Publication number: 20060265026Abstract: Osteogenesis and osseointegration promotion and maintenance devices for osseous implants include an implant member having a first electrode, an inlaid second electrode positioned on the member so that it is electrically isolated from and substantially flush with the member surface, and an electrical stimulation mechanism preferably located at the member and operative to provide electrical stimulation signals to endosseous tissue surrounding the implant through the first and second electrodes. The first electrode may be the member itself or a second inlaid electrode. The implant is thus electrically functionalized for osteogenesis and osseointgration acceleration. The device is applicable to both non-dental and dental implants. In all embodiments, the use of inlaid electrode(s) enables the general appearance, external surface and mechanical integrity of the implant to be left essentially unchanged.Type: ApplicationFiled: January 29, 2004Publication date: November 23, 2006Inventors: David Madjar, Menachem Nathan, Emanuel Peled, Hanan Terkel

Patent number: 5680073Abstract: A controlled capacitor system, which includes a capacitor element (C1) and a forward-biased diode element (D2) connected in series with the capacitor element (C1). The system is such that the diode element (D2) has a capacitance which is less than the capacitance of the capacitance of the capacitor element (C1) when the diode element (D2) is under zero bias. The capacitance of the diode element (D2) is controlled by varying the forward current (I2) through the diode (D2). The forward current (I2) acting to control the capacitance of the diode element is selected such that the capacitance of the diode element (D2) is smaller than the capacitance of the capacitor element (C1) when the current (I2) through the diode element (D2) is below a minimum value. The capacitance of the diode element (D2) is bigger than the capacitance of the capacitor element (C1) when the current (I2) through the diode element (D2) exceeds a maximum value.Type: GrantFiled: February 6, 1995Date of Patent: October 21, 1997Assignee: Ramot University Authority for Applied Research & Industrial Development Ltd.Inventors: Menachem Nathan, Leonid Zolotarevski, Olga Zolotarevski, German Ashkinazi, Boris Meyler
