摘要: Several unique intracardiac pressure vents, placement catheters, methods of placement and methods of treating heart failure are presented. The intracardiac pressure vents presented allow sufficient flow from the left atrium to the right atrium to relieve elevated left atrial pressure and resulting patient symptoms. In an aspect of the invention, the interatrial device comprises portions that are more flexible or less flexible than another portion of the device.

摘要: A method and devices for relieving pressure in the left atrium of a patient's heart is disclosed. The method includes using an ablative catheter in a minimally invasive procedure to prepare an opening from the coronary sinus into a left atrium of the patient's heart. Once the opening is prepared, the opening may be enlarged by a technique such as expanding a balloon within the opening. A stent is then placed within the coronary sinus of the patient, with a transverse portion expanding within the opening, allowing blood to flow from the left atrium to the coronary sinus and then to the right atrium. Pressure within the left atrium is thus relieved.

摘要: The present disclosure relates to devices and methods for implanting a prosthesis into a heart of a mammal, such as a person. The disclosure includes a prosthesis that acts as a pressure vent between the left and right atria of the heart. The disclosure also includes a mounting tool for mounting the prosthesis onto a loading tool, the loading tool useful for loading the prosthesis onto a device for delivering the prosthesis into the patient's heart. Control devices and methods for using these devices are also disclosed. The intracardiac pressure vents disclosed allow sufficient flow from the left atrium to the right atrium to relieve elevated left atrial pressure and resulting patient symptoms. The devices also limit the amount of flow from the right atrium to the left atrium to minimize the potential for thrombi or other embolic material from entering arterial circulation.

Retrievability during deployment is improved, in part, by providing at least one segment or portion of the device that is retained within the placement catheter while all other segments or portions of the device are deployed.
