オフポンプ冠動脈バイパス術のための接触時に開くバルブをもつスタビライザの試作

抄録

In this paper, we show the two types stabilizer for off-pump coronary artery bypass grafting. One has no rubber flow channel, and the other has one. The both stabilizers have the valves that open when they contact with heart. The flow channel of former is stainless tube with suction hole. The structure of former is simple, but the thickness is thin because the stainless tube is under the valve element. On the other hand, the thickness of latter is thin, since the stainless tube is side of suction cups. However, the latter has the narrow flow channels which are difficult to form the rubber suction cups.
