Abstract
A balloon for a dilatation catheter having a cylindrically shaped working section and tapered end sections which have essentially the same wall thicknesses. Upon deflation, the balloon collapses to a much smaller profile than conventional dilatation catheters. The balloon is preferably formed from a tubular parison which has a central thick walled portion. The balloon may be employed in dilatation catheters for angioplasty, prostatic urethra dilatations and other intraluminal dilatations.
