  • Patent number: 8721566
    Abstract: This invention is a minimally-invasive device, including bone-moving members and motion-measuring members, that can help surgeons to obtain objective, quantitative information concerning spinal flexion, extension, lateral bending, decompression, compression and torsion in order to select the best therapy for each patient. The prior art does not offer surgeons the opportunity to objectively and independently measure each of these movements. As a result, currently there is tremendous variation concerning which therapies are selected for which conditions. It is very unlikely that quality is being optimized and costs are being best managed with such high variation in practice patterns. This variation may be greatly reduced by the availability of objective information concerning spinal motion from this device. In this manner, this device can help surgeons to select the optimal therapy, to improve the quality of care, and to reduce the risk and expense of unnecessary spinal procedures and hardware.

    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: 8574232
    Abstract: An external fixation connection rod that allows for rapid and gradual length adjustment. In some embodiments, the fixation connection rod includes an inner sleeve received within a telescopic rod to allow for rapid adjustment of an overall length of the fixation connection rod. In some embodiments, the fixation connection rod includes an adjustment mechanism to allow for gradual adjustment of the overall length of the fixation connection rod by lengthening or shortening a threaded elongated member within the inner sleeve, and the adjustment mechanism includes a first rotation member, a second rotation member, and a spring. Distal translation of the first rotation member relative to the second rotation member allows the adjustment mechanism to move from a first, locked position to a second, unlocked position, allowing the first rotation member and the second rotation member to rotate about the inner sleeve and the threaded elongated member during gradual adjustment.

  • Publication number: 20130274801
    Abstract: A cross connector for connecting elongated fixation elements, such as spinal fixation rods, includes a central body and one or more actuators. The rod to rod connector may include a first lever and a second lever coupled to the central body. The first lever may include a free end separated from the central body by a first channel. The second lever may include a free end separated from the central body by a second channel. The one or more actuators may be operable to pivot the first and second levers into a relatively closed position. When the first and second levers are in the relatively closed position, the free ends of the first and second levers are moved toward one another and toward the central body to contract the first and second channels.

  • Publication number: 20130268003
    Abstract: A spinal implant includes a first rod, a second rod, and connector. The first rod has a first end configured to be connected to a first bone, a second end opposed to the first end, and a longitudinal axis that passes through the first and second ends. The second rod has a first end configured to be connected to the second bone, a second end opposed to the first end. The second rod is parallel to the longitudinal axis and non-coaxial with the first rod, and at least a portion of the second end of the second rod overlaps the second end of the first rod. The connector connects the second end of the first rod to the second end of the second rod, and is configured to urge the first rod and the second rod in opposed directions that are parallel to the longitudinal axis.

  • Publication number: 20130268004
    Abstract: A connector for engaging two or more rods is disclosed. The connector includes a main body, at least two medial bodies and a compression mechanism. Generally, the connector provides for easy “snap-fit” lateral insertion of the rods into rod openings defined between the medial bodies and the main body. The snap-fit is achieved through a spring bias exerted by the compression mechanism. The compression mechanism may also be configured to lock the rods within the openings, such as through the use of a fastener.

  • Publication number: 20130253586
    Abstract: A transconnector for use in interconnecting a pair of longitudinal spinal rods in a spinal fixation procedure. The transconnector includes a bridge member and first and second spinal rod engaging members. The bridge member may include first and second members, wherein the first and second members are moveably associated with one another so that the distance between the first and second spinal rod engaging members can be adjusted. The first and second spinal rod engaging members include a rod receiving channel for receiving one of the spinal rods therein. The spinal rod engaging members may be articulating in, for example, the yaw and roll positions or non-articulating with respect to the bridge members. The spinal rod engaging members preferably include a spring, for example, a spring washer, to provide an opposing force so that the spinal rod engaging members can provisionally snap onto the spinal rods.

  • Patent number: 8535335
    Abstract: A needle-coupled parallel mechanism is provided. The needle-coupled parallel mechanism is structurally improved so as to have a broad working area and a high precision. The needle-coupled parallel mechanism comprises a fixedly positioned frame, a main shaft, three first links, three second links, and a needle. The main shaft is arranged so as to be movable relative to the frame. One end of each of the first links is connected to the frame between both ends of the main shaft and the other end thereof is connected to one end of the main shaft. One end of each of the second links is connected to the frame between both ends of the main shaft and the other end thereof is connected to the other end of the main shaft. The needle is linearly movably coupled to the main shaft to perform a predetermined operation on a target object. Each of the first links and the second links has at least three joints selected from a prismatic joint, a 1-axis revolute joint, a 2-axis revolute joint and a spherical joint.

  • Patent number: 8491636
    Abstract: A system and method for controlling the inflation, ablation, and deflation of a balloon catheter. The system includes a balloon catheter, a console, a pressurized gas or liquid inflation source, and an umbilical system to deliver pressurized coolant to the balloon catheter. The system may include controller that monitors the amount of pressure and volume within the balloon catheter. During inflation, the pressure and/or volume of fluid within the balloon is maintained at a target amount in order to provide sufficient mechanized pressure against the desired target region. The system limits the inflation pressure such that a safe quantity of gas would be released should a leak occur. If the amount falls below a certain threshold level, gas or fluid egress is presumed and the inflation process is halted.
