Apparatus connects a pump to a chamber of a heart. A cuff attaches to the heart, the cuff having a flange portion for attaching to a surface of the heart and a sleeve portion extending from the flange portion. An inflow conduit has a first end for inserting into the heart, an intermediate portion for attaching to the sleeve portion of the cuff, and a second end for conveying blood from the heart to the pump. An expansion tool is releasably mounted with the inflow conduit to slide longitudinally within the inflow conduit. The expansion tool has a blunt tip for punching through the heart into the chamber at a distal end and a manual grip at a proximal end for pulling the expansion tool out from the inflow conduit. The expansion tool has a sliding seal substantially adjacent the blunt tip so that after punching into the heart and joining the inflow conduit to the sleeve portion of the cuff, the expansion tool can be withdrawn from the inflow conduit resulting in gradual entry of blood into the first end and withdrawal of air from the second end.拡張ツールが、ポンプの流入導管を心臓に接続する助けとなる。拡張ツールは、流入導管の内部を長手方向に摺動するように流入導管に解放可能に取り付けられる。拡張ツールは、遠位端には、心臓を通して腔内へ孔を開けるための丸まった先端を有し、近位端には、流入導管から拡張ツールを引き出すための把持部を有する。拡張ツールは、丸まった先端に実質的に隣接する摺動シールを有し、したがって、心臓に孔を開け、カフを介してスリーブ部分を心臓に接合した後に、拡張ツールを流入導管から引き抜くことができ、それにより、第１の端部に血液を徐々に進入させ、第２の端部から空気を抜き出す。【選択図】図６
