An assembly for reshaping a cardiac ventricle in a patient comprising an implantable device for reshaping a ventricle comprising a tether, a non-implantable tool which is detachably connectable to said implantable device and has a proximal portion and a distal portion opposite to said proximal portion; the implantable device further comprises an active anchor adapted to be detachably connected to the distal portion of the tool; the active anchor comprises an abutment portion adapted to abut against a structure of the ventricle; the active anchor of the implantable device comprises an adjustment device adapted to adjust the tensional state of the tether; the distal portion of the tool comprises an adjustment key adapted to cooperate with the adjustment device of the active anchor; the proximal portion of the tool comprises a maneuvering interface which is operatively connectable to said adjustment key for adjusting the tensional state of the tether by acting on the maneuvering interface of the proximal portion of the tool.

Device and assembly to repair a heart valve

A test bench assembly () for the simulation of cardiac surgery and/or interventional cardiology operations and/or procedures, comprising a passive heart (), wherein said passive heart () is an explanted or artificial or hybrid heart, said passive heart () having at least one pair of cardiac chambers () comprising an atrial chamber () and a ventricular chamber (); a reservoir (), adapted to house the working fluid; a pressure generator (), adapted to provide said passive heart () pumping said working fluid with the pumping function, said pressure generator () being fluidically connected both to said ventricular chamber () of said passive heart () and to said reservoir () by means of first fluid connection means; a pressure regulation device () which provides the working fluid in input to the atrial chamber () with the preload pressure, and the working fluid in output from the ventricular chamber () with the afterload pressure, said pressure regulation device () being fluidically connected both to said atrial chamber () of said passive heart () and to said ventricular chamber () of said passive heart () by means of second fluid connection means; wherein said pressure regulation device () comprises a single compliant element () for each pair of cardiac chambers () which provides the working fluid with both the preload and the afterload pressures.

Test bench assembly for the simulation of cardiac surgery and/or interventional cardiology operations and/or procedures

A test bench assembly for simulating cardiac surgery includes a passive heart having at least one pair of cardiac chambers with an atrial chamber and a ventricular chamber. A reservoir is adapted to house working fluid. A pressure generator fluidically connects both to the ventricular chamber of the passive heart and to the reservoir. A pressure regulation device provides working fluid in input to the atrial chamber with preload pressure, and working fluid in output from the ventricular chamber with afterload pressure. The pressure regulation device fluidically connects both to the atrial chamber of the passive heart and to the ventricular chamber of the passive heart. The pressure regulation device has a single compliant element for each pair of cardiac chambers, which provides working fluid with both preload, and afterload pressures.

A device for surgical training comprising: an external first layer () which simulates the subcutaneous fat; a second layer () internal to said first layer (), which simulates the muscle; a fourth layer (), internal to said second layer (), which simulates the perirenal fat; a kidney (), internal to said fourth layer (); said first, second and fourth layer having a sound propagation velocity between 1500 and 1550 m/s, an acoustic impedance between 1.5 and 1.7 10Kg/sm, an elastic modulus between 0.4 and 4.2 kPa, and being able to be perforated manually by surgical instruments.
