Patent number: 9070856Abstract: An electrical waveform generator for driving an electromechanical load includes a digital signal processor connected to a waveform generator component in turn connected to an amplifier section with a filter network, the latter being connected to sensing and conditioning circuit componentry that is in turn connected to analog-to-digital converter circuitry. A digital memory stores digitized voltage and current waveform information. The processor determines a phase difference between voltage and current waveforms, compares the determined phase difference to a phase difference command and generates a phase error or correction signal. The processor also generates an amplitude error signal for inducing the amplifier section to change its output amplitude to result in a predetermined amplitude error level for a respective one of the voltage and current waveforms.Type: GrantFiled: June 28, 2013Date of Patent: June 30, 2015Assignee: MISONIX, INCORPORATEDInventors: Emery Rose, Ronald R.

Patent number: 8353912Abstract: In a discectomy method one removes at least a substantial portion of a spinal disc. Thereafter one operates an ultrasonic instrument to level opposing faces of vertebrae on opposite sides of the removed spinal disc. Graft or synthetic disc material is inserted between the vertebrae so that the graft or synthetic disc material is in contact with the leveled opposing faces. In an associated nucleotomy, a cannulated probe is inserted into a spinal disc and used to remove the nucleus pulposus. A synthetic or substitute nucleus material may then be inserted into the evacuated annulus.Type: GrantFiled: June 1, 2007Date of Patent: January 15, 2013Assignee: Misonix, IncorporatedInventors: Alexander L.
