Abstract

Medical devices and methods for making and using medical devices are disclosed. An example medical device may include a renal nerve modulation device. The renal nerve modulation device may include an elongate shaft. A balloon may be coupled to the shaft. The balloon may have a hydrophilic electrode region. A sensor may be coupled to the balloon and may be disposed adjacent to the hydrophilic electrode region. An electrode may be coupled to the catheter shaft and may be disposed within the balloon.

Claims

1. A nerve modulation device, comprising:

an elongate catheter shaft;

a balloon coupled to the shaft, the balloon having a plurality of hydrophilic electrode regions defined thereon;

a plurality of flexible sensors coupled to the balloon, wherein at least one of the plurality of flexible sensors is disposed at an interior surface or an exterior surface of the balloon adjacent to each of the hydrophilic electrode regions;

a conductive fluid disposed within the balloon;

a radiofrequency electrode disposed within the balloon; and

wherein the conductive fluid is configured to conduct radiofrequency energy from the radiofrequency electrode to the hydrophilic electrode regions.

2. The nerve modulation device of claim 1, wherein the balloon includes an inner layer and an outer layer.

3. The nerve modulation device of claim 2, wherein the hydrophilic electrode region is defined by the absence of the outer layer along a portion of the balloon.

4. The nerve modulation device of claim 3, further comprising an additional sensor disposed adjacent to the each of the hydrophilic electrode regions.

5. The nerve modulation device of claim 1, wherein the sensor includes a temperature sensor.

6. The nerve modulation device of claim 1, wherein the sensor includes a pressure sensor.
