BRONCOSCOPE-COMPATIBLE CATHETER PROVIDED WITH ELECTROSURGICAL DEVICE

摘要

A catheter system can include an electrical adapter and a catheter. The electrical adapter includes a hollow adapter body having a longitudinally extending channel and an electrical terminal positioned within the channel. The electrical adapter can be configured to connect to an energy source. The catheter can include an elongated body having a proximal end portion and a distal end portion, and an electrical connector coupled to the proximal end portion. The electrical connector forms the outer periphery of the catheter along a portion of the longitudinal length of the catheter. The electrical terminal and the electrical connector contact each other when the electrical connector is advanced through the channel to an electrical contact position in the channel, and are isolated from each other when the electrical connector is proximal of the electrical contact position.
