Renal denervation system

1. A system for use in a renal denervation procedure, comprising:

a) a catheter body having proximal and distal end portions, the distal end portion of the catheter body having a generally basket-shaped configuration that includes a pair of opposed arms joined at a distal tip section;

b) a sensor configured to sense at least one of an electrical or magnetic condition of one or more nerves of the renal artery via electromagnetic radiation given off by the nerve cell, the sensor positioned on a distal tip of the distal tip section of the distal end portion of the catheter body, wherein the sensor is electrically coupled to a sensing module through a first set of wires;

c) at least one electrode disposed on each arm of the pair of opposed arms of the distal end portion of the catheter body for delivering energy to renal tissue, wherein the electrodes are electrically coupled to one another in parallel through a second set of wires discrete from the first set of wires;

d) an actuating rod extending through the catheter body for transitioning the distal end portion of the catheter body between a linear shape and the generally basket-shaped configuration; and

e) at least one thermocouple is disposed on the distal end portion of the catheter body proximal to and discrete from the sensor for determining temperature at a desired location for regulating the plurality of electrodes during controlled ablation.

2. The system of claim 1 , further including a catheter handle at the proximal end portion of the catheter body, the catheter handle including means for connecting the catheter handle to a generator that is configured to provide energy to the at least one electrode disposed on each arm of the pair of opposed arms of the distal end portion of the catheter body for ablation of the renal artery.

3. The system of claim 2 , wherein the catheter handle includes a sliding switch connected to the actuating rod for moving the actuating rod within the catheter body.

4. The system of claim 2 , further comprising a generator operatively connected to the catheter handle to provide energy to the at least one electrode disposed on each arm of the pair of opposed arms for ablation of the renal artery.

5. The system of claim 4 , wherein the generator further includes the sensing module for receiving a signal from the sensor and determining a level of activity of the one or more nerves.

6. The system of claim 1 , wherein an overall diameter of the catheter body is less than 5F.

7. A system for use in a renal denervation procedure, comprising:

a) a catheter body having proximal and distal end portions, the distal end portion of the catheter body having a generally basket-shaped configuration that includes a pair of opposed arms joined at a distal tip section;

b) a sensor configured to sense at least one of electrical amplitudes, electrical fields, magnetic fields, or electric potentials of one or more nerves of the renal artery, the sensor positioned on a distal tip of the distal tip section of the distal end portion of the catheter body, wherein the sensor is electrically coupled to a sensing module through a first set of wires;

c) at least one electrode disposed on each arm of the pair of opposed arms of the distal end portion of the catheter body for delivering energy to renal tissue, wherein the electrodes are electrically coupled to one another in parallel through a second set of wires discrete from the first set of wires;

d) an actuating rod extending through the catheter body for transitioning the distal end portion of the catheter body between a linear shape and the generally basket-shaped configuration; and

e) at least one thermocouple disposed on the distal end portion of the catheter body proximal to and discrete from the sensor for determining temperature at a desired location for regulating the plurality of electrodes during controlled ablation.
