  • Patent number: 7338491
    Abstract: The present invention relates to a locking mechanism and method of fixation, such as the fixation of a fixation device like a bone screw and of a stabilization device like a rod to the spine. The locking mechanism includes a seat and a locking element. 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 and a locking element. The locking element, when fully engaged with the side portion of the seat, causes locking of the relative positions of the fixation device and the stabilization device.

  • Publication number: 20080051787
    Abstract: A minimally invasive, percutaneous system that allows for dynamic stabilization of the spine is provided, together with methods of using the system. The system comprises a first bone anchoring member that is anchored in a first vertebra, and a second bone anchoring member that is anchored in a second, adjacent, vertebra. The first and second bone anchoring members include a first head portion and second head portion, respectively, that are designed to hold first and second ends of a flexible, elongated member, or cord. In certain embodiments, the cord is provided with a stiffened, relatively inflexible, end portion that is fixedly attached to the cord and that facilitates threading of the cord through the first and second head portions.

  • Publication number: 20070270840
    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.

  • Publication number: 20040087914
    Abstract: A system for grasping, holding, stabilizing, and selectively releasing tissue with minimal damage to the tissue. The system can further include a device that signals entry into the epidural space. A tubular member is provided having at a distal tip an annular surface surrounding a terminal port and at least one barb projecting at an angle from the annular surface for grasping and controlling the tissue. Each barb is formed having a sharp edge configured to grasp the tissue as the tubular member is rotated about its longitudinal axis. One implementation of the system includes a plurality of unidirectional barbs spaced around the annular surface. The system can further include an indicator mechanism that gives a visual and a tactile indication of when the tubular member, such as a cannula, encounters and penetrates tissue. The system facilitates the appropriate placement of an epidural or subdural catheter or patch of any kind.

  • Patent number: 6413927
    Abstract: A process for stabilising particulate alkali metal percarbonate involves coating it with an aqueous solution, preferably concentrated, of a non-reducing oligomeric saccharide, preferably sucrose and especially together with an inorganic salt co-coating agent. The preferred co-coating agents are alkali metal silicate, sulphate, carbonate and carbonate chloride. Coated percarbonate is provided having an excellent combination of solubility, and stability, even with low amounts of coating agent.
