  • Patent number: 8753394
    Abstract: A method and apparatus are provided to manipulate and revitalize a spinal column disc while minimizing or preventing the removal of material comprising the disc. The method allows a device to be inserted in the disc either through a pre-existing rupture or through an opening formed in the front, back, or sides of the disc. Increasing the space between the vertebra bounding the disc or removing disc material often is not necessary to insert the device in the disc. The device generates internal traction or other forces acting on the disc to alter the shape of the disc. The shape of the disc is altered to relieve pressure on nerves adjacent the disc. The shape of the disc is also altered to draw nuclear hernias back into the interior of the disc and to produce a disc shape that improves functioning of the disc.

  • Patent number: 6389226
    Abstract: A compact tankless water heater of modular configuration to accommodate a range of potential demands is disclosed. A heat transfer chamber is divided into subchambers, each of which may may mount more than one heating element. Notched passageways at the top of each dividing wall allow water passage between chambers, and a plurality of temperature sensors act in concert with a flow sensor and microprocessor control of the heating elements to maintain a constant set point output water temperature.
