Appl. No.:

11/069492

Assignee:

SulphCo, Inc. - Houston TX

International Classification:

H02N 2/00
H01L 41/08

US Classification:

310334, 310314, 31031601, 31031603, 310317, 31032319

Abstract:

The present invention is directed to a high-powered (e. g. , >500 W) ultrasonic generator for use especially for delivering high-power ultrasonic energy to a varying load including compressible fluids. The generator includes a variable frequency triangular waveform generator coupled with pulse width modulators. The output from the pulse width modulator is coupled with the gates of an Isolated Gate Bipolar Transistor (IGBT), which amplifies the signal and delivers it to a coil that is used to drive a magnetostrictive transducer. In one embodiment, high voltage of 0-600 VDC is delivered across the collector and emitter of the IGBT after the signal is delivered. The output of the IGBT is a square waveform with a voltage of +/−600V. This voltage is sent to a coil wound around the ultrasonic transducer. The voltage creates a magnetic field on the transducer and the magnetorestrictive properties of the transducer cause the transducer to vibrate as a result of the magnetic field.

International Classification:

A61B 17/66

US Classification:

606282, 606280, 606283, 606 71

Abstract:

A plating system and method include a bone plate with at least a first vertebral engaging portion and a second vertebral engaging portion connected by flexible intermediate portions to permit translation of the vertebrae to which the bone plate is attached. The bone plate may further include a guide assembly extending between the vertebral engaging portions that permits at least uni-directional translation while enhancing resistance of the bone plate to bending forces.

US Classification:

606250, 606248, 606251, 606252, 606253, 606279

Abstract:

Devices and methods for anchoring one or more elongate connecting members along the spinal column include a transverse linking member positionable through a spinous process in a generally orthogonal orientation to the sagittal plane. At least one coupling assembly is engageable about an end of the linking member extending from the spinous process. The elongate connecting member is engaged to the coupling assembly in a transverse orientation to the transverse linking member.

Assignee:

Warsaw Orthopedic, Inc. - Warsaw IN

International Classification:

A61B 17/80

US Classification:

606282

Abstract:

Devices and methods for spinal fixation employ at least first and second plates that are configured to allow progressive sliding advancement of the plate members toward one another and limit movement of the plate members away from one another after installation. A spring member associated with one bone plate may engage toothed section(s) on the other bone plate. The bone plates may each have arms that are spaced from one another and engaged by corresponding arms on the other bone plate. There may be more than two bone plates, with multiple restricted movement regions.

Assignee:

Warsaw Orthopedic, Inc. - Warsaw IN

International Classification:

A61B 17/80

US Classification:

606295, 606289, 606280

Abstract:

A plating system and method include a bone plate with at least a first hole therethrough between an upper surface and a lower surface of the bone plate to receive an anchor for engaging the plate to a bony segment. The system and method also include a retaining member engageable to the bone plate that includes a head with an outer perimeter having a ramped or camming portion that is positionable in contact with the anchor to prevent the anchor backing out of the first hole.

International Classification:

A61B 17/70

US Classification:

606278, 606246, 606279

Abstract:

Skeletal stabilization systems include a base, a longitudinal member, and a retaining member. The base includes an engagement surface with a surface area that is positionable in contact with a bone to atraumatically or traumatically engage the base to the bone. The retaining member engages the base to retain the longitudinal member relative to the base so that the longitudinal member can provide a desired stabilization effect to one or more adjacent bony portions.

US Classification:

606270, 606266, 606306

Abstract:

The present application is directed to multi-axial screw assemblies to connect a longitudinal member to a vertebral member. In one embodiment, the multi-axial screw assembly includes a screw comprising a threaded shank and an enlarged head. The assembly may also include a body with an upper channel sized to receive the longitudinal member, a lower chamber to receive the head. The body is constructed to maintain the head in the lower chamber.
