ABSTRACT:
A guidewire assembly particularly suitable for valvuloplasty procedures have an outer tubular member a first shapable core member fixed within the outer member and a second stiffer core member which is axially movable within the out tubular member. The first core member preferably has a double curvature shape with the most distal curvature having a much smaller radius or curvature than the second curvature. When the movable core member is moved proximally, the fixed core member assumes its shaped form and thereby changes the shape of the guidewire. The double curvature shape prevents the traumatic engagement of the distal tip of the guidewire with the lining in the heart chamber and also provides supports to the guidewire when disposed through the heart valve.
