  • Patent number: 7001358
    Abstract: The invention is a dilation catheter which comprises an elongated catheter shaft, a guide wire tube, and an angioplasty balloon. The distal end of the balloon is attached to the distal portion of the guide wire tube, and the proximal portion of the balloon is attached to the distal portion of the catheter shaft. A stiffening wire is attached to the inner wall of the catheter shaft at a plurality of points along its length. The distal extremity of the guide wire tube is decreased in size relative to the proximal portion of the guide wire tube. A fluid is contained within the guide wire lumen.
    Type: Grant
    Filed: March 19, 2003
    Date of Patent: February 21, 2006
    Assignee: Medtronic Vascular, Inc.

  • Patent number: 6368302
    Abstract: A Balloon dilation catheter comprising an elongated tubular shaft and an inner tube defining inflation and guide wire lumens. A dilation balloon is mounted on the distal end of the tubular shaft and communicates with the inflation lumen. The guide wire lumen extends through the balloon. A stiffening wire is positioned within the tubular shaft and has a proximal end secured in the proximal portion of the catheter. The distal end of the stiffening wire is anchored within the inner tube in an area adjacent the guide wire entrance port. The stiffening wire maximizes strength to the proximal portion of the catheter while maintaining flexibility in the distal end of the catheter as well as the balloon.
