IN 1966, the implantation of a mechanical auxiliary ventricle in two patients gave evidence that the prosthesis may be feasible as a permanent circulatory-assist device in patients with intractable left ventricular failure.1,2 In this paper modifications of the U-shaped ventricle and results of animal experiments are described.

Materials and Methods  The implantable components of the mechanical ventricle consist of a flexible Dacron-reinforced silicone rubber pumping chamber, an outer casing with an air tube, and myocardial electrodes; the external components include a supply of compressed air, a solenoid valve, and an electronic synchronizing device.3 In the experiments reported here, the following modifications of this system were employed:1. A one-piece housing of resin-coated fiber glass covered with silicone rubber (Fig 1).2. An improved implantation technique in dogs that facilitates transection of the aortic arch between the two anastomoses.3. An applanation pressure transducer which can be fitted over
