Abstract
An improved intra-aortic balloon catheter with a balloon membrane, a tip, and a co-lumen extruded tube having an outer lumen and an inner lumen between the inner and outer surfaces of the co-lumen extruded tube. The portion of the co-lumen extruded tube that defines the inner lumen and which is disposed within the balloon membrane is made from polyimide, a lubricous material, to facilitate guide wire tracking. The polyimide inner tube portion demonstrates good kink resistance and flexural stiffness. In a first alternative embodiment of the invention the co-lumen tube comprises an outer tube with an inner tube embedded in the wall of said outer tube. In a second alternative embodiment of the invention a longitudinal signal pathway is provided.
