Catheter having a coextruded fluoropolymer layer |
摘要 |
A catheter shaft including an elongate tubular member including a first polymeric layer and a second polymeric layer bonded to the first polymeric layer. The first polymeric layer is formed of a polymer generally not bondable to fluoropolymers, and the second polymeric layer is formed of a fluoropolymer bonded to the polymer of the first polymeric layer. The fluoropolymer of the second polymeric layer is a functionalized polyvinylidene fluoride which has a bonding affinity to the polymer of the first polymeric layer. The functionalized polyvinylidene fluoride includes reactive functional groups chemically bonded to a polymer chain of a polyvinylidene fluoride which readily bond to the polymer chain of the polymer of the first polymeric layer. |
