A method and apparatus are disclosed for an RF guidewire for applying RF energy to create a channel through a region of tissue within a patient's body. The RF guidewire is configured to have a hydrophilic coating disposed thereon to reduce friction to facilitate traversal through vasculature while maintaining its mechanical, electrical and thermal properties.

Electrosurgical device for creating a channel through a region of tissue and methods of use thereof

An electrosurgical device and methods are disclosed for creating a channel through a region of tissue. The device comprises an elongate member for receiving the energy from an electrical energy source. An electrical insulation layer surrounds the elongate member along the device proximal region. An electrode tip is coupled to the distal end of the elongate member for delivering the energy, the electrode tip being configured and sized for delivering the energy in a manner such that electrical arcing is generated in the region of tissue in order to create a channel through at least a portion of the region of tissue. An electrically insulative thermal shield is disposed between the electrode tip and the device proximal region for preventing arcing therebetween during the delivery of the energy and for thermally protecting the device proximal region from heat produced by the delivery of the energy through the electrode tip.

An energy delivery apparatus for delivering electrical energy at a target location, the energy delivery apparatus being usable in combination with a magnetic field. The energy delivery apparatus includes an electrical conductor, the electrical conductor having a substantially elongated configuration; an electrode for delivering the electrical energy at the target location, the electrode being electrically coupled to the electrical conductor and located at a predetermined location therealong; and a guiding element mounted to the electrical conductor in a substantially spaced apart relationship relative to the electrode, the guiding element including a magnetically responsive material. The energy delivery apparatus is constructed such that a movement of the guiding element causes a corresponding movement of the electrode. The magnetic field is used to move the guiding element in order to position the electrode substantially adjacent to the target location.
