Catheters and methods for endovascular treatment with electrodes

A method of forming a catheter comprising at least two electrodes, comprising:

• bending the at least two electrodes of the catheter such that the at least two electrodes are shaped to extend away from a centerline of a catheter body of the catheter,
• wherein the catheter body includes a sidewall defining an opening, the at least two electrodes include ablation surfaces, extend through the opening, and intersect one another at one or more locations to define a cutting shape when in a deployed configuration.

A catheter for endovascular treatment comprising:

• a catheter body comprising a sidewall with an opening formed in the sidewall;
• and
• an electrode comprising an ablation surface, the ablation surface having an ablation opening such that the ablation surface splits and joins to define a cutting shape when in a deployed configuration.
