Benefits of technology

The present invention is about treating heart failure and pulmonary hypertension by increasing the flexibility of the pulmonary arterial vasculature. Various devices and methods are disclosed for achieving this, including the implantation of a flexible element in the pulmonary arterial trunk and other vessels. The invention also includes providing a means for adjusting the amount of flexibility and repositioning or removing the implant as needed. Overall, the invention improves the function and symptoms of patients with right heart failure and pulmonary hypertension.

Problems solved by technology

Right-sided and left-sided heart failure can both lead to pulmonary hypertension which can in-turn lead to right heart failure.

Abstract

Devices and methods for increasing a patient's pulmonary arterial compliance are disclosed. The devices include catheters designed to create a connection between a patient's venous anatomy and the patient's pulmonary artery. With the arteriovenous connection various devices can be implanted in order to increase the volumetric compliance of the pulmonary artery. The devices include collapsible and expandable mechanisms which allow the effective pulmonary arterial volume to expand during systole and contract during diastole. The devices may include a balloon or balloon-like implants which cyclically shuttle a working fluid from the pulmonary artery to the vein and back. The devices may be adjustable to provide desired hemodynamic benefits. Methods are disclosed for making and using the inventive devices.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority to and the benefit of U.S. Provisional Application No. 62 / 735,623, entitled “Pulmonary Arterial Compliance Enhancement and Control Device,” filed on Sep. 24, 2018, which is incorporated herein in its entirety by reference.FIELD OF THE INVENTION[0002]The present invention relates to methods and devices for pulmonary hypertension and heart failure. In particular, the present invention relates to methods and devices for treating pulmonary hypertension by increasing the pulmonary arterial compliance and thereby reducing the right ventricle after-load.BACKGROUND[0003]Heart failure is a condition effecting millions of people worldwide. Right-sided and left-sided heart failure can both lead to pulmonary hypertension which can in-turn lead to right heart failure. There exists a need for devices and methods for treating pulmonary arterial hypertension and right heart failure. Pulmonary arterial hypertension is descr...
