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 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： An intravascular catheter of the invention has an improved distal tip with an expanded portion which has exterior transverse dimensions greater than an unexpanded portion proximally adjacent to the expanded portion. In one presently preferred embodiment the catheter has an inflatable balloon with a distal skirt which is secured to the unexpanded portion of the distal tip so as to provide an even exterior surface thereto.

摘要： A self-expanding filtration element is fitted to the distal end of a catheter while a sheath for constraining such element to a reduced diameter is mechanically manipulatable from the proximal end of the device. The entire device is maneuvered into position over a guide wire and deployed prior to treatment of the body lumen at an upstream location. After completion of the treatment procedure, the filtration element is collapsed and constrained within the sheath to retain any embolic material that has been captured and allow it to be safely removed from the vasculature. The device may be combined with a primary treatment modality and its low profile allows the constrained filtration element to be removed through a deployed stent.

摘要： An assembly for delivering a self-expanding stent to an intraluminal location comprising a guide wire, a retainer to secure the stent to the guide wire in a compressed configuration, and a release member to release the stent from the retainer and allow the stent to assume an expanded configuration. The stent may be compressed by axial elongation, radial compression, or linear elongation into a generally tube-like configuration. The release member may operate the retainer to release the stent or urge the stent away from contact with the retainer.

摘要： A system used in a blood vessel when an interventional procedure is being performed in a stenosed or occluded region, which is capable of accurately treating an affected area in a blood vessel while preventing adverse effects for healthy tissue. The system includes a catheter which is positionable in a blood vessel at the interventional procedure site. The system further includes an interventional instrument such as a self-expandable stent which may be deployed in the blood vessel at the interventional procedure site. The system also includes an extendable member, adapted to be about the interventional instrument for delivery of the interventional instrument to the interventional procedure site, and to be retractable from extending about the interventional instrument for enabling the interventional instrument to expand at the interventional procedure site. The system further includes movement preventing elements, for preventing axial movement of the interventional instrument in a support region of a catheter elongated shaft, during retraction of the extendable member from extending about the interventional instrument, for enabling accurate deployment of the interventional instrument.
