Abstract: A device for connection between a heart prosthesis and a person's natural auricles includes a structure for joining to the natural auricles with individual suture attachments mounted so as to be free in rotation and movable.

Abstract: Device for rapid connection between a totally implantable heart prosthesis and natural articles. 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.

Abstract: One-piece heart prosthesis implantable in an anatomical position. According to the invention, the artificial left and right ventricles (2, 8) have general directions (14, 15) arranged in an asymmetrical V shape, such that said ventricles approach each other as they move away from the means (6, 12) of connection to the natural left and right auricles, and the individual hydraulic actuators (7, 13), associated respectively with said artificial left and light ventricles (2, 8), are arranged near each other, in proximity to said artificial left ventricle (2).

Abstract: According to the invention the rotary pump consists of an external gear (13) with internal teeth (16) in the form of a squirrel cage, and an internal gear (9), housed in an off-centre manner in the interior of said external gear (13) and fitted with external teeth (9D) intermeshing with said internal teeth (16) and consisting of a number of inferior teeth of a unit with the number of teeth of the later. The rotation means of said external teeth (13) comprise at least a bearing (11, 12) centrally laid out in a flange end (14,15) of said aforementioned external gear (13) and the aforementioned external gear (13) is at least partly dismantled in order to introduce said internal gear (9).
