Abstract
A valvuloplasty catheter comprising a catheter body having a through lumen, a tube extending through the lumen and having a distal end portion extending distally beyond the distal end of the catheter body and movable axially in the lumen relative to the catheter body. A radially expandable and axially contractable balloon is coupled, respectively, to the catheter body at the distal end portion of the tube. The balloon has a central region between the opposite end portions of the balloon which is of greater radial dimension in the relaxed condition than the opposite end portions and transition regions between the central region and the opposite end portions. The catheter body has a distal end portion which is less stiff than the region of the catheter body immediately proximal of the distal end portion of the catheter body.
