Abstract
A medical device such as a catheter, stent or balloon, is formed by depositing a radiation curable composition on a form made of ice or wax. The deposited composition may be cured by irradiation, suitably with UV light. Complex structures can be built up if the deposition or curing is achieved imagewise. Compositions which photocure to polyester, polyamide or polyimide may be employed. A particular structure is a balloon for a rapid exchange catheter which has a guide wire lumen passing through the balloon cone walls.
