Problems solved by technology

Fourth, many patients with heart failure have IVC filters due to increased propensity for deep vein thrombosis, which would prevent widespread use of IVC therapy
However, drug therapy has disadvantages such as cost and side effects

Embodiment Construction

[0088] refer to Figure 1A and 1B, describing the human anatomy in which the present invention is designed to fit and operate as a context for the systems and methods of the present invention.

[0089] More precisely, refer to Figure 1A , deoxygenated blood returns to the heart 10 through the vena cava 11 , which includes the superior vena cava 12 and inferior vena cava 13 connected to the right atrium 14 of the heart. Blood moves from the right atrium 14 through the tricuspid valve 15 to the right ventricle 16 where it is pumped to the lungs via the pulmonary artery 17 . Oxygenated blood returns from the lungs to the left atrium 18 via the pulmonary veins. The oxygenated blood then enters the left ventricle 19 which pumps the blood through the aorta 20 to the rest of the body.

[0090] Such as Figure 1B As shown in , the superior vena cava 12 is at the top of the vena cava 11 and the inferior vena cava 13 is at the bottom of the vena cava. Figure 1B Also shown is the a...

Abstract

Systems and methods and devices are provided for treating conditions such as heart failure and / or pulmonary hypertension by at least partially occluding flow through the superior vena cava for an interval spanning multiple cardiac cycles. A catheter with an occlusion device is provided along with a controller that actuates a drive mechanism to provide at least partial occlusion of the patient's superior vena cava, which reduces cardiac filling pressures, and induces a favorable shift in the patient's Frank-Starling curve towards healthy heart functionality and improved cardiac performance. Theocclusion device may include a lumen obstructed by a relief valve that may permit fluid flow through the occlusion device to release an excessive build-up of pressure.
