  • Patent number: 8568435
    Abstract: A system for providing transvascular retrograde access in a central blood vessel of a patient. In some embodiments, the system has a handle; a catheter extending from the handle; and a tissue piercing element extending from the handle through the catheter, the tissue piercing element having a sharp distal tip adapted to extend from a distal portion of the catheter, the catheter and handle being adapted to be separated from the tissue piercing element, a distal portion of the tissue piercing element being adapted to serve as a guide for introduction of a device into the central blood vessel. The invention also includes a method of providing transvascular retrograde access to a central blood vessel of a patient.
