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.
Claims9
An article comprising a multi-layer polymeric material film comprising at least first and second layers, each layer having an inner and an outer surface, said first and second layers being directly bonded to each other over a coextensive area along respective outer and inner surfaces, each of said first and second layers having an at-rest configuration defining an at-rest area on said respective outer and inner surfaces corresponding to said coextensive area, the at-rest area of said first layer outer surface being smaller than the at-rest area of said second layer inner surface, the at-rest configuration being when said respective outer and inner surfaces are unstressed.
