  • Publication number: 20130152757
    Abstract: Provided is a technique which can prevent abnormal vibrations from occurring on a resonator and apply, to a putting edge, vibrations with the magnitude of amplitude thereof adjusted in the direction of width of the edge, thereby cutting an object of interest with high accuracy. The resonator (21) with a grip portion grasped with clamp means (28) is supported by a support means (24), thereby preventing abnormal vibrations from occurring on the resonator (21). The resonator (21) has at least one elongated hole (26b) defined through a side thereof, thus allowing for adjusting the amplitude magnitude of vibrations in the direction of width of the cutting edge (23) on one end of the resonator (21). This enables vibrations with the amplitude of an adjusted magnitude in the direction of width to be applied to the cutting edge (23). Accordingly, the cutting edge (23) which is adequately vibrated can be used to cut the object of interest with high accuracy.

  • Patent number: 7128746
    Abstract: A method and device for treating human intervertebral disc herniations using an endoscopic procedure. An access port is opened into and through the annulus of a disc to remove nucleus pulposus. Subsequent treatment, a balloon device having a valve structure is positioned via an endoscopic procedure into the disc space. The balloon device is filled with a physiological fluid to occupy the disc interspace or to maintain some degree of distraction of the created disc space. Post surgery, after fibrocollagenous tissue has grown into the disc space, a second endoscopic procedure is performed to remove the balloon device. Fluid is removed to collapse the balloon structure and then removed via the guide tube. The ingrowth of fibrocollagenous tissue will continue to fill the void formerly occupied by the balloon device. The balloon device has a rigid valve body and a flexible balloon member. The valve body has an end plug, a valve chamber holding a valve member and a cooperating biasing structure.

  • Patent number: 6805715
    Abstract: A method and device for treating human intervertebral disc herniations using an endoscopic procedure. An access port is opened into and through the annulus of a disc to remove nucleus pulposus. Laser light fibers may then be passed through an endoscopic guide tube to anneal the inner surface of the disc annulus. Next, a balloon assembly with a valve is placed via the guide tube into the created disc space. The balloon is filled with a fluid to occupy the disc interspace or to maintain some degree of distraction of the created disc space. Post surgery, after fibrocollagenous tissue has grown into the disc space, a second endoscopic procedure is performed to remove the balloon assembly. Fluid is removed to collapse the balloon structure and then removed via the guide tube. The ingrowth of fibrocollagenous tissue will continue to fill the void formerly occupied by the balloon structure. The minimally invasive procedure of the invention allows for short term recovery and early return to normal activity.

  • Patent number: 6588432
    Abstract: A magnetic injection port assembly for a tissue expander system or similar inflatable medical device. The injection port assembly includes an injection port body having a cavity, a needle guard assembly, and a magnetic material therein. The needle guard assembly is positioned to prevent a hypodermic needle from passing through the medical device or interfering with the magnetic material. The magnetic material is affixed to the injection port body outside the cavity and the needle guard assembly. The magnetic material is spatially aligned with the region of the body into which the needle should be inserted so that this region may be located by locating the magnet with an external, non-invasive magnetic detection device.

  • Patent number: 6045553
    Abstract: A hybrid skull pin to adjust and hold a cervical fixation device to the skull of a patient. The hybrid skull pin is constructed of at least two different materials and arranged to permit cervical fixation devices to be used in MRI procedures. The hybrid skull pin has an elongated body with exterior threads and a tip portion for engaging the skull of the patient. A nonconductive coating extends over the tip portion of the skull pin body. The hybrid skull pin further includes an insert secured in the elongated body. The insert is constructed of a second material and secured in a cavity of the pin. The insert reduces the mass of the skull pin thereby reducing or eliminating the radio frequency energy conducted through the pin during MRI procedures. The insert also acts as a heat capacitor which absorbs the radio frequency energy and the magnetic field vibrations generated in the MRI environment.
