摘要：
Provided herein are systems, methods, and apparatus for electroporation, which may include an applicator； an endoscope, trocar or the like； a generator； and a drug delivery device. The applicator may include a control portion, an insertion tube connected to the control portion, an actuator engaged with the control portion, and a plurality of electrodes comprising a first electrode having a first tip and a second electrode having a second tip. The plurality electrodes may be configured to move between a retracted position and a deployed position in response to actuation by the actuator. A distance between the first tip of the first electrode and the second tip of the second electrode may be greater in the deployed position than in the retracted position. Various treatment methods are also provided.
