Embodiment Construction

[0030] exist figure 1 The cardiac prosthesis of the present invention, shown in exploded view in FIG. It consists of a rigid body 1, artificial left and right ventricles ( figure 1 (not visible in ) is arranged in this rigid body 1, the ventricle is provided with means 2, 3 for connection to the patient's natural right and left atrial appendages (not shown) and for connection to the aorta and pulmonary artery respectively Apparatus 4,5.

[0031] Means for connecting the natural left and right atrial appendages include:

[0032] Frame plate 2, which forms an integral part of the rigid body 1, and includes a hole 6 communicating with the artificial right ventricle and a hole 7 communicating with the artificial left ventricle, a valve ( figure 1 not shown in) arranged in said holes 6, 7; and

[0033] Frame plate 3, which can be detachably connected to frame plate 2 and comprises holes 8, 9 which can be arranged so that when said frame plates 2 and 3 are in a precise position ...

Abstract

Device for rapid connection between a totally implantable heart prosthesis and natural auricles. According to the invention, said prosthesis comprises: fastening means (16, 25) for fastening an end of one of the lunettes (2, 3) to the other lunette (3, 2), said fastening means being able to permit folding of said lunettes relative to each other; guide means (10, 11, 20, 21) for guiding said lunettes relative to each other before and during fastening and also during folding; and snap-fit means (19, 26) for engaging said lunettes on each other in the operating position corresponding to the end of said folding.

Description

technical field [0001] The present invention relates to a device for quick connection between a fully implanted cardiac prosthesis and a natural atrial appendage. Background technique [0002] Document US-5135539 already discloses such a cardiac prosthesis implantable in the pericardial cavity of a patient, capable of replacing the patient's natural left and right ventricles after their removal. The cardiac prosthesis comprises a rigid body in which artificial left and right ventricles are arranged, said artificial ventricles being provided with means for quick connection with said patient's natural right and left atrial appendages, comprising: [0003] a first bezel forming part of said rigid body and comprising first and second holes respectively connected to the artificial left ventricle and the artificial right ventricle via valves connectivity; and [0004] The second frame plate, the second frame plate includes third and fourth holes, the third and fourth holes are r...
