Abstract

The present invention provides devices for beating heart surgery. The device separates the valve and the surrounding area from the rest of the vascular system so the operation procedure can be carried out while the heart is beating during the entire course of the procedure. This is made possible through a temporary valve (170) and two coronary artery conducts (130, 140) incorporated in the balloon-catheter system. The system provides better view and ease of operation and thus, reduces surgery related complication and pains.
