Auxiliary artificial heart of an embedded type

An artificial heart inserted in a ventricle of a human heart having an aorta valve, including:

• (1) a cylindrical cardiac apex ring fixedly embedded in a cardiac apex of said human heart after said cardiac apex has been cut;
• and
• (2) a main body of said auxiliary artificial heart comprising:
• (a) an axial flow type cylindrical pump section having a proximal end and a distal end and inserted in said ventricle of said human heart through said cardiac apex ring;
• (b) a nozzle section extending outward from said distal end of said pump section and inserted in an aorta of a human body through said aorta valve in said human heart;
• (c) a driving section having a driving shaft provided on said proximal end of said pump section and externally of said human heart, for driving said pump via said driving shaft, said driving shaft having an outer peripheral surface;
• (d) a sealing mechanism provided between said driving section and said pump section, for maintaining said driving shaft in a liquid tight state and preventing blood from entering said driving section from said pump section;
• and
• (e) a sealing liquid chamber surrounding said driving shaft between said sealing mechanism and said driving section, said sealing liquid chamber being filled with a sealing liquid.
