Abstract

A vascular access device that prevents needle infiltration, provides a repeatable same-site access, and simplifies cannulation all while being minimally invasive and allows patients to self-cannulate.

First claim

What is claimed is:

1 . A vascular access device comprising: a center channel, a needle guide, and tissue anchors.

2 . The vascular access device of claim 1 wherein said tissue anchors are opposingly located side wings that extend perpendicularly away from said center channel.

3 . The vascular access device of claim 2 wherein said opposingly located side wings are adapted to prevent lateral movement and rolling.

4 . The vascular access device of claim 3 wherein said needle guide is funnel-shaped and includes an angled bore that runs through said funnel.

5 . The vascular access device of claim 4 further including a body defined by upper and lower sections that are releasably connectable.

6 . The vascular access device of claim 5 wherein said upper section defines one half of said channel and said lower section defines the other half of said channel and said channel is completely formed when said sections are connected.

7 . The vascular access device of claim 6 wherein said side wings are comprised of a first piece and second piece, said first piece connected to said upper section and said second piece connected to said lower section.

8 . The vascular access device of claim 7 wherein said first piece includes a boss having a fastener opening and said second piece includes internal threads that align with said fastener opening.

9 . The vascular access device of claim 8 wherein said boss of said first piece is rounded.
