Abstract: According to various embodiments, a method and system to obtain access to a blood vessel underneath a skin layer that may preserve lifespan of the blood vessel and reduce executional skill variability may be provided. The method includes placing a guiding portion between the blood vessel and the skin layer; and configuring the guiding portion to receive and guide a needle to reach the same location of the blood vessel repeatedly and consistently; and forming a resultant scarred track between the blood vessel and the skin layer as the guiding portion is resorbed over time. The system includes a vascular access device configurable to first possess strength to penetrate through a tissue layer, subsequently possess flexibility to conform to the surrounding tissue beneath the tissue layer; and a guiding portion which may be resorbable, wherein the inlet includes a larger diameter compared to the outlet.
