International Classification:

G01L 7/08

US Classification:

73715, 73718, 73724

Abstract:

A pressure sensing device () is shown having a ceramic capacitive sensing element () received in a chamber formed in a hexport housing (). The hexport housing has a fluid passageway () communicating with a recessed chamber () formed in a bottom wall circumscribed by an annular platform shoulder (). A thin flexible metal diaphragm () is hermetically attached to the bottom wall along the platform shoulder. A curable adhesive resin having a thermal coefficient of expansion and modulus of elasticity appropriately matching that of sensing element (), such as polyurethane, is cast between the sensing element () and the metal diaphragm () forming, when cured, a layer bonded to both members resulting in a sensor that is effective in monitoring negative as well as positive fluid pressures. In one embodiment a ring is used to define layer laterally and in a second embodiment an insulator sleeve () and shield sleeve () which receives pressure sensing element () each have an open end with an inwardly extending lip () that define layer laterally.

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.
