摘要： The present disclosure relates to a method and a device for treating heart failure by normalizing elevated blood pressure in the left and right atria of a heart of a mammal. The present disclosure includes methods for creating and maintaining an opening in the atrial septum. Tools for making an opening and enlarging the opening are also disclosed. Use of the techniques and tools described herein prolongs the patency of an intra-atrial pressure relief opening.

摘要： Devices and methods to enhance the implantation, retrievability, or repositionability are provided. Embodiments of devices include pivotable sections providing the ability to maintain the device's engagement with a delivery system during implantation where the deliver system approaches an opening of the septum at an angle. Embodiments of devices also include configurations that allow for improved retrieval into a delivery system in the event that a malfunction or a problem with the patients physiology is detected.

摘要： Several unique intra-cardiac pressure devices, placement catheters, methods of placement and methods of treating heart failure are presented. The intra-cardiac pressure devices presented allow sufficient flow from the left atrium to the right atrium to enable the relief of elevated left atrial pressure and resulting patient symptoms. The intra-cardiac pressure devices are made of a non-braided material.
