Abstract
A method of making hand-actuated retention catheter 5 is disclosed. The retention catheter includes a tube 12, an overcoat layer 14 encircling the tube 12 and a cavity 16 interposed between the tube 12 and the overcoat layer 14. The cavity 16 encircles the tube and includes a bulbous balloon portion 24 and an enlarged fluid reservoir portion 22 interconnected and separated by a catheter sleeve portion 26 which has a narrowed outside diameter. The expandable balloon portion 24 can be expanded by compressing the fluid reservoir portion 22. A variabale thickness coating of bond-preventing agent is formed on a polymeric structure prior to dipping in a polymeric material to form the overcoat layer.
