Problems solved by technology

However, the appendages are known to comprise flexible and easily deformable tissue, and since they are not completely independent (as they are connected by the interatrial septum), the appendages may not be in avoidable torsion and compression relative to the second frame plate best orientation
In this case, this orientation defect can only be corrected by performing a new suture after separating the auricle from said sewing ring

Abstract

Device for connection between a heart prosthesis and the natural auricles. According to the invention, the means of joining to the natural auricles are formed by individual suture attachments (11) mounted in such a way as to be free in rotation and to be movable.

Description

technical field [0001] The invention relates to a device for connection between a cardiac prosthesis and a natural atrial appendage. Background technique [0002] Document US-5135539 already discloses a cardiac prosthesis implantable in the pericardial cavity of a patient, which enables the removal of the patient's natural left and right ventricles. 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 respectively connected with the natural left atr...
