Method for making medical balloon catheter

摘要

A method for making a medical balloon catheter in a single molding operation employs a parison which is molded and biaxially oriented by the use of first and second pressurization stages. The starting material is in the form of a tubular parison with a reduced diameter portion which is made of a biaxial orientable polyamide or polyetheramide material. The resulting balloon can be attached to a catheter that includes a tapered or stepped distal end without further shaping or modification of the balloon ends.
