Abstract
The present invention is directed to balloon catheter having a compression member securing one or more balloon skirts to the catheter shaft. The compression member may be a band or coil that sealing secures the balloon skirt to a catheter shaft. Metallic compression members may be swaged to compress the skirt against the shaft, and thus provide a uniform seal between the balloon skirt and the catheter shaft. The compression members are especially useful when the balloon is formed of a fluoropolymer, such as expanded polytetrafluoroethylene (ePTFE) or polyterafluoroethylene (PTFE).
