Methods of transvascular retrograde access placement and devices for facilitating therein
First Claim
1. A method of performing transvascular retrograde access placement in a central blood vessel of a patient, the central blood vessel selected from a group consisting of a jugular vein or a subclavian vein, said method comprising:
- inserting a vascular catheter into a femoral vein or an antecubital vein and positioning said vascular catheter within said central blood vessel such that a portion of said vascular catheter faces a desired exit site on a wall of said central blood vessel, the vascular catheter comprising an angled-tip;
passing a needle from said vascular catheter through said desired exit site on said wall of said central blood vessel and skin of said patient; and
passing an end of a secondary vascular catheter through said exit site and into said central blood vessel.

Abstract
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.
