Circulation support devices, systems, and methods

A method of using a vascular access device, the method comprising:

• advancing the vascular access device through a vessel in fluid communication with and proximal of an axillary artery, the vascular access device having an elongate tubular frame and a tubular extension extending radially outward from an outer surface of the elongate tubular frame;
• deploying the elongate tubular frame within the axillary artery with the tubular extension extending along the elongate tubular frame;
• creating an opening through skin and at a location proximate the tubular extension;
• and
• extending the tubular extension through the opening.

A stent assembly comprising:

• an elongate tubular frame having an inner surface and an outer surface, the elongate tubular frame defining a first opening at a first end of the elongate tubular frame, a second opening at a second end of the elongate tubular frame, and a third opening extending through the elongate tubular frame at a location between the first end and the second end;
• a coating extending along the inner surface of the elongate tubular frame and defining a first lumen extending through the elongate tubular frame;
• and
• a tubular extension defining a second lumen in fluid communication with the first lumen at the third opening.
