  • Protective sheath for catheters
    Patent number: 6592569
    Abstract: A sheath is provided for covering a device on the distal end of a catheter system during the delivery of the device to an intravascular site within a patient. The sheath can be added to any delivery system prior to use and is intended to protect a deliverable device, such as an intravascular stent, from being dislodged prematurely from the catheter system or moved with respect thereto.
    Type: Grant

  • Catheter for placement of therapeutic devices at the ostium of a bifurcation of a body lumen
    Patent number: 6544219
    Abstract: The catheter assembly includes an expandable member mounted to the distal end of a placement catheter, for delivery of a therapeutic device in one of the branch vessels of a bifurcated vessel. The catheter assembly includes lumens for a tracking guide wire and a positioning guide member for placement of the therapeutic device. The therapeutic device is mounted on the expandable member, the tracking guide wire is placed into the target branch vessel, and the placement catheter is then introduced over the tracking guide wire. A positioning guide member is introduced through the catheter, extended through an exit port in the catheter proximal to the expandable member, and then placed in another branch vessel of the bifurcation. The placement catheter then is advanced until the positioning guide member engages the vessel carina between the branch vessels, and the therapeutic device then may be placed accurately in the target branch vessel.
