Claim 1
Independent Claim
150 words
A method of securing a flexible annular balloon on a catheter shaft, comprising the steps of: forming a pair of spaced annular grooves in an outer surface of the shaft; positioning a first end portion of the balloon intermediate a first shrinkable annular sleeve and one of said grooves in a configuration with an end edge of the first end portion directed toward the other of said grooves; shrinking said first sleeve over said first end portion to secure said first end portion of the balloon in said one groove; positioning the remote end portion of the balloon intermediate a second shrinkable annular sleeve and the other of said grooves in a configuration with an end edge of the remote end portion directed toward said one groove; and shrinking said second sleeve over said remote end portion to secure said remote end portion of the balloon in said other groove.
