ABSTRACT:
An adapter having a first bore which facilitates the insertion and accurate positioning of an intra-aortic balloon, and is designed to fit within a synthetic graft which is sutured, for example, to the femoral artery. An annular groove is provided in the adapter, permitting the graft to be tightly tied thereto in the region of the groove. The silicone rubber blood-tight seal integrally formed with the adapter body, together with the adapter body, allow the catheter to slide freely therein, enabling positioning of the balloon in the aorta after the sutures are tied.
The adapter may further be provided with an additional bore for receiving an arterial pressure line. A separate silicone seal is provided to permit positioning of the pressure line while maintaining the integrity of the seal.
The adapter may be further employed with a Y-shaped cannula having a first arm for connecting blood from a by-pass pump into the aorta and having a second arm for insertion of an intra-aortic balloon assembly, the blood-tight seal being obtained through the use of the adapter.
