Abstract
A method of constructing a miniature balloon (96) for use as a catheter in blood vessels (10) involves spraying aerosolized particles to form successive coats of a highly diluted silicone-rubber solution (42) onto a Teflon coated mandril (48,50) having a roughened surface. Each coat is allowed to cure somewhat prior to applying a further coat. The silicone-rubber solution comprises 5% silicone and 95% solvent. The balloon products of this process have thinner, more delicate thickness-controlled walls than balloons made by the prior-art process of dipping.
