International Classification:

A61B 17/56
A61B 17/58
A61B 17/80
A61B 17/88
A61F 2/30

US Classification:

606288, 606 71, 606281

Abstract:

The present invention discloses a device and method to establish and maintain bone stabilization and enhance post-operative healing in a surgical site, such as the cervical spine of a patient, with reduced risk of erosion or other injury to adjacent anatomic structures from extrusion of surgical fasteners, such as bone screws. The surgical stabilization system according to the present invention provides for the secure plating of structures such as adjacent vertebral bodies with allowance for selective postoperative motion of the surgical fasteners used to secure the plate. Such motion imparts benefit from increased translational response and remodeling in the course of bone healing, thus resulting in strengthened fusion.

International Classification:

A61B 17/58

US Classification:

606280, 606246

Abstract:

A sternal closure device is provided, comprising a first plate having a bone fixation region with at least one countersunk aperture for receiving a fastening means for affixing the first plate to one side of the sternum, and a locking region with at least one protruding aligning member; a second plate having a bone fixation region with at least one countersunk aperture for receiving a fastening means for affixing the second plate to the opposite side of the sternum, and a locking region dimensioned to contact at least a portion of the locking region of the first plate; and a rotating member that engages with the aligning member(s) on the first plate for holding the first and second plates together to secure the opposite sides of the sternum. The first and second plates can be separated by reversibly disengaging the rotating member from the aligning member(s).

International Classification:

A61B 17/70

US Classification:

606249

Abstract:

Various interspinous process spacing devices and associated methods are provided for treating spinal disease. In one embodiment, an interspinous process spacing device includes a first attachment side and a second attachment side, each attachment side including one or more slots formed therein and positioned proximate one end for receiving fasteners extending inwardly from a second interspinous process spacing device. The device further includes a spacer tray extending from the first attachment side and slideably insertable through a spacer tray slot formed in the second attachment side, wherein the spacer tray is adapted to retain adjacent spinous processes in a spaced apart orientation, and wherein at least a portion of the spacer tray has a longitudinally arcuate shape adapted to facilitate angled insertion of the spacer tray through the spacer tray slot. The device further includes securing means for securing the second attachment side relative to the first attachment side.

Abstract:

Various embodiments described herein provide devices and associated methods for treating spinal disease by implanting one or more interspinous process spacing devices. In one embodiment, an interspinous process spacing device includes a first attachment side and a second attachment side, whereby each attachment side includes one or more slots formed in the outer surface and oriented proximate one end for receiving fasteners extending inwardly from a second interspinous process spacing device. The device further includes a spacer tray positioned between the first attachment side and the second attachment side, the spacer tray extending from the first attachment side and slideably insertable through a tray slot formed in the second attachment side, wherein the spacer tray is adapted to retain adjacent spinous processes in a spaced apart orientation. The device further includes securing means for securing the second attachment side relative to the first attachment side, wherein, upon securing the second attachment side relative to the first attachment side, the interspinous process spacing device is engaged with the adjacent spinous processes.

International Classification:

A61B 1000

US Classification:

600562

Abstract:

An automated tissue sampling device is disclosed which permits its needles to be cocked either simultaneously or sequentially and can be cocked with only one hand. The cocking mechanism is arranged so as to virtually eliminate the possibility that the needles will be cocked in the wrong sequence. The physician can readily confirm, either visually or tactilely, whether the device is uncocked, half cocked, or fully cocked. The disclosed tissue sampling device also comprises two different trigger buttons, one adjacent the front end of the device and the other at the rear, and manipulating either of the two trigger buttons will actuate the device.
