摘要:
The present invention relates to methods of transvascular retrograde access placement and to devices that facilitate these methods. For purposes of the present invention, transvascular retrograde access placement generally comprises the insertion of a vascular catheter into a central blood vessel through the puncturing of the central blood vessel from the inside of the central blood vessel with a needle or other similarly configured device, or a needle-tipped guidewire of the present invention, and exiting that needle from the patient through the skin rather than the traditional approach of inserting a needle from the outside of the skin surface to the inside of a blood vessel.
