1. An obstructing device configured for deployment in an aortic valve, and for attachment to a leaflet of the aortic valve, comprising:
a hollow tubular member comprising:
a. a proximal opening at its proximal end, configured to be faced toward the aorta;
b. a substantially tubular surface extending distally from said proximal opening, configured to extend toward the left ventricle;
c. a distal end;
a grasping arm extending distally from said opening at the proximal end and configured for anchoring said obstructing device to an aortic valve leaflet;
wherein said hollow tubular member is tapered asymmetrically so that the obstructing device is configured to extends distally toward the left ventricle, and is configured to extend adjacent to and along the leaflet; wherein the distal end is either closed or comprises a small orifice; and
wherein said hollow tubular member is soft enough to radially collapse when blood flows outside and along said tubular surface from the distal end towards the proximal end and wherein said tubular member fills with blood and expands to reduces regurgitation through the aortic valve when the aortic valve closes on said hollow tubular member.
