  • System and method for pressure filling of catheters
    Patent number: 5049130
    Abstract: A vascular catheter includes an elongate catheter tube having proximal and distal ends as well as a lumen extending between said ends. A catheter housing secured to the distal end of the catheter tube is covered by an elastic sheath. A vent path formed in the catheter tube housing is normally blocked by the sheath, but fluid being fed into the catheter lumen may be flushed through the housing by employing a sufficiently high pressure.
    Type: Grant

  • Self-venting balloon dilatation catheter and method
    Patent number: 4692200
    Abstract: Self-venting balloon dilatation catheter having a flexible tubular member with first and second lumens extending therethrough. An inflatable balloon is carried by the distal extremity of the tubular member in such a manner so that the first lumen extends through the balloon and is out of communication with the interior of the balloon and the second lumen is in communication with the interior of the balloon. A venting device is disposed between the balloon and the tubular member for venting air from the interior of the balloon but inhibiting the escape of liquid from the balloon.
