  • 10. 
    What is the origin and definition of the word COBLATION?
    • A. 

      Controlled ablation - A heat-driven process using bipolar RF energy in conjunction with a conductive medium, such as saline, to create a highly focused plasma layer with high current dissipation resulting in tissue removal.

    • B. 

      Controlled ablation - A chemical etching process using bipolar RF energy in conjunction with a conductive medium, such as saline, to create a highly focused plasma layer that contains energy sufficient to break the molecular bonds within tissue. This provides precise, volumetric tissue removal.

    • C. 

      Controlled ablation - A non-heat driven process using monopolar radiofrequency energy in conjunction with a non-conductive medium to create a large plasma layer between the tip of the Wand and the tissue to break the molecular bonds resulting in tissue removal.

  • 11.

    • A. 

      True

    • B. 

      False
