  • Patent number: 8986287
    Abstract: Instrument handles are adjustable relative to an end effector of the instrument. The handles may be releasably locked in selected positions and/or orientations relative to the end effector. When the lock is released, the handles may be moved to a different position and/or orientation relative to the end effector, and locked in place. The handles may pivot relative to the end effector around one or more joints. The handles may pivot about an axis of a hinge joint or a point of a ball and socket joint. The axis of the hinge joint may be aligned parallel or perpendicular to a center longitudinal axis of the end effector, or of a shaft between the handles and the end effector.

  • Publication number: 20150080964
    Abstract: An apparatus is designed to attach an implant to bone in a manner that permits rotational adjustment of the implant about multiple axes prior to securement via the apparatus. The apparatus includes separate rotational and translational fasteners that can be individually locked to independently restrict rotation and translation of the implant relative to the bone. The rotational fastener includes an interpositional member, an expandable engagement member, and a rotational locking member that urges the expandable engagement member to advance along the interpositional member. The resulting expansion of the engagement member causes it to engage the implant. The rotational fastener is slidable along a fixation member implanted in the bone until the translational fastener is applied to restrict relative translation between the rotational fastener and the bone.

  • Patent number: 8926700
    Abstract: Superior and/or inferior facets of one or more facet joints may be replaced by superior and/or inferior facet joint prostheses. In one embodiment, a kit of superior or inferior prostheses is provided, in which the prostheses have at least two dimensions that vary among members of the kit independently of each other. Each prosthesis may have a bone engaging surface having a surface that is polyaxially rotatable against a corresponding resection of a vertebra. Each prosthesis may also have an articulating surface shaped such that, after attachment to the spine, the replaced or partially replaced facet joints provide a larger medial-lateral range of motion when the spine is flexed than when the spine is extended. Crosslinks may be used to connect left and right prosthesis together in such a manner that they are stabilized in a position in which they are seated directly against the vertebra.

  • Patent number: 8920404
    Abstract: A catheter tip designed to reduce the outflow velocity and/or directional momentum of fluid being infused by a catheter having such a tip. In one variation, a plurality of channels is provided at the distal portion of the catheter to increase the outflow cross-sectional area. In another variation, the diameter of the catheter at its distal portion where the fluid exits is increased. In yet another variation, a bullet-shaped nose is implemented which may decrease turbulence at the distal end of catheter tip. The low velocity outflow catheter tip may also be implemented on a dual lumen catheter, such as a hemodialysis catheter, to reduce recirculation rate. Various device configurations and methods for such implementations are also disclosed.

  • Patent number: 8900273
    Abstract: A fixation system is designed to lock an elongated member within a housing member, permitting positional and/or orientational adjustment of the elongated member prior to locking. The system includes a housing member, a slotted spherical collet, an elongated member, and may include a tapered wedge, which may be a discrete component or formed as part of the elongated member. The housing member and/or elongated member may be implantable. The elongated member may be positioned in the wedge, the wedge in the collet, and the collet in the housing such that when compression force is applied to the wedge and the collet, the wedge contracts about the elongated member and the collet expands to engage the housing, thus locking the elongated member relative to the housing. The collet may have a tapered channel with a degree of taper equal to the tapered wedge. The collet may have multiple slots to allow uniform radial expansion and compression.

  • Publication number: 20140324102
    Abstract: Facet joint replacement implants may be designed for use on multiple adjacent vertebral levels. Each superior implant may have a substantially semispherical concave surface, and each inferior implant may have a cooperating semispherical convex surface that is deformable to enable it to be pressed into the superior implant concave surface to fix the relative orientations of the superior and inferior implants. Thus, the inferior implant may be attached to the same pedicle as the superior implant, but may also be oriented independently of the superior implant and then fixed in position. Similar mounting structures may be used to attach one or more fusion implants to a level adjacent to that of a facet joint replacement implant.

  • Publication number: 20140249580
    Abstract: A crosslink is provided for securing orthopedic implants, such as facet joint replacement implants, together. The crosslink has a pair of implant coupling components, a pair of rod coupling components, a rod, and a pair of fasteners. Each facet joint implant may include a semicylindrical interface received in a resilient member of the corresponding implant coupling component to permit relative cephalad/caudal adjustment between the crosslink and the implants. The resilient members grip the semicylindrical interface of the implant to enable at least temporary attachment of the implant coupling components to the implants independently of the rod. Clocking features on the semicylindrical interfaces and on the interfacing areas of the implant coupling components and rod coupling components may limit assembly of the crosslink to discrete relative orientations and prevent play after assembly. The fasteners secure the rod coupling components to the rod at the desired positions along the rod.
