ABSTRACT:
The present invention discloses a connecting device to connect artificial arteries to normal arteries. The object of the invention is the prevention of obstruction of blood flow by hypertrophy of the inner lining of the artery commonly designated as the intima. The connecting device is placing the opening of the artificial artery inside of the natural artery beyond the level of the intima. This arrangement is preventing irritation of the intima of the natural artery by reducing turbulence of the boundary layer of the flowing blood. The connecting device can be manufactured as an integral part of the artificial artery or as a separate part to be connected to an artificial artery. The connecting device consists of a part penetrating the wall of the tapped natural artery and a sleeve to be attached to the outside of the natural artery. The sleeve itself is permanently attached to the connecting device. The distal part of the connecting device can be angled in order to facilitate the desired direction of the implanted artificial artery.
