Zusammenfassung:A method to laminate ePTFE to Nitinol structures, such as an expandable sheath. Initially, the nitinol braid is slid into an outer ePTFE liner. An inner ePTFE liner is slid into the nitinol braid. The assembly of nitinol braid and inner and outer ePTFE liners is slid onto an inflatable silicone tube. The assembly inserted onto the silicone tube is placed in a heated die. The silicone tube is pressurized, causing it to inflate, forcing the inner ePTFE liner into contact with an inner surface of the nitinol structure. The die is cooled. The silicone tube is depressurized. The laminated structure is then removed from the die and the inflatable silicone tube.
