摘要： The present invention is directed to a balloon catheter, such as a dilatation catheter and a stent delivery catheter with improved stiffness transition and specifically with no sudden changes in stiffness along the catheter length. The balloon catheters of the present invention may be used alone or be mounted with a stent in. The balloon catheters of the present invention may be used in peripheral, coronary, or neurovascular applications. The present catheter has more than one portion with different bending stiffness values, each portion comprising of components that gradually transition the bending stiffness of that portion to an adjacent portion, thus reducing the differential in bending stiffness in moving from one region to another, when the catheter is used alone or in combination with a stent in a stent delivery system.

摘要： 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).

摘要： The present invention is directed to a balloon for an intracorporeal catheter having at least a portion of its walls having radiopaque properties. The balloon is formed of a polymeric material, which has a single wall thickness of at about 0.001 inches to about 0.0125 inches while deflated. The radiopaque portion of the balloon has a thickness of about 0.00025 inches to about 0.012 inches, specifically about 0.002 inches to about 0.003 inches. The balloon is constructed of layers. The radiopaque material may be embedded within the film or deposited on the film to create radiopaque properties.
