Hybrid-type stabilizer for off-pump direct coronary artery bypass grafting.

We have developed a mechanical stabilizer for use in off-pump direct coronary artery bypass grafting. We consider it an improvement on the sucker-type stabilizer, although it uses the mechanisms of the compressor-type. Our hybrid stabilizer effectively immobilizes the local heart surface with light compression and low evacuation. We believe that its use will eliminate the need for further immobilization and thus reduce cardiac invasiveness.
