Collapsible, Rotatable And Expandable Spinal Hydraulic Prosthetic Device
US Patent:
6375682, Apr 23, 2002
Filed:
Aug 6, 2001
Appl. No.:
09/922161
Inventors:
Lewis W. Fleischmann - Pikesville MD 21208
Christopher Galuardi - Owings Mills MD 21117
Christopher Galuardi - Owings Mills MD 21117
International Classification:
A61F 244
US Classification:
623 1712, 623 1715, 623 1716
Abstract:
A spinal prosthetic device ( ) which is hydraulically expanded or retracted, either pre-implantation or in-situ, thereby being adjustable for the exact intravertebral axial spacing required for the patient. Thrust bearing members ( ) are positioned between the vertebra engaging members ( ) and a pair of bellows ( ), allowing the collapsible/expandable bellows ( ) to be rotated with respect to the vertebra engaging members ( ). The device ( ) can be readjusted, on an out-patient basis, months after initial implantation. The spinal prosthetic device ( ) offers all degrees of motion afforded by the anatomical spinal disc and by virtue of incorporating no rubbing contact of any parts, exhibits and infinite working life. The spinal prosthetic device ( ) reproduces the same hydraulic load bearing capability as the nucleus pulposis and flexural freedom of movement similar to the annulus fibrosis.
Rotatable And Reversibly Expandable Spinal Hydraulic Prosthetic Device
US Patent:
6981989, Jan 3, 2006
Filed:
Apr 22, 2003
Appl. No.:
10/419899
Inventors:
Lewis W. Fleischmann - Pikesville MD, US
Christopher Galuardi - Owings Mills MD, US
Christopher Galuardi - Owings Mills MD, US
Assignee:
X-Pantu-Flex DRD Limited Liability Company - Lutherville MD
International Classification:
A61F 2/44
US Classification:
623 1711, 623 1712, 623 1714
Abstract:
An improved spinal intervertebral prosthetic device that offers all degrees of motion afforded by the anatomic spinal intervertebral disc, and by virtue of the incorporation of a dashpot assembly mechanism within reversibly displaceable bellows, provides hydraulic load bearing capability as well as limiting the maximum pressure that can be exerted on the bellows assembly by limiting the compression stroke of the device. The dashpot assembly also increases resistance to lateral shear loading in excess of the bellows convolutions acting alone. The spinal intervertebral prosthetic device absorbs varying axial loads via hydraulic pressure transfer to the bellows convolutions which can flex in a spring-like fashion. Rotational coupling of the upper crown plate and center bearings plate permits normal twisting movements, and spinal flexural freedom is provided by the bellows that are interposed between the center bearings plate and the lower crown plate.
Collapsible, Rotatable, And Tiltable Hydraulic Spinal Disc Prosthesis System With Selectable Modular Components
US Patent:
7419505, Sep 2, 2008
Filed:
Apr 21, 2005
Appl. No.:
11/110893
Inventors:
Lewis W. Fleischmann - Pikesville MD, US
Christopher Galuardi - Owings Mills MD, US
Christopher Galuardi - Owings Mills MD, US
International Classification:
A61F 2/44
US Classification:
623 1711, 606 99
Abstract:
A modular hydraulic spinal intervertebral prosthetic device offering individualized optimization of an implantable disc prosthesis by having selectable crown plates modules with differing lordosis angles and differing cross-sectional profiles, and selectable bellows cartridges having differing load-bearing capabilities. The device offers substantially full physiological degrees of motion, and by the incorporation of both a dashpot mechanism and a biasing element within reversibly displaceable and tiltable bellows provides hydraulic load bearing capability. The bellows assembly is advantageously pre-loaded to sub-atmospheric pressure. The dashpot further increases resistance to lateral sheer loading beyond the bellows convolutions acting alone. Rotational coupling of the upper crown plate and center bearings plate permits normal twisting movements, and spinal flexural freedom is provided by the bellows interposed between the center bearings plate and the lower end plate. The bellows also provides a hermetic seal which prevents any wear debris from migrating to the surrounding body tissue.
