There are more than
one CARMAT heart connections! The patent, US8075617, concerns a Device for connection between a prosthesis
and the natural auricles, that is, a rigid prosthesis, implantable in
the pericardial cavity, with artificial left and right ventricles, once the natural ventricles have been removed. The device comes in two parts, one part
designed for connection to the patient’s left and right auricles, and the other
part comprising the artificial left and right
ventricles including openings with valves for communication with the artificial
left and right ventricles, and means for a rapid latching connection, to the
part already sutured to the patient’s left and right auricles. The whole device is also intended to avoid
torsion and compression of the connection to the patient’s auricles using a mobile and rotating suturing flange.
The abstract for US8075617 is included below with a patent image of the two parts of the prosthesis and an image of the actual manufactured device.
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.
