US 8,382,697 B2 · Devices, systems, and methods for peripheral arteriovenous fistula creation

Abstract

Devices, systems and methods are disclosed for the formation of an arteriovenous fistula in the limb of the patient. Embodiments include an apparatus for the creation, modification and maintenance of a fistula, including the modification of an existing dialysis fistula; and a method of supplying oxygenated blood to the venous circulation of a patient. A kit of anastomotic implants is described which supports a broad base of patient anatomies and fistula locations. The devices, systems and methods can be used to treat patients with one or more numerous ailments including chronic obstructive pulmonary disease, congestive heart failure, hypertension, hypotension, respiratory failure, pulmonary arterial hypertension, lung fibrosis and adult respiratory distress syndrome.

Dependent claims

A method of treating chronic obstructive pulmonary disease in a patient comprising:

externally visualizing anatomical structures in a limb of the patient to determine a degree of calcification;
selecting a first anatomical structure and a second anatomical structure in the limb based at least in part on the degree of calcification;
creating a fistula in the limb between a first anatomical structure and a second anatomical structure at a location based at least in part on the degree of calcification;
wherein the first anatomical structure contains blood at a first oxygen content level and the second anatomical structure contains blood at a second oxygen content level, said first oxygen content level greater than said second oxygen content level;
and
wherein the second anatomical structure provides blood to a lung of the patient.
