Claim Text:
1. A balloon valvuloplasty catheter comprising: a balloon disposed at a distal end of an elongated shaft; a non-compliant distal bulb of said balloon having a fully inflated distal bulb diameter at a fully inflated distal bulb pressure of zero to 0.5 atm; said non-compliant distal bulb consisting solely of non-compliant material; a semi-compliant proximal bulb having a smaller diameter than said distal bulb diameter at said fully inflated distal bulb pressure; a waist portion of said balloon positioned between said distal bulb and said proximal bulb; said waist portion having a fully inflated waist diameter that is smaller than said fully inflated distal bulb diameter at said fully inflated distal bulb pressure; said proximal bulb having a fully inflated proximal bulb diameter at a pressure higher than said fully inflated distal bulb pressure; said fully inflated waist diameter is smaller than said fully inflated proximal bulb diameter at a pressure higher than said fully inflated distal bulb pressure.
