    Abstract: An electrosurgical electrode assembly having a cutting device including a catheter with a proximal and distal end, and an electrode carried on the distal end of the catheter. A controller is connected to the cutting device. A data acquisition system is connected to the controller and is capable of monitoring voltage and current output. A microprocessor may also be connecte d to the data acquisition system for processing voltage and current data from the data acquisition system. A generator is also connected to the data acquisition system. The controller initiates movement of the electrode upon arc initiation at the electrode. Methods of using the devices herein are als o disclosed.

    Abstract: A tissue-separating catheter assembly comprises a rotatable shaft, having a distal shaft portion, and a tissue separator device extending along the shaft. The tissue separator device has a distal separator part at the distal shaft portion movable between a retracted state, towards the distal shaft portion, and an outwardly extending, operational state, away from the distal shaft portion. A pivot joint may be used to pivotally connect the distal separator end to the distal shaft portion. The distal shaft portion may comprise a distally-facing transition surface at a proximal end of the distal shaft portion. First and second energizable tissue separator elements may be used at the transition surface and the tip of the device, respectively.

    Abstract: A tissue-separating catheter assembly comprises a rotatable shaft, having a distal shaft portion, and a tissue separator device extending along the shaft. The tissue separator device has a distal separator part at the distal shaft portion movable between a retracted state, towards the distal shaft portion, and an outwardly extending, operational state, away from the distal shaft portion. A localization device is movable to a radially expanded state. An expandable tubular element is movable so that its outer end is generally axially aligned with the localization device so to capture a separated tissue section therebetween to aid removal of the separated tissue section from the patient.

    Abstract: A tissue separator assembly 10 includes a proximal end assembly, typically a handle 14, and a catheter assembly12, including a shaft 44 and a tissue seperator 56 movable between a retracted state and an outwardly extending, operational state. An energy source 24 may be selectively coupled to the tissue separator element 56. The tissue separator element 56 may be moved to the operational state and then automatically rotated to separate a tissue section from the surrounding tissue. A tissue holding element 104 may be used to help secure a separated tissue section to the catheter assembly.12. A tubular braided element 104 may be used to surround the tissue separator element 56 and any separated tissue section.
