摘要：
A guide catheter can align itself with a blood flow stream to thereby help direct a guidewire or other elongate device transmitted from the guide catheter through an orifice of a heart valve, for treatment of heart conditions such as valvular stenosis. For example, a guide catheter can align itself with a blood flow stream to thereby help direct a guidewire or other elongate device transmitted from the guide catheter through an orifice of a heart valve, or any other normal or abnormal passage in the body against the direction flow. This device can also be used to localize and repair leaks where a fluid flow jet is present in submerged or fluid-filled chambers. A device for centering a medical instrument in a body conduit includes a framework of frame members, defining a lumen with open ends； and a covering.
