Abstract

Described here are devices and methods for treating hypertension by forming a fistula between two blood vessels to reduce blood pressure of a patient. The fistula may be formed using a catheter having an electrode that is placed in a first blood vessel. In some instances, a desired amount of blood pressure is determined. In other instances, the hypertension is drug resistant hypertension.

Claims

1. A method of treating a patient having hypertension comprising:

advancing a first catheter into a first deep ulnar vein and a second catheter into an artery, wherein the first catheter comprises an electrode, the first deep ulnar vein being substantially parallel to a proximal ulnar artery between a brachial artery and an interosseous artery; and

forming a first fistula between the first deep ulnar vein and the artery with the electrode to reduce a blood pressure of the patient.

2. The method of claim 1 further comprising determining a desired amount of blood pressure reduction, and forming the first fistula based on the desired amount of blood pressure reduction.

3. The method of claim 1 wherein the artery is the proximal ulnar artery.

4. The method of claim 1 further comprising forming a second fistula between the artery and a second deep ulnar vein.

5. A method of treating a patient having hypertension comprising:

advancing a first catheter into a first deep ulnar vein and a second catheter into an artery, wherein the first catheter comprises an electrode, the first deep ulnar vein being substantially parallel to a proximal ulnar artery between a brachial artery and an interosseous artery;

forming a fistula between the first deep ulnar vein and the artery with the electrode, wherein the fistula is configured to reduce blood pressure of the patient below a desired blood pressure; and

modifying one or more of the first deep ulnar vein and the artery to increase the blood pressure to the desired blood pressure.
