  • Patent number: 8430911
    Abstract: An implantable spinous process fixation device includes a first plate component having an elongated plate and front and back cross plates extending at right angle to the front and back of the elongated plate, respectively, a top pivoting plate and a bottom pivoting plate. The top and bottom pivoting plates are configured to pivot around an axis perpendicular to the front and back cross plates and the elongate plate has an inner surface facing an inner surface of the top pivoting plate and an inner surface of the bottom pivoting plate.

  • Publication number: 20120303124
    Abstract: A bone fusion device provides stability to bones during a bone fusion period. The bones include, for example, the vertebrae of a spinal column. The bone fusion device comprises one or more extendable tabs attached to the bone fusion device by associated rotating means. The bone fusion device is preferably inserted by using an arthroscopic surgical procedure. During arthroscopic insertion of the device, the tabs are pre-configured for compactness. In this compact configuration, the tabs are preferably deposed along and/or within an exterior surface of the bone fusion device. After the bone fusion device has been positioned between the bones, one or more tab(s) are extended. In the preferred embodiment, the position of each tab is related to a positioning element and extending blocks. Typically, the tabs advantageously position and brace the bone fusion device in the confined space between the bones until the bones have fused.

  • Patent number: 8231677
    Abstract: An artificial disc prosthesis is provided. The prosthesis enables spinal segment alignment by having a variable height across its surface. The variable height is achieved by an asymmetric artificial nucleus or by at least one variable height end plate. The prosthesis may have a central keel on one end plate and an offset pair of keels on a second end plate. The nucleus may engage a slot or trough in an inner surface of an end plate. The trough can be open on the posterior or anterior end to allow the nucleus to slide into the trough without undue distraction of adjacent vertebrae. The nucleus can be prevented from moving out of the trough by inserting a stop in the trough.

  • Patent number: 7871426
    Abstract: An implantable spinous process stabilization assembly includes a body, a bent arm and a straight arm. The body includes first and second crosspieces arranged parallel to each other, a first plate extending in a direction at right angle to first ends of the first and second crosspieces, first and second rings extending from second ends of the first and second crosspieces, respectively and a second plate extending from a base of the first and second rings, at right angle to the first and second crosspieces and in an opposite direction to the first plate's direction. The bent arm and the straight arm are configured to pivot around an axis perpendicular to the first and second rings and to set first and second pivot angles with the first and second plates, respectively, thereby defining first and second spaces configured to receive and lock onto first and second spinous processes, respectively.

  • Patent number: 7811310
    Abstract: The present invention relates to a locking mechanism and method of locking the relative positions of a fixation device like a bone screw and of a stabilization device like a rod. The locking mechanism includes a seat, a washer and a cap. The seat includes a bottom portion configured to receive the fixation device such that a socket of the bottom portion engages part of the fixation device and prevents the fixation device from passing entirely therethrough. The seat further includes a side portion configured to receive the stabilization device, a washer and a cap. When the washer and cap are fully engaged with the seat, the fixation device may be locked independent of the stabilization device. The locking mechanism may also include a locking element for locking the stabilization device.

  • Publication number: 20100160980
    Abstract: A locking mechanism (100) and method of fixation, such as the fixation of a fixation device (104) like a bone screw and of a rod (106) to the spine. The locking mechanism (100) includes a body (102), an insert (108, 308), a rod seat (110, 310) and a set screw. The body (102) includes a bottom portion (114) configured to receive the fixation device (104) and the insert (108, 308) but prevents the insert (108, 308) and fixation device (104) from passing therethrough once the insert (108, 308) and fixation device (104) are engaged. The body (102) further includes a side portion (120) configured to receive the rod (106). Between the rod (106) and the insert (108, 308) is a rod seat (110, 310).
