Abstract
The present invention sets forth a balloon catheter device adapted for use with catheters in angioplasty and/or valvuloplasty procedures which is expandable under fluid pressure and incorporates a plurality of stiffening means to resist deformation of isolated portions of the balloon when the balloon is expanded during the treatment procedure. Reinforcing means may also be provided to coact with the stiffening means to strengthen the balloon and/or to assist in the fixing of the location of the stiffening means.
