1. A catheter system comprising:

  • an electrical adapter including a hollow adapter body having a longitudinally extending channel and an electrical terminal positioned within the longitudinally extending channel, the electrical adapter being configured to be electrically connected to an energy source; and

    a catheter having a longitudinal length and being removeably insertable within the electrical adapter, the catheter including an elongated body having a proximal end portion and a distal end portion, the distal end portion defining a first diameter and including an electrosurgical cutting tip, the distal end portion being configured to be inserted into a proximal most end of the longitudinally extending channel and advanced through an entirety of the longitudinally extending channel during an electrosurgical procedure; and

    an electrical connector coupled to the proximal end portion of the elongated body, the electrical connector forming an outer periphery of the catheter along a portion of the longitudinal length of the catheter, the electrical connector defining a second diameter larger than the first diameter, the electrical connector configured to be inserted in the channel of the hollow adapter body, wherein the electrical terminal and the electrical connector are configured to be electrically connected to each other when the electrical connector is advanced to an electrical contact position within the channel, and are configured to be electrically isolated from each other when the electrical connector is proximal of the electrical contact position.
