Abstract
Systems and methods for monitoring and performing tissue modulation are disclosed. An example system may include an elongate shaft having a distal end region and a proximal end and having at least two nerve modulation elements disposed adjacent to the distal end region. The nerve modulation elements may be used to determine and monitor changes in tissue adjacent to the modulation element and to effect tissue changes.
Claims20
An intravascular nerve modulation system comprising:
- an elongate shaft having a proximal end region and a distal end region;
- a first nerve modulation element disposed adjacent the distal end region;
- a second nerve modulation element disposed adjacent to the first nerve modulation element;
- wherein the first and second nerve modulation elements are configured to monitor impedance of a surrounding region and ablate the surrounding region.

A method for detecting tissue changes during tissue modulation, the method comprising:
- providing a tissue modulation system comprising:
- an elongate shaft having a proximal end region and a distal end region;
- a split plate electrode disposed adjacent to the distal end region of the elongate shaft, the split plate electrode including a first electrode plate and a second electrode plate spaced a distance from the first electrode plate;
