    摘要: An apparatus and method for the intravascular placement of a vena cava filter includes an outer sheath, an intravascular ultrasound catheter with an ultrasonic imaging element, a guide wire, and the vena cava filter that is to be deployed. The outer sheath, ultrasound catheter, and guide wire share a common central axis. The ultrasound catheter is enclosed by and is moveable relative to the outer sheath, and the guide wire is enclosed by and is moveable relative to the ultrasound catheter. In the stored position, the filter is secured between the outer sheath and the ultrasound catheter. When the apparatus is introduced into a vein, the ultrasound catheter provides real-time imaging of the vein for identifying the appropriate location for placement of the filter. Once such a location has been identified, the outer sheath is drawn back relative to the ultrasound catheter, exposing the legs of the filter, allowing the legs of the filter to spring free and attach themselves to the wall of the vein.

    摘要: An apparatus for the intravascular placement of a vena cava filter includes a flexible deployment sheath and an IVUC with an ultrasonic imaging element. These two components are joined together and oriented in a substantially parallel relationship with one another with the imaging components of the IVUC extending above or in front of the upper opening of the deployment sheath. Once the apparatus is appropriately positioned within the vena cava, as determined through ultrasonic imaging, a filter and its associated delivery system are inserted through the deployment sheath to the appropriate location for deployment.
