Abstract: Methods are disclosed for the formation of arterio-venous fistula creation. Embodiments include a femoral access approach to the creation of an Aorta-caval fistula at the bifurcation of the Aorta and the Inferior Vena Cava; an apparatus for the creation, modification and maintenance of a fistula; and a method of supplying oxygenated blood to the venous circulation of a patient. 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.

Abstract: A method for treatment of COPD, hypertension, and left ventricular hypertrophy, and chronic hypoxia including creation of an artificial arterio-venous fistula and installation of a flow mediating device proximate the fistula. The flow mediating device is operated to limit flow as medically indicated to provide the optimum amount of bypass flow.

Abstract: A shunt rivet for implementation in the aorta and inferior vena cava to treat chronic obstructive pulmonary disease, and a method of treating chronic obstructive pulmonary disease.

Abstract: Devices, systems and methods are described for visualizing the anatomy of a patient. An expanding portion is configured to expand towards the tissue walls of a body space and be visible with one or more visualization instruments. Systems and methods are described which advance a probe from a first vessel toward a target in a second vessel.

Abstract: Methods are disclosed for the providing oxygenated blood to venous circulation. Embodiments include a femoral access approach to the creation of an Aorta-caval fistula at the bifurcation of the Aorta and the Inferior Vena Cava; an apparatus for the creation, modification and maintenance of a fistula; and a method of supplying oxygenated blood to the venous circulation of a patient. 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.

Abstract: A long-term implantable arterio-venous shunt device or creation of a fistula is provided that can be used as a therapeutic method for treating chronic obstructive pulmonary disease (COPD). The shunt device is implanted between an artery and a vein, preferably between a peripheral artery and the inferior vena cava. The shunt device and method of creating a fistula increases cardiac output and decreases the systemic vascular resistance and allows a blood flow rate through the shunt device of at least 5 ml/min after the implantation. Based on the effects of the method and device to the respiratory, cardiac and circulatory system, the method and device are beneficial as a therapy to patients with problems or conditions related to these systems.

Abstract: A shunt rivet for implantation between a first body space and a second body space in a patient, such as to treat chronic obstructive pulmonary disease.

Abstract: Methods are described for screening patients suffering from compromised cardiopulmonary function to determine if they will benefit from arteriovenous fistula therapy. Performance of an exercise regimen by the patients both in the presence and absence of supplemental oxygen is measured. Those patients whose performance improves in the presence of supplemental oxygen are considered likely candidates for benefitting from arteriovenous therapy.

Abstract: A long-term implantable arterio-venous shunt device is provided that can be used as a therapeutic method. The shunt device is implanted between an artery and a vein, preferably between the aorta and the inferior vena cava. The shunt device decreases the systemic vascular resistance and allows a blood flow rate through the shunt device of at least 5 ml/min after the implantation. The blood flow rate could be controlled either via an open loop or a closed loop control means. The shunt device could also be a self-adjustable shunt device to self-adjust its structure to control the blood flow rate through its lumen. Based on the effects of the shunt device to the respiratory, cardiac and circulatory system, the implantable shunt device could be beneficial as a therapy to patients with problems or conditions related to these systems.

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.

Abstract: Devices, systems and methods are disclosed for the formation of an arteriovenous fistula in the limb of the patient. Embodiments include a device for the creation, modification and maintenance of a fistula that includes an integral fistula creation assembly near its distal end that passes through the skin of the patient, through a first vessel such as an artery, and into a second vessel such as a vein. The fistula creation assembly preferably includes an anastomotic implant that is placed within the fistula to maintain long-term blood flow therethrough. 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.
