Abstract
An electrosurgical system for puncturing tissue includes an electrosurgical generator configured to generate radiofrequency (RF) energy, and a crossing device connected to the electrosurgical generator, the crossing device including an electrode with a plurality of bores that extend into an exterior surface of the electrode. The electrode may be positioned at a distal tip of the crossing device.
Claims20
An electrosurgical system for puncturing tissue, the electrosurgical system comprising:
- an electrosurgical generator configured to generate radiofrequency (RF) energy;
- and
- a crossing device connected to the electrosurgical generator, the crossing device including an electrode with a hollow cavity and a plurality of bores that extend from the hollow cavity through an exterior surface of the electrode.
An electrosurgical system for puncturing tissue, the electrosurgical system comprising:
- an electrosurgical generator configured to generate radiofrequency (RF) energy;
- and
- a crossing system comprising:
- a steerable sheath;
- a dilator slidably positioned in the steerable sheath;
- and
- a crossing device slidably positioned in the dilator and electrically connected to the electrosurgical generator, device connected to the electrosurgical generator, the crossing device including an electrode with a plurality of bores that extend into an exterior surface of the electrode.
A method of operating an electrosurgical system, the method comprising:
- positioning a crossing member, wherein the crossing member includes a crossing device including an electrode with a plurality of bores that extend into an exterior surface of the electrode;
- energizing an electrode of the crossing device using an electrosurgical generator;
- forming and coalescing gaseous bubbles on the electrode;
- and
- vaporizing tissue with the energized electrode.
