the suture from the inside of the annulus and bring it close the other end of the suture outside the annulus, where the suture can be tensioned and tied to fixate the tear. In other embodiments, multiple sutures are placed with helically-shaped needles of differing dimensions.
