Abstract:
A dilatation balloon, comprising:a length of tubing of polymeric material comprising Nylon 12, which tubing had been radially expanded to a predetermined balloon diameter;said dilatation balloon has a collapsed profile which has a diameter less than said predetermined balloon diameter, said dilatation balloon further having a non-distended, inflated working diameter at which the dilatation balloon is inflated to its said predetermined balloon diameter, and said dilatation balloon also exhibits a maximum stretched inflation diameter to which the dilatation balloon is expandable without bursting under needed dilatation conditions, said maximum stretched inflation diameter exceeds said predetermined balloon diameter by between above 5 percent and about 30 percent; andsaid dilatation balloon has a calculated tensile strength of between 15,000 psi and 30,000 psi.
