Described here are methods of treating a patient having hypertension comprising advancing a catheter into a deep ulnar vein or an artery, wherein the catheter comprises an electrode. The methods further comprise forming a fistula between the deep ulnar vein and the artery with the electrode to reduce a blood pressure of the patient.

Methods for treating hypertension and reducing blood pressure with formation of fistula

Described here are devices, systems and methods for forming a fistula between two blood vessels. Generally, the systems may comprise a first catheter which may comprise a fistula-forming element. The fistula-forming element may comprise one or more electrodes, mechanical cutting elements, laser sources, or combinations thereof, and may be used to assist in fistula formation. In some instances, a system may comprise a second catheter, which may comprise a fistula-forming element. One or more of the catheters may comprise one or more markers, magnetic alignment elements, and/or one shape-changing elements.

Devices and methods for forming a fistula

Described here are devices, systems, and methods for forming a fistula between two blood vessels. The systems may comprise a first catheter including a housing and an electrode having a proximal end and a distal end. The proximal end is fixed relative to the housing and the distal end is longitudinally slidable within the housing.

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.

Described here are devices and methods for forming a fistula between two vessels. In some instances, the fistula may be formed between a proximal ulnar artery and a deep ulnar vein. The fistula may be formed using an electrode, and may be formed with a first catheter placed in a first blood vessel and a second catheter placed in a second blood vessel. In some instances, access to the proximal ulnar artery may be achieved through a brachial artery, and access to the deep ulnar vein may be achieved through a brachial vein.
