Method for bonding polyurethane balloons to multilumen catheters |
摘要 |
A process for making a balloon for use on a multilumen catheter using as a form for the balloon a mandrel having at least one groove and at least one score line. The mandrel is rotated while metering into the groove a thermoplastic adhesive. The balloon stock is formed by coating the mandrel with a solid thermosetting polyurethane prepolymer. After cooling of the mandrel a film of thermoplastic adhesive is wrapped over the balloon at about the score line. Once the assembly is cured the balloon stock is removed to result in a balloon having an adhesive film on the internal wall at one end and an adhesive film on the external wall at the other end.
