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. Darian, Dan Voic, Ronald R. Manna

Patent number: 7717913Abstract: A surgical instrument comprises, in accordance with the present invention, an elongate probe, a sleeve, a sleeve extension and at least one cauterization electrode. The probe is an ultrasonic element, serving to convey ultrasonic vibrations (as standing waves) to organic tissues at a surgical site. The probe has a working tip and a longitudinal axis. The sleeve surrounds the probe with the working tip of the probe projecting from a distal or free end of the sleeve. The sleeve extension is disposed at the distal or free end of the sleeve and defines a multiplicity of apertures having respective axes oriented at least substantially parallel to the longitudinal axis. The electrode has a distal or free end removably inserted through one of the apertures.Type: GrantFiled: November 4, 2004Date of Patent: May 18, 2010Assignee: Misonix, IncorporatedInventors: Theodore A. D. Novak, Alexander L. Darian, Dan Voic, Scott Isola

Patent number: 7442168Abstract: A tranducer assembly for an ultrasonic surgical instrument includes a front driver having an elongate shaft in one direction and a stud extending in an opposite direction. An electromechanical transducer element is disposed around the stud. The transducer assembly also comprises a rear driver disposed around the stud on a side of the electromechanical transducer element opposite the front driver, the electromechanical transducer element being clamped between the front driver and the rear driver. An inertial or damping mass is fixedly connected to the stud at a point spaced from the rear driver. The stud is of length and thinness to act as a flexible vibration damping element.Type: GrantFiled: April 1, 2003Date of Patent: October 28, 2008Assignee: Misonix, IncorporatedInventors: Theodore A.

Publication number: 20080058775Abstract: An ultrasonic medical probe has an elongate shaft with a head portion having a distal end face oriented at least partially transversely to a longitudinal axis of the shaft. The head portion has a lateral surface extending substantially parallel to the longitudinal axis, the lateral surface being provided with outwardly or radially extending projections. The shaft of the probe is provided with an internal longitudinal channel or bore and at least one ancillary or tributary channel communicating at an inner end with the longitudinal channel or bore and extending to the lateral surface. The ancillary or tributary channel has an outer end disposed in a region about the projections. The projections may be finely configured and distributed so as to form a knurled surface on the head portion.Type: ApplicationFiled: August 29, 2006Publication date: March 6, 2008Inventors: Alexander L.
