  • Apparatus and method for extrusion of thin-walled tubes
    Patent number: 7425291
    Abstract: The present invention provides an apparatus and method for manufacturing polymeric thin-walled tubular members, which are well-suited for use as vascular grafts. The apparatus of the present invention enables extrusion of a tubular member having an extremely thin wall thickness so as to facilitate passage through tortuous vascular passageways. The apparatus achieves uniform wall thickness in a tubular member by establishing and maintaining axial alignment of a ram having a concentrically disposed guide rod therein with a die supported in concentric relation to the guide rod.
    Type: Grant
    Filed: September 22, 2004
    Date of Patent: September 16, 2008
    Assignee: Scimed Life Systems, Inc.
    Inventors: James Venditti, Howard Wolek, Alice Wong, David J. Sogard, Jason P. Hill, Timothy S. Girton, Christopher B. Brodeur
