Abstract:
An implantable prosthesis is described having a pair of opposed shells and a central body disposed between the opposed shells wherein the central body and the shells cooperate to limit the motion of the central body with respect to the shells. An assembly for preparing a disc space for the implantation of a prosthesis is further described having a plurality of instruments cooperating to guide a tool associated with the assembly.
Abstract:
Devices, systems and kits for repairing, replacing and/or augmenting natural facet joint surfaces and/or facet capsules are disclosed. An implantable facet joint device (800) of one embodiment comprises a cephalad facet joint element and a caudal facet joint element. The cephalad facet joint element includes a member adapted to engage a first vertebra, and an artificial cephalad bearing member (820). The caudal facet joint element includes a connector (810) adapted for fixation to a second vertebra at a fixation point and an ' artificial caudal bearing member (825) adapted to engage the cephalad bearing member. The artificial caudal bearing member is adapted for a location lateral to the fixation point.
Abstract:
The invention discloses methods and devices for repairing, replacing and/or augmenting natural facet joint surfaces and/or facet capsules. A facet joint restoration device (410) of the invention for use in a restoring a facet joint surface comprises: a cephalad facet joint element comprising a flexible member (422) adapted to engage a first vertebrae and an artificial cephalad joint (426) ; and a caudad facet joint element comprising a connector adapted for fixation to a second vertebrae and an artificial caudad joint (428) adapted to engage the cephalad facet joint. In another embodiment, the invention discloses a facet joint replacement device for use in replacing all or a portion of a natural facet joint between a first vertebrae and a second vertebrae.
Abstract:
A decelerator comprising a deceleration tank and an extraction conveyor is disclosed. The decelerator is adapted for use with apples or similar objects. These objects are delivered to the tank from a pneumatic tube transport system. The tank contains a quantity of liquid such as water. In one embodiment, the objects splash into the water and are extracted from the water by an extraction conveyor. In a second embodiment, a baffle gate divides the tank between a forward section and a rear section. The delivered objects splash into the water in the forward section, travel under the baffle gate, and are extracted from the water by an extraction conveyor in communication with the rear tank section. In another embodiment, the tank is divided into first, second and third sections by selectively appeasable gate which provides an air lock arrangement. The extraction conveyor can comprise a plurality of side belts and a plurality of foraminous, flexible cradles hung between the belts.
Abstract:
An articulating intervertebral system for interposition between two vertebral endplates comprising: a first half (22) comprising upper and lower components (26,28) and a central body (38) adapted to articulate between the upper and lower components, and a second half (24) comprising upper and lower components and a central body adapted to articulate between the upper and lower components, wherein the first and second halves are adapted for implantation entirely within an intervertebral disc space between the two vertebral endplates .
Abstract:
Described is a locking mechanism and method of locking the relative positions of a fixation device (104) like a bone screw and of a stabilization device (106) like a rod. The locking mechanism includes a seat (102), a washer (108) and a cap (110). The seat (102) includes a bottom portion (114) configured to receive the fixation device (104) such that a socket (116) of the bottom portion (114) engages part of the fixation device (104) and prevents the fixation device (104) from passing entirely therethrough. The seat (102) further includes a side portion (112) configured to receive the stabilization device (106), a washer (108) and a cap (110). When the washer (108) and cap (110) are fully engaged with the seat (102), the fixation device (104) may be locked independent of the stabilization device (106). The locking mechanism may also include a locking element for locking the stabilization device (106).
Abstract:
An vertebral implant (20) is interposed between two vertebral endplates and comprises a first endplate assembly (22) having a first restraint mechanism extending from a first exterior surface (28) for engaging a first vertebral endplate The implant further comprises a second endplate assembly (24) having a second restraint mechanism (46) extending from a second exterior surface (30) for engaging a second vertebral endplate and a central body articulable between the first and second endplate assemblies. The first restraint mechanism has a shape that matches a contour in the first vertebral endplate.
Abstract:
A mobile system for improving the picking and preliminary processing of apples, citrus, stone fruit and the like is disclosed and claimed. The system comprises a mobile chassis upon which can be mounted picking stations, pneumatic tube transport subsystems, receiving and conveying subsystems, object scanning subsystems, cull diverter subsystems, labeling subsystems, and subsystems for relatively gently placing the objects in a predetermined location in a receiving bin. The system can also include a subsystem for gently placing diverted objects in a receiving bin.
Abstract:
The invention discloses devices, methods and systems for implanting articulating devices on the human spine. In some embodiments, three or more vertebrae are movable interconnected with artificial joints. Some embodiments are particularly well suited for implanting in the lumbosacral area of the spine. Some embodiments employ hybrid systems combining translaminar fixation with pedicular fixation of the device components. Some embodiments combine facet joint replacement with disc replacement.
