  • Publication number: 20090099517
    Abstract: An angioplasty balloon is disclosed and can include a body having a first end and a second end. An inflatable portion can be established between the first end and the second end. Moreover, a first reinforcing member can be wound around the body from the first end to the second end over the inflatable portion. Further, the first reinforcing member can be wound at a first winding angle with respect to a longitudinal axis. The first winding angle is in a range of fifteen degrees to forty-five degrees (15°-45°).

  • Patent number: 7331933
    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).

  • Patent number: 6511496
    Abstract: An intravascular filter device for capturing embolic particles entrained in blood flowing in an arterial vessel during an interventional procedure. The filter includes an expandable strut assembly and a filtering medium. Each strut is coated with an elastic polymer in order to minimize trauma to an arterial lumen upon deployment of the filter and to ensure secure adhesion of the filtering medium to the struts. Attached to the coating of the strut assembly is the filtering medium which is formed from a thin elastic polymer membrane containing a plurality of holes which allow blood to pass through filter while capturing embolic particles. The filtering medium is attached to the layer of polymeric material by laser welding, ultrasonic welding or adhesive bonding.
