摘要
Disclosed is a system for vascular access, where the system allows for transitions between retrograde and antegrade access without generation of multiple access sites and without inducing extensive vascular damage. In embodiments, the system can include a vascular access portion including a body with a first lumen for preferentially providing access in a retrograde direction into a vessel, and a second lumen for preferentially providing access in an antegrade direction into the vessel. The body can be transitioned (e.g., by way of expansion, contraction, or other deformation mode) between a retrograde delivery mode and an antegrade delivery mode.
