摘要： An electrosurgical forceps is provided. The electrosurgical forceps includes a housing having a shaft extending distally therefrom. The shaft defines a longitudinal axis therethrough and a knife blade shaft is operably disposed within the shaft. An end effector is operably disposed at a distal end of the shaft. The end effector includes a pair of spaced-apart first and second jaw members that are movable from an open configuration to a clamping configuration. An electrode assembly includes first and second electrode housings and a knife blade. The first and second electrode housings are operably coupled to one another and are configured to selectively couple to respective first and second jaw members to electrosurgically treat tissue clamped between the first and second jaw members. The knife blade is configured to selectively couple to the knife blade shaft.

摘要： A catheter includes an outer tubular body, a spiral member, and a disruptor. The outer tubular body defines a longitudinal axis and extends to a distal annular cutting edge. The outer tubular body defines a lumen having distal and proximal ends. The spiral member is supported within the outer tubular body and includes proximal and distal ends. The distal end of the spiral member is positionable distally beyond the cutting edge of the outer tubular body. The disruptor is supported within the outer tubular body proximally of the cutting edge of the outer tubular body.
