Anterior spinal instrumentation and method for implantation and revision
InactiveUSRE37161E1Reliable and decompressionEnhanced rigidity and fixationInternal osteosythesisBone implantSpinal columnBone trephine
A system and method for anterior fixation of the spine utilizes a cylindrical implant engaged in the intradiscal space at the cephalad and caudal ends of the construct. The implants are cylindrical fusion devices (10) filled with bone material to promote bone ingrowth and fusion of the disc space. An attachment member (40) is connected to each of the fusion devices (10) and bone screws (30) having similar attachment members (33) are engaged in the vertebral bodies of the intermediate vertebrae. A spinal rod (50) is connected to each of the attachment members using an eyebolt assembly (53, 54, 55). In a further inventive method, a revision of the construct is achieved by removing the fusion devices. Each fusion device is engaged by an elongated guide member (62) over which a cylindrical trephine (70) is advanced. The trephine (70) has an inner diameter larger than the diameter of the fusion implant and includes cutting teeth (72) for extracting a core (84) of bone material around the fusion implant. The trephine (70) and guide member (62) are removed along with the bone core (84) containing the fusion implant (10). The trephine (70) is also used to extract a bone dowel from a solid bone mass to be inserted into the space left by the removed bone core (84).

Steerable spine implant and system
Embodiments of the invention being disclosed are directed to a spine implant that allows for in situ adjustment or steering during implantation which allows for precise placement. The structure of the device is composed of a series of hinged link components connected by dowel or shear pins allowing for the links to rotate with respect to each other. The steering feature of the device is activated by a series of tension members connected or coupled to the links. As the tension members are placed in tension, typically by pulling the appropriate member, forces are placed on the individual links to actuate / rotate them in a clockwise or counterclockwise direction. By controlling the rotation of the links, the device may be steered in the desired direction.

Magnetic tumble stirring method, devices and machines for mixing in vessels
InactiveUS6176609B1Corrosion resistanceGreat magnetic couplingBioreactor/fermenter combinationsBiological substance pretreatmentsMagnetic tension forceMicrowell Plate
The invention provides a simple method, device and several machines for simultaneously stirring thousands of vessels or wells of microplates in a robust manner and with economy. This method uses the simple principle of magnetic stirrers aligning themselves to a vertical driving magnetic field placed beneath them and moving laterally or by moving the vessels over a stationary magnetic field or by spinning the drive magnets, or by using a modulating / reversing electromagnetic field to produce the moving effect. Each vessel contains a magnetic disc, bar, dowel or other shape (stirrers) which in it's magnetic attraction to the vertical driving magnetic field will cause it to move and align it's magnetic field as the opposite poles of the drive magnet and the stirrer attract each other. The attraction of the stirrers to the vertical driving magnetic field causes the stirrers to stand on end and tumble as the stir devices try to align to the opposite moving magnetic pole. The stirrers tumble because the walls of the vessels or friction with the vessel bottom prevents their lateral movement.

Archers flame illuminated arrow nock
An archery arrow including conventional components such as a tubular shaft, a pointed head attached to the forward end of the shaft, fletching on the rearward portion of the shaft and a nock at the rear end of the shaft. The arrow structure also includes an illuminated nock of the present invention and includes a battery / switch / collar / L.E.D-combined unit, which is held in place by a single anchor pin with the L.E.D. portion of the battery inside a conventional translucent or clear nock. The arrow shaft also uses a wooden dowel or other like material to create a backstop and cushion within the arrow shaft. This may also be permanently constructed as part of the arrow shaft during manufacturing. This helps disperse the load generated from the strings forward motion when released from the bow in a full drawn position between the end cap and the entire battery and switch assembly. Upon shooting the arrow from a longbow, compound, or crossbow, the switch contacts are forced into the “closed switch” position by the forward force generated along the axis of the arrow shaft. Therefore, energizing the L.E.D. light source to give off light through the translucent or clear nock. Once shot and activated it's a simple matter of removing the nock from the shaft pulling rearward on the battery while holding the nock in a stationary position to turn the LED off. With this configuration of components said lighted nock can be dislodged from the arrow shaft and still remain in the lighted position. This invention is also reusable by turning said nock off and reinserting the nock back into the arrow shaft and shooting again. I have also made and tested a working prototype.
