摘要：
The present direct cardiac compression (DCC) design, termed Cardiac Resynchronization Compression Sac System (CRCSS), combines the mechanical and electrical characteristics associated with DCC and cardiac resynchronization therapy (CRT), respectively. The CRCSS comprises a shell, at least one opening on the shell, at least one inflatable balloon, and a pumping system. The shell is custom manufactured to substantially conform to the contour of a portion of a heart, the contour being obtained by an imaging system. The opening on the shell is designed for passing pericardial fluid so as not to impede the myocardial contraction. The inflatable balloon attaches to at least one predetermined location of the inner surface of the shell. Furthermore, the shell naturally positions in the pericardium space without resorting to any artificial force to prevent it from dislodging from the heart. When the inflatable balloon inflates at least one ventricular free wall of the heart is compressed.
