As for this invention, outside it possesses the band which made the size which is accepted around the heart of the patient and is stratified in regard to the heart device, in addition as for that when filling up, in order to impress the pressure which is localized outside the heart, one which functioning is done filling up possible chamber is included at least between layer in the band. From, as for the filling up possible chamber, in order in the heart easing gear to apply radial power with inward, it is put in specification. In addition as for the area between the filling up possible chambers, completely with respect to blood vessel structure of the heart or, it is good being made the kind of size which forms the bridge which almost does not apply pressure.本発明は、患者の心臓の周りに受け入れられる大きさにされた層化されたバンドを有する外部心臓装置に関し、それはまた充填されたときに心臓の外側に局所化された圧力を印加するように機能する少なくとも一つの充填可能なチェンバーをバンド中の層間に含む。より特定には、充填可能なチェンバーは、心臓弁上に内向きで放射状の力をかけるように置かれている。充填可能なチェンバー間のエリアはまた、心臓の血管構造上に全くかまたは殆ど圧力をかけない橋を形成するような大きさにされて置かれていても良い。
