<p>The invention relates to an intracardiac device which is used to create a total cavopulmonary anastomosis by catheterisation. The inventive device consists of a curved tubular mesh conduit comprising metal wires, which is at least partially covered with a polymer that is impermeable to the passage of blood. According to the invention, the aforementioned tube comprises a lower portion (1) and an upper portion (2). The upper portion (2) is divided into two branches such as to form a deformed Y shape comprising: a larger branch (6) which is housed inside the left pulmonary artery, and a second smaller branch (7) in the form of a small backward-projecting segment which is introduced into the beginning of the right pulmonary artery. The lower portion (1) comprises a lower end (1a) which is connected to the inferior vena cava and the suprahepatic veins. The device is housed inside the right auricula of the heart. Moreover, at least one opening is located on one side of the above-mentioned lower portion (1), said opening defining a selectively-sealable fenestration (5) which communicates the interior of the tubular conduit with the exterior of same.</p> |
