  • Publication number: 20100274243
    Abstract: An elongated probe member is disclosed. The elongated probe member comprises proximal and distal ends, an outer wall, and a guidable region. The elongated probe member includes an internal lumen and a longitudinal axis defined therethrough. The guidable region is adjacent the distal end of the elongated probe member. The guidable region includes a plurality of undulating grooves.

  • Patent number: 7702397
    Abstract: A system and method for approaching the intervertebral disc through a percutaneous insertion from the back of a patient for thermal or electromagnetic treatment of an intervertebral disc, includes an elongated probe member having a guidable region adjacent its distal end with an undulating groove defined in its outer surface. The undulating groove is dimensioned to facilitate bending of the guidable region in at least one radial direction of movement relative to a longitudinal axis of the thermal probe. Preferably, the guidable region includes a plurality of undulating grooves, whereby adjacent undulating grooves are longitudinally spaced with respect to each other. The undulating grooves each define a sinusoidal configuration which may be arranged about an undulating axis extending in oblique relation to the longitudinal axis. The guidable region also includes a longitudinally extending backbone which resists bending of the guidable region in a radial direction of movement.

  • Publication number: 20070073284
    Abstract: A multiple RF return pad contact detection system is provided which is adaptive to different physiological characteristics of patients without being susceptible to electrosurgical current interference (e.g., interference or measurement interaction between components of the detection system). The detection system can measure or sense the contact resistance or impedance between the patient and pairs of RF return pads or return electrodes where multiple pairs of RF return pads are utilized due to the high current frequently needed during electrosurgery while eliminating or minimizing the risk of measurement interaction between the RF return pad pairs. The system allows for the independent and simultaneous measurement of the pad contact impedance for each pair of RF return pads. If the impedance of any pad pair is above a predetermined limit, the system turns off or reduces the electrosurgical output of the electrosurgical generator to prevent excess heating.

  • Publication number: 20060052848
    Abstract: A system and method for approaching the intervertebral disc through a percutaneous insertion from the back of a patient for thermal or electromagnetic treatment of an intervertebral disc, includes an elongated probe member having a guidable region adjacent its distal end with an undulating groove defined in its outer surface. The undulating groove is dimensioned to facilitate bending of the guidable region in at least one radial direction of movement relative to a longitudinal axis of the thermal probe. Preferably, the guidable region includes a plurality of undulating grooves, whereby adjacent undulating grooves are longitudinally spaced with respect to each other. The undulating grooves each define a sinusoidal configuration which may be arranged about an undulating axis extending in oblique relation to the longitudinal axis. The guidable region also includes a longitudinally extending backbone which resists bending of the guidable region in a radial direction of movement.
