  • Interface needle and method for creating a blunt interface between delivered liquids
    Patent number: 6511472
    Abstract: An interface needle is used for connecting a syringe to a catheter to create a blunt interface between two or more liquids being delivered through the catheter. The interface needle is particularly useful for creating a blunt interface between a biocompatible solvent and a liquid embolic composition which is delivered to the body for treatment of various conditions including aneurysms. A system for liquid delivery with a blunt liquid interface includes a catheter or other cannula, an interface needle, and a syringe. The interface needle includes a tube extending from a distal end which delivers liquid to a lumen of the catheter bypassing a reservoir in the catheter hub to create the blunt liquid interface. One embodiment of the interface needle controls an injection pressure of high viscosity liquids.
