An artificial functional spinal unit is provided comprising, generally, an expandable artificial intervertebral implant that can be placed via a posterior surgical approach and used in conjunction with one or more artificial facet joints to provide an anatomically correct range of motion. Expandable artificial intervertebral implants in both lordotic and non-lordotic designs are disclosed, as well as lordotic and non-lordotic expandable cages for both PLIF (posterior lumber interbody fusion) and TLIF (transforaminal lumbar interbody fusion) procedures. The expandable implants may have various shapes, such as round, square, rectangular, banana-shaped, kidney-shaped, or other similar shapes. By virtue of their posteriorly implanted approach, the disclosed artificial FSU's allow for posterior decompression of the neural elements, reconstruction of all or part of the natural functional spinal unit, restoration and maintenance of lordosis, maintenance of motion, and restoration and maintenance of disc space height.

Disclosed is a holding device including: a telescopic handle having axially opposed front and rear ends and constructed of at least two separate shafts, of which a front-side separate shaft axially fits within a rear-side separate shaft being a hollow cylinder; and a support member provided at the front end of the telescopic handle for attachment of a cleaning wiper. The front-side separate shaft has an axially extending elastic arm and an engaging projection provided at a leading end of the elastic arm, while the rear-side separate shaft has a through-hole passing through a cylinder wall thereof, in which the engaging projection engages when the front-side separate shaft projects from the rear-side separate shaft by a predetermined length. Pressing the engaging projection, which engages in the through-hole, from outside the rear-side separate shaft permits release of the engaging projection from the through-hole.

A clamping assembly having a top and bottom and front and back orientation, at least one optical axis, and a pre-actuated state in which a fiber is not secured to the clamping assembly and a post-actuated state in which a fiber is secured to the clamping assembly, the clamping assembly comprising: (a) a housing; (b) a platform disposed in the housing and being fixed therein both radially and axially, the platform defining a fiber-receiving channel along the optical axis to receive at least one fiber, at least a portion of the fiber-receiving channel being accessible from the top; (c) a first cam member disposed in the housing above and adjacent to the fiber-receiving channel, the first cam member being radially actuateable within the housing, the first cam member having a first cam surface; (d) a second cam member disposed in the housing and axially slidable therein, the second cam member having a second cam surface adjacent the first cam surface and configured such that, upon forward motion of the second cam member relative to the first cam member, the first cam member is urged downward as a result of a camming action between the first and second cam surfaces; and (e) an actuator disposed slidably within the housing behind and adjacent to the second cam member and configured such that, when moved forward, it forces the second cam member forward relative to the first cam member.

An assembly allowing retraction of soft tissue away from a reference plane; the assembly including at least one retracting element each having a distal end with a formation allowing anchorage of the at least one retracting element. The assembly also includes a proximal end of the at least one retracting element capable of movement through at least one degree of freedom relative to the anchorage.

A biosignal measurement device includes an electrode and a signal processing member. The electrode includes an insulation sheet having a hole, a device contact portion provided on the top surface of the insulation sheet and a body contact portion provided on the bottom surface of the insulation sheet, the device contact portion and the body contact portion electrically connected to each other via the hole. The signal processing member includes an externally exposed terminal to make surface contact with the device contact portion, an analog signal processing unit, an A / D signal converter and a digital signal processing unit. Also, the device contact portion and the body contact portion are formed of a material which is both conductive and adhesive. Accordingly, the signal processing member may be directly attached. Noise may be reduced. Also, a biosignal may be accurately measured.

Chimeric flaviviruses that are avirulent and immunogenic are provided. The chimeric viruses are constructed to contain amino acid mutations in the nonstructural proteins of a flavivirus. Chimeric viruses containing the attenuation-mutated nonstructural genes of the virus are used as a backbone into which the structural protein genes of a second flavivirus strain are inserted. These chimeric viruses elicit pronounced immunogenicity yet lack the accompanying clinical symptoms of viral disease. The attenuated chimeric viruses are effective as immunogens or vaccines and may be combined in a pharmaceutical composition to confer simultaneous immunity against several strains of pathogenic flaviviruses.

A lens in accordance with the present invention includes an accommodating cell having two chambers with at least one chamber filled with optical fluid with the refractive index matching the refractive index of the accommodating element separating them. The accommodating element has a diffractive surface with surface relief structure that maintains its period but changes its height due a pressure difference between the chambers to redirect most of light that passes through the lens between different foci of far and near vision. The invention also includes a sensor cell that directly interacts with the ciliary muscle contraction and relaxation to create changes in pressure between the accommodating cell chambers that results in changing surface relief structure height and the lens accommodation.
