Abstract: The present invention comprises devices, systems, and methods for elongating bone using an extension implant having a first end and a second end. The first end of the extension implant is inserted into an opening in the live bone and the second end of the extension implant is combined with an enlarged implant. A plurality of channels extend through the components to serve as conduits for delivering fluids and physiological signals which induce bone formation. Some embodiments include a subcutaneous cage assembly for helping to support the implant as the bone heals around it.

Abstract: Methods, devices and systems are disclosed for chemically bonding antibiotics to selected substrate materials which are not dissolved in normal physiological processes so that high local concentrations can be achieved during the inflammatory response. The antibiotics will remain permanently bonded to the substrate material until an infection occurs which releases the antibiotic in high concentrations to help control the infection. The high local concentrations may be much higher than systemic toxic levels, and can never reach toxic levels because the local dose is much less than needed to reach systemic toxicity if completely dissolved.

Abstract: Apparatuses, systems, and methods for enhancing bone or soft tissue regeneration are provided. For example, a conduit, having one or more segments, can originate at a tissue regeneration site and can have a first opening to promote physiological signals to enter the conduit and transit to a second opening that penetrates a histologically rich source of multipotent mesenchymal cells, promoting the multipotent mesenchymal cells to produce tissue regeneration response products, the response products transiting through the second opening to egress at the first opening of the conduit, and promoting tissue regeneration at the tissue regeneration site. Transit of the physiological signals and the tissue regeneration response products is promoted through physical and/or chemical means, as is promotion of the anatomical functionality of the regenerated tissue. For example, a number of the segments of the conduit can be formed at least partially from an osteoceramic material.

Abstract: This invention provides orthopedic cement compositions, containing calcium phosphate component, an anion-donating accelerator to promote rapid setting, and a calcium aluminate component. Further provided are methods for orthopedic repair, including placing the cement at said surgical site by applying low shearing force to said cement to initiate flow.

Abstract: A method of producing reconstructed bone. The method includes providing an implant structure having a calcium phosphate component, and stabilizing the implant adjacent the healthy bone until tissue can recover, bond to the implant and support the normal required loading. The implant structure provides morphological continuity and anatomical contact between the implant body and the adjacent healthy bone. The method further includes providing for physiological processes to maintain a healthy junction between the implant and the healthy bone. The method further includes controlling, guiding and directing the bone reconstruction process in surgical situations where healthy recovery would not otherwise occur.

Abstract: A heat transfer sensing apparatus for opening window drapes and blinds determines whether the net heat flux is positive or negative. The apparatus includes first and second temperature sensing devices which are mounted adjacent a window. Both of the devices are exposed to the convective heat transfer conditions within the room, and the first temperature sensing device can be heated or cooled by radiant energy through the window. A shield shields the second temperature sensing device from direct radiant heat transfer to the window. A signal generator device connected to the temperature sensing devices generates a signal depending upon the difference in temperature of the temperature sensing devices, and the drapes are opened or closed according.

Abstract: Dense mullite ceramic bodies are manufactured from a mullite-proportioned mixture of alumina (Al.sub.2 O.sub.3) and silica (SiO.sub.2) containing a critically small amount of titania (TiO.sub.2). The preferred concentration of titania based on the mullite (Al.sub.6 Si.sub.2 O.sub.13) is from 0.5 to 1.0% by weight, which by means of a specific sequence of processing steps results in mullite bodies having densities of 2.5 g./cc. or greater. More specifically, a molecularly intermixed mixture is calcined at a temperature of 900 to 1150.degree. C. to convert the mixture to mullite in intimate association with the small percentage of titania, which is present essentially as fine titania crystals. The calcined mullite is ground to break up the aggregates and obtain a mixture of essentially discrete crystals of mullite and titania. The ground mixture is formed into the shape of the desired bodies, and the bodies are heated at an effective sintering temperature to produce the dense mullite bodies.

Abstract: This invention relates to a method of compressing ceramic refractory bodies which can be designated as "hot forging", as distinguished from "hot pressing", although both processes involve the compressing of formed porous bodies of ceramic refractory material to decrease their porosity and increase their strength. The hot forging process utilizes a breakaway mold having cooled die members. The porous ceramic body has been prepared for the compression by being heated to a pyroplastic temperature (viz. 1100.degree.-1500.degree. C.). It is rapidly compressed within the cold mold, a temperature gradient of the order of 1000.degree. C. being maintained from the cooled inner die surfaces to a depth of not over 5 milliliters into the body from the die-contacted outer surfaces. While a thin porous skin is formed around the body, its thickness is limited to not over the depth of the temperature gradient.
