Abstract

Pulmonary artery banding device (1) includes an inflating banding ring (2), to be installed around the patient's pulmonary artery (PA), an extending tube (3), and an insufflating button (4), the extending tube (3) connecting insufflating button (4) to the banding inflating ring, the banding ring being configured as a C-shape hydraulic sleeve forming a support for an inflating balloon, whose external wall (2a) is formed by a thin rigid silicon layer, and whose inside wall (2b) is formed by a thin flexible silicon layer, at the apart ends of the banding ring two brims being disposed (2c) to facilitate the size banding adjustment according with the pulmonary artery calibre (PA). The banding ring are provided with holes (2e) for passage of sutures fixating the ring on the pulmonary artery of the patient; the insufflating button being configured as a cylindrical reservoir and being provided with holes (4a) for sutures.
